Difference Between C, C++ and Java (Complete Comparison)

Difference Between C, C++ and Java (Complete Comparison)

Today, we will talk what is difference between difference between C C plus plus and java with step by step comparison.

When we talk about software development there are many transitions and updates happening now and then which always results in evolving of many programming languages.

C, C ++ and java are one example of such evolution which made a great impact in the software industry and considered as the backbone of all programming languages.

Layman terms Concepts

Starting with the conceptual differences between these three let’s understand it first in layman terms.

C, C++ and java are having the same differences as it is between you your father and your grandfather.

  • Let’s compare grandfather with c
  • Father with C++
  • Java being you

Let’s Compare these three languages with this example.

C Programming Language

C Programming Language
C Programming Language

As the oldest one is your grandfather who is still alive and trying to shape himself according to the present world but still the most valuable with knowledge and experience of three generations.

He is the most respected one and known as the head of the family.

The same goes with c.

C is the oldest one but still alive.

Many developers are still using C programming language to develop some applications.

C prompting language is shaping itself according to the present world and still in 2021 it is the most valuable.

It is having experience of three generations which is:

  • Low level
  • Assembly
  • High level language

C programming language is the most trusted one and it is also called as the mother of all languages.

C++ Programming Language

C++ Programming Language
C++ Programming Language

Your father being younger than your grandfather but still son of your grandfather.

So, must have inherited many qualities from him and also must be having his own new updated features.

He must be having a well-defined small friend circle and anybody in the family thinks twice before talking to him.

Likewise C++ is also younger than c and c++ is developed nothing but by a c language.

So, it is the son of the C programming language that means it must have inherited many qualities from C language but it is having its own new updated feature also which is OOPs concepts.

C++ is having object oriented prompting concept which is his new feature.

C++ is having its well-defined small friend circle that means it works with all different kinds of languages too such as database languages and front-end languages.

Others in the family of programming languages are afraid of c plus programming language because C++ programming language is better than the other programming languages.

Java Programming Language

Java Programming Language
Java Programming Language

The most youngest in the family facing a lot of challenges in life be it in school college or company but somehow you’re breaking boundaries to be always in top.

You are updating yourself rapidly to face all the difficulties and you talk to everybody around.

Many of your friends are learning from you to become like you and some other students who are jealous of you are using your ideas to achieve success which is in a way making you famous.

So, talking about java java is the most youngest one in comparison to c and C++ and yes java has faced a lot of difficulties and challenges in life but somehow java has break all its boundaries and have come up at the top.

Java is updating itself rapidly to face all the difficulties whatever it is facing and the other programming languages are learning from java and trying to become like java programming language.

Now there are some jealous languages which is nothing but spring which is using the ideas of java that means it is using the features, concepts and libraries of java to achieve success.

But in turn in a way it is actually benefiting java programming language itself.

So, that was the difference between c c plus Plus and java in layman terms.

In spite of all these qualities of java always remember that your father and grandfather are genius and have more knowledge than you.

That means if you are java then your father and grandfather that means c and C++ are genius and is having more knowledge than java programming language that’s why in current era in the year 2021 also people and developers are still using c and c++ programming language to develop some of the applications.

Conceptual difference between C, C++ and Java

Conceptual difference
Conceptual difference

Now let’s move ahead with the conceptual differences and let’s see what is the conceptual differences between C, C++ and java programming language.

Going ahead let’s see the first conceptual difference between these three languages which is nothing but the programming paradigm so which programming paradigm is used in these three languages let’s look upon that.

Programming Paradigm

Programming Paradigm
Programming Paradigm

For C Programming language we use the procedural programming language concept.
In C++ it is an object oriented programming language.
When it comes to java, java is a cross-platform pure object-oriented programming language.

Now what is the meaning of all these three things?

C is a procedural programming language that means it follows step step-by-step procedure execution.

When it comes to c++ it follows OOPs concept which nothing but follows five major concepts of oops.

When it comes to java, java also follows OOPs concepts and plus it also follows multi-threading concept with a cross-platform technique.

That means we can use java and write and run java code anywhere in any platform.

Developer Difference

Developer Difference
Developer Difference

Now who is the developer for c language C++ and java.

Let’s look at that.

C programming language is developed by a Dennis Ritchie in 1972
Similarly C++ language is developed by Janus straw stop in 1979.
And java is developed by James gosling in 1991.

These are the names of the developers who have developed these Programming languages.

