You must be unaware of the Difference Between C And C++ if you are new to the programming languages. Both c and c++ programming languages are generally used for application development. If you wish to learn this programming language then you have arrived at the right place! In today’s article, we will study the difference between c and c++ operators in detail. Here, I have also compared these terms with python and java. Make sure you do not miss to check out the similarities between c and c++. Let us now understand the Difference Between C And C++ without wasting time.

What Is The Difference Between C And C++?

C is a middle-level programming language that was invented by Dennis Ritchie. Whereas c++ is a high-level language that was invented by Bjarne Stroustrup. From here onwards you will get to study the difference between c++ and c language.

Basis Of DistinctionCC++
Type of programmingC is a function-oriented programming language.Whereas c++ is an object-oriented programming language.
Relationship It is a subset of c++ and cannot run c++ code.It is a superset of c and can run almost all c code.
Main FocusThey mainly focus on procedure instead of data.They mainly focus on data instead of procedure.
Keywords They support 32 keywords.They support 63 keywords.
ApproachIt usually follows a top-down programming approach.It follows a bottom-up programming approach.
File extensionIn c programming, the file extension is saved by “.c”.In c++ programming, the file extension is saved by “.cpp”.
Program divisionHere, a big program code is divided into small pieces known as functions.Here, a big program code is divided into objects and classes.
StructureGenerally, the structure in the c language doesn’t provide the feature of function deceleration.The structure in c++ language provides the feature of function declaring.
Standard i/o operationsIn c, scan and printf are used as standard input and output.In c++, cin>> and cout
Data securityThe data is not secured and can be accessed by external functions in the c programming language.The data is secured and cannot be accessed by external functions in the c++ language.
CompatibilityThey are not compatible with other programming languages.They are compatible with other generic programming languages.
Functions It does not support the functions with default arrangements.It supports the function with default arrangements.
Incline functionC does not support incline function.C++ do support incline function.
Ease of codingIn this language, users can modify and tell the program to do everything.This language only allows highly controlled object-oriented code.
Variable Users need to define the variables at the beginning of the program only.Users can declare the variables anywhere in the program.
Global VariablesIt allows multiple declarations of global variables.It does not allow multiple declarations of global variables.
Data typesC language support built-in and primitive data types.Whereas c++ language supports string and boolean data types.
Pointer This programming language only supports pointers.This programming language supports both pointers and references at the same time.
Focus pointIt only focuses on the steps that are used to solve the problem.It focuses on the object, not on the steps to solve the problem.
Exception Handling C language does not support exception handling by using some workarounds.C++ language support exception handling and is performed using try and catch block.
Overloading functionThis language does not allow users to use the overloading function.This language allows users to use the overloading function.
Namespace A namespace is absent in the c language.A namespace is present in the c++ language.
Source codeIt has free-format program source code.It is developed from the c language.
Encapsulation As data and functions are not encapsulated together, it does not support encapsulation.The data and functions are encapsulated together, so, it supports encapsulation.
Memory managementThey provide malloc and calloc functions for memory management.They provide a new operator for memory management.
Concept of mappingThe mapping between data and function is very complicated in the c language.The mapping between data and function can be easily established in the c++ language.

As now you have understood the difference between c and c++ syntax, let us compare it with java.

Difference Between C And C++ And Java

In this section, we will study c vs c++ vs java in detail.

Parameters CC++Java
TypeIt is a procedural programming language.It is an object-oriented programming language.It is a pure object-oriented programming language.
OriginThey are based on assembly language.They are based on the c language.They are based on both c as well as c++ languages.
Code ExecutionIt executes code directly.It executes code directly.It executes code via a java virtual machine.
Type of approachIt supports the top-down approach.It supports the bottom-up approach.It supports the bottom-up approach.
KeywordsThey support 32 keywords.They support 63 keywords.They support 50 defined keywords.
File generations This language generates .exe files.This language generates .exe files.This language generates .class files.

Difference Between C And C++ And Python

Thus, you must now be able to figure out the prime difference between c and c++ structure. Let’s compare these programming languages with python!

C++ Python 
It supports procedural programming language.It supports object-oriented programming language.It supports multiple programming languages like procedural, object-oriented, and functional programming languages.
Users might find difficulty in writing the code.As it is less complex than c, users can easily write the codes. Python is more complex than c++ but it easier to write the codes.
They support 32 keywords.They support 63 keywords.They support 33 keywords.
It provides malloc and calloc functions for memory allocation.It usually provides a new operator for memory allocations.The memory allocation and deallocation in python are automatic.
They do not support inheritance.They support both single and multiple inheritances.They support multiple inheritances including single, multiple, hierarchical, and hybrid inheritances.

Until now, we have studied the difference between c and c++ compilers. Over here, we will study the difference between c# and c++ language.

  • C# is a high-level programming language whereas c++ is a low-level programming language.
  • C# complies down to common language runtime, while c++ compiles down to machine code.
  • C# is a component-oriented programming language. However, c++ is an object-oriented programming language.
  • Generally, c# perfoms memory management automatically. In c++ language, users need to manually manage the memory.

Similarities Between C And C++

By now we have studied the difference between c and c++ with an example program. Let us learn its similarities.

  • Both the programming language has similar syntax.
  • The code structure of c and c++ languages are the same.
  • C and c++ have similar compilations.
  • Almost all c language codes are present in c++ language.
  • The basic grammar used in c and c++ language is the same.
  • The memory model of these programming languages is very similar.
  • Basic functions like stack, heap, file-scope and static variables are present in both programming languages.

FAQ

What Is The Difference Between C & C++?

The main difference between c and c++ is as follows.

  • C is a subset of c++ and c++ is a superset of c.
  • The c is a procedural programming language and c++ is an object-oriented programming language. 
  • The c language contains 32 keywords, while the c++ language contains 63 keywords.

Is C++ Better Than C?

For beginners, c++ is better than the c programming language. This is because it is loaded with more features, applications, and can be learned by anyone.

Is It Better To Learn C Or C++ First?

As both these languages are different, you can learn c language first. But the users who are familiar with object-oriented programming can go for c++ language before c. It is not compulsory to learn c before c++.

Is C Easier Than C++?

Yes, c is easier than c++ because it is a simple syntax with only 32 keywords. And also the data structures of the c language are easy to understand. 

Conclusion

In my above-written article, I have discussed the difference between c and c++ languages in detail. The primary difference between both these programming languages is that C is a subset of c++ and c++ is a superset of c. Even only 32 keywords are used in the c language while c++ contains 63 keywords. C is a procedural programming language and c++ is an object-oriented programming language. However, the basic grammar used in c and c++ language is nearly the same. Hence, you can write your own codes as you have learned the difference between c and c++.
