Difference Between C++ and C# (With Table)

The computer is used in almost all of the activities taking place. To make changes and innovation in computers, a person needs to be a programmer; to understand the computer language and write it.

Programming is a course under which a person learns one or several computer languages. The choice is yours which language you want to learn. There are various computer languages such as java, C#, C+, python, etc. C++ and C# both are the most common and important computer languages and also are the extension of the C language.

Most people get confused between those and find it difficult to choose between both the language. To terminate this, this article has all the differences between C++ and C# so that it’ll be easier for everyone to choose the best language according to them.

C++ vs C#

The difference between C++ and C# is that C++ is not perfectly object-oriented while C# is Object programming. They also have a difference in terms of their features, such as memory management, platform Dependency, Multiple Inheritance, Bound Checking, Pointer, compilation, application, and many more.

C++ is a middle-level programming language and is an extended version of a low-level C programming language that has additional features. It has several advantages that include portability or platform independence, multi-paradigm, memory management, low-level manipulation, large community support, scalability, and, last but not least, compatibility with the C programming language.

C# is also a programming language and is an extended version of the C programming language that runs on the .Net framework. It is also an enhanced version of the C++ programming language. It has several advantages that include object-oriented, cross-platform, automatic garbage collection, avoiding the problem of memory leak, better integration, cost-benefit, programming support, etc.

Comparison Table Between C++ and C#

Parameters of ComparisonC++C#
Memory ManagementIt is performed manually.It is performed automatically.
Platform DependencyCode can be run on any platform.Code is windows specific.
Multiple InheritanceIt supports multiple inheritances.Do not spend multiple inheritances.
Bound CheckingNot performed by the computer.Performed by compiler
PointersCan be used anywhere in programs.Can only be used in unsafe mode only.

What is C++?

C++ language was developed by Bjarne Stroustrup, a Ph.D. student of Denmark, to improve the already existing C programming language by adding some new features in it. It is an intermediate-level programming language due to its derivation from a low-level language. All technical and commercial software can be developed with these programming languages.

Following are some facts about the C++ language:

  • It introduces object-oriented programming from the Simula67 Programming language. 
  • It supports primary features such as abstraction, polymorphism, encapsulation, and inheritance of object-oriented programming.
  • The minimum requirement to run a C++ program is a function.
  • It was invented at American Telephone & Telegraph, bell laboratories, in the U.S.A.
  • It can also be written without using classes.
  • Most of the new languages are influenced by it.
  • It supports several programming styles.

Although this has various advantages as mentioned above, still it has all the following disadvantages:

  • It is an 8-bit program only.
  • During high-level programming, it becomes more complex.
  • It does not support garbage pickup, Dynamic Memory Allocation, threads built-in.
  • It is not fully secured due to its pointer and global variable.
  • It is not used for the platform-dependent app.

What is C#?

C# also called C Sharp, is a high-level programming language derived from the low-level C programming language and developed by Anders Hejlsberg, a leader of a team of Microsoft in 2002. It compiles into byte-code. Following are some of the facts related to C# are:

  • The name is stimulated by the musical notation.
  • The name C# was first used in 1988 by the Microsoft team.
  • It is similar to another C-style family language, for example, Java and C++.
  • It is used for embedded systems to write the application.
  • It is suitable for developing games, web pages, android applications, Windows store app, etc.
  • Contains the highest class that supports Generics and Templates and internalization.
  • It has a native garbage collection.
  • Offers Standard Library
  • Assembly Versioning
  • Conditional Compilation
  • Simple Multithreading
  • Lambda and LINQ Expressions
  • Integration with Windows

Disadvantages of C# programming languages:

  • It has a poor x-platform GUI.
  • The server running the application of the system must be windows based.
  • It is less flexible as compared to other languages.

Main Differences Between C++ and C#

  1. They both are different in terms of memory management. In C++, it is performed by the programmer manually. He is responsible for deleting the object he earlier created for some task, while in C#, this is done by the garbage collector automatically. The garbage collector is responsible for deleting the object created by the programmer for some task.
  2. C++ has an advantage as it can be used on any platform, while C# can only be used on Windows.
  3. Multiple Inheritances is supported by C++ but not by the C#.
  4. Bound Checking by the compiler is not supported in C++, while in C# bound checking is performed by a compiler.
  5. The pointer can be used by the programmer anywhere in C++ while it can only be used in an unsafe mode in C#.
  6. As both of them are an extended version of a low-level programming language, but C++ is a middle level, and C# is a high-level programming language.
  7. C++ is comparatively difficult and more complex to use, whereas C# is easier due to its well-defined hierarchy classes.
  8. After compilation, C++ code directly converts into machine code while C# code converts into an intermediate language.
  9. C++, due to its primary data types, is not purely object-oriented programming, while C# is purely Object-oriented programming.


Therefore, now no one should be confused between C++ and C#. They have a similarity in that both of them are extensions and updates of the former programming languages C. It is the oldest programming language invented in 1972 by Dennis Ritchie and was published after six years in 1978. it is the most used language worldwide till now. It is mostly used by programmers in operating systems and applications that require older code.

It is recommended most to the new programmers as most of the new programming languages are derived from it only. It is also more secure due to its age.