Origin Difference

Origin Difference
Origin Difference

C programming language is based on assembly language.
Whereas C++ programming language is based on c language.
And java programming language is based on c and C++.

This is the same difference which we have seen in the layman terms difference where we said that c Programming language is nothing but your grandfather.

C++ if your father and java is nothing but you and that’s the same difference which is written here.

Platform Dependency Difference

Platform Dependency Difference
Platform Dependency Difference

Platform dependency means which language is dependent on specific platforms.

So, if we talk about c language, c language is a platform dependent programming language that means it totally depends on which platform or which operating system are you using while working with c programming language.

While coming to c plus C++ is also platform dependent programming language.

But when it comes to java, java is a platform independent programming language that means you can write the java program anywhere and you can run it also anywhere.

Approach Difference

Approach Difference
Approach Difference

Now which programming language follows what kind of approach that’s what we are going to talk about in this particular topic.

So, C follows top down approach that means we write the main method first and then we write the rest of the program.

So, the step-by-step execution happens from line by line from starting to end.

When it comes to c plus it follows bottom up approach that means main method can be written anywhere wherever you want.

The same happens to java, java also follows bottom up approach.

Compiler Difference

Compiler Difference
Compiler Difference

C has only one compiler that means compiler actually converts your code into machine language that means a byte code.

So, all your codes whatever you have written is getting converted into machine specific language so that the machine can understand your code and can process it.

For that c programming language is having only one compiler.

C++ is also having only one compiler.

Whereas java has the combination of both a compiler and an interpreter.

This is one of the advantage of java programming language.

File Extensions Difference

File Extensions Difference
File Extensions Difference

If you’re writing a programming file for c or C++ or java now how do you have to save it with what file extension?

For C it follows .c file extensions and the c plus follows .cpp file extensions.

Similarly java follows .java file extension.

This is very important to remember for all the freshers and beginners because you will be trying to write a code in this specific language and you must have to save the file.

So, you should know that what is the correct file extensions for these particular languages.

Keywords Difference

Keywords Difference
Keywords Difference

How many keywords are used in all these programming languages?

Let’s show you the count of it.

  • C supports 32 keywords
  • C++ supports 63 keywords
  • Java supports 50 keywords

Keywords are nothing but the predefined terms which we use in our programming language to make it more easy and simplify it.

So, c programming language is having 32 keywords that means we can use these keywords to write a program very easily.

Same goes to C++ and java.

Data types Difference

Data types Difference
Data types Difference

So which language is using structure and union as the data type and which language is not?

  • C supports structures and unions.
  • C++ also supports structures and unions.
  • But if you go ahead with java, java does not support structures and unions.

Why?

Because James Gosling wanted to make java very simple and easy.

So, there are 8 data types which is there in java namely:

  • int
  • care
  • string
  • float
  • long
  • double
  • boolean

Inheritance Difference

Inheritance Difference
Inheritance Difference

Let’s go ahead and see which language follows inheritance and which language doesn’t follow inheritance.

In these three programming languages:

  • C does not support inheritance.
  • C++ does support
  • Java does subordinates accept multiple inheritance.

Now that doesn’t mean that java does not support multiple entries.

It’s a fact that you can use interface to work with multiple inheritance in java which is resulting in java supports inheritance.

Pointers Difference

Pointers Difference
Pointers Difference

Pointers are nothing but which saves the value within help of address of that particular memory so we play with the value and we play with the address of that particular memory.

  • C language supports pointers.
  • C++ language also supports pointers
  • Java removed the concept of pointers from itself.

Overloading Concept

Overloading Concept
Overloading Concept

When you talk about the overloading only one oops concept comes into our mind which is the polymorphism.

Now because c does not follow oops concept so c language does not support overloading.

But when it comes to C++ it does support function overloading and polymorphism because C++ is having oops concept.

Java does support overloading but it does not accept operator overloading.

Exception Handling Difference

Exception Handling Difference
Exception Handling Difference

Exception handling is one of the concept which is nothing but the unwanted risk or unwanted situation which happens how you can handle that in these programming languages.

C does not support exception handling and that is one of the drawback of c language.

C++ does support exception handling and mostly exception handling is used in java concept.

So, java also does support exception handling.

Memory Allocation Difference

Memory Allocation Difference
Memory Allocation Difference

Now which method or which function do we use to allocate the memory in these programming languages?

C language uses “Malloc” and “Kellogg” which is nothing but a predefined method to allocate the memory in c language.

C++ uses the “New” keyword and the “delete” keyword to save the memory in the c++ programming language.

Java uses garbage collector to do the same.

Constructors & Destructors Difference

Now if you don’t know what is constructed it’s nothing but giving you an initial value for all your variables is nothing but an ignition.

Destructors are nothing but the opposite of constructors

C does not have either constructor or destructor because this concept was not even created or initiated while they were working with C programming language.

C++ has both constructor and destructors.

Java has constructors but there is no need of destructors in java.

Connectivity Difference

Connectivity Difference
Connectivity Difference
  • C does not support database connectivity.
  • C ++ also does not support database connectivity.
  • Java does support connectivity by the help of JDBC which is java database connectivity.

So, using JDBC or ODBC drivers you can actually connect java with the database.

Data Security Difference

Data Security Difference
Data Security Difference

C does not support encapsulation so there is low data security.

Encapsulation is one of the oops concept which is nothing but helps in data security.

When it comes to C++ it does support encapsulation and that is why it is having a high data security.

Same goes to java as well.

Java does support encapsulation thus high data security.

Multi-Threading Concept Difference

Multi-Threading Concept Difference
Multi-Threading Concept Difference

If you have given a process in a programming language then that process will be divided into several threads and that is what is called as multi threading or multitasking.

  • C does not support this.
  • C++ does not support multi threading
  • Java does support multi-threading techniques.

This is also one of the pure advantage of java programming language.

Preprocessor Directives Difference

When it comes to preprocessor directives c supports header files which is #include, #defined etc.

Same goes for c++.
C++ also supports preprocessor directives like #include.

When it comes to java, java actually does not support pre-processor directive but it supports something like that which is also called as packages or import commands to access all their libraries and packages.

Why do we use C, C++ and java programming language?

Why do we use C, C++ and java programming language?
Why do we use C, C++ and java programming language?

This particular question tells about the primary features of all these programming languages.

Let’s answer why?

Why Do We Use C Programming Language?

Why Do We Use C Programming Language?
Why Do We Use C Programming Language?

When we talk about C programming language, it is the most structured language out of all the programming languages being in the market.

It is having the future of portability and it is also having a rich library that means a large amount of libraries are provided by a C which we can use to write a program.

And also it follows a dynamic memory allocation which is nothing but the Malloc and Kellock method which we have already discussed in the previous conceptual differences of memory allocation.

These are some of the features which makes people use C Programming language.

Why Do We Use C++ Programming Language?

Why Do We Use C++ Programming Language?
Why Do We Use C++ Programming Language?
  • C++ is powerful and fast.
  • It is flexible.
  • The speed is really very good in C++ Programming language.
  • It helps in compilation.

These are some of the features of C++ programming language because of which developers love to use c ++ programming language.

Why Do We Use Java Programming Language?

Why Do We Use Java Programming Language?
Why Do We Use Java Programming Language?

As you have already seen in the conceptual difference of data security, It is having an encapsulation concept which means shortage of security risks are there that means the data of yours is secure when you are using java programming language.

Java programming language is platform dependence that means it doesn’t matter in which platform or in which operating system are you writing the program of java.

It will work in Linux also, windows also and any other operating system.

It follows the concept of multi-threading which is one of the greatest advantage of java programming language and java programming language is having the feature of stability.

Where do we use C Programming Language?

We use c priming language in making database softwares like My SQL.

My SQL is properly developed by C programming language.

C programming language is also used to develop gaming and animation applications.

For example Adobe.

It is used to create the compilers.

Most of the compilers which is used in many programming languages are designed using c programming language

And last but not the least it is also used to create graphical user interface based applications.

Where Do We Use C++ Programming Language?

C++ is also used in creating compilers and animation softwares.

One best thing about C++ is that it is used to create operating systems that means you can use C++ programming language to build and develop operating systems like windows, Linux or Unix.

One very cool feature about C++ is that you can create web browsers like Chrome,Mozilla, Firefox Opera Mini and Safari using c++ programming language.

Where Do We Use Java Programming Language?

Java programming language is mostly used in mobile applications, desktop applications, enterprise applications and gaming applications.

So, mainly java programming language is used to create and develop some kind of applications which will work in mobile and which will work in desktop.

Enterprise means all the banking applications and the gaming applications.

Final Words

So that was all about the differences between C C++ and java programming languages we have seen the differences in layman terms and also we have seen the conceptual differences and then we discussed about why do we need to use these programming languages and where can we use these programming languages to develop what kind of applications. I hope our content will be Helpful for you go ahead and start learning language which you like the most.
