C# vs C++: Difference Between Them

Key Difference Between C# and C++

  • C++ is a low level programming language that adds object-oriented features to its base language C whereas C# is a high level language.
  • C++ compiles down to machine code whereas C# ‘compiles’ down to CLR (Common Language Runtime), which is interpreted by JIT in ASP.NET.
  • C++ is an object-oriented language while C# is considered a component-oriented programming language.
  • In C++ you need to manage memory manually whereas C# runs in a virtual machine, which performs memory management automatically.
  • In C++ development should follow any specific architecture and must be portable whereas C# development should be simple, modem, general-purpose, object-oriented programming language.

What is C++?

C++ is a computer programming language that contains the feature of C programming language as well as Simula67( a first object Oriented language). C++ introduced the concept of Class and Objects.

It encapsulates high and low-level language features. So, it is seen as an intermediate level language. Earlier it was called “C with classes” as it had all the properties of the C language.

What is C#?

C-Sharp is an object-oriented programming language developed by Microsoft that runs on .Net Framework. It has features like strong typing, imperative, declarative, object-oriented (class-based), and component-oriented programming. It was developed by Microsoft within the .NET platform.

The name “C sharp” was inspired by musical notations. Here ‘#’ symbol indicates that the written note must be made a semitone higher in pitch.

History of C++

C++ language was developed by Bjarne Stroustrup at AT & T Bell Laboratories. Stroustrup was a strong supporter of C an admirer of Simula67. He wanted to combine the best of both the languages. He was aiming to create a language which supports object-oriented programming features and still retains the power of C. This resulted in C++.

History of C#

Anders Hejlsberg is the key contributor to C# language development. In 1999, he built a team to develop a new language which was then called “Cool.”. The project was approved and announced in July 2000 at the .Net Developers Conference. The language was later renamed as C#.

Principles of C++ development

  • The program should be simple, object-oriented and easy to understand
  • Development should be conducted in the robust and secure environment.
  • Code should follow specific architecture and must be portable.
  • Code should be easily “interpreted and dynamic “

Principles of C# development

  • It should be simple, modem, general-purpose, object-oriented programming language.
  • The language and implementations should provide support for software engineering principles
  • C# is an ideal choice for building applications for both hosted and embedded systems.

Now in this C# vs C++ tutorial, let’s understand the key differences between C Sharp vs C++.

Difference between C++ and C#

Following is the main difference between C# and C++:

C++ Vs C#
C++ Vs C#
Parameter C++ C#
Type of language C++ is a low level and platform neutral programming language. C# is a high-level language.
Compiling C++ compiles down to machine code C# ‘compiles’ down to CLR (Common Language Runtime), which is interpreted by JIT in ASP.NET
Memory management In C++, you need to manage memory manually if you dynamically allocate object. C# runs memory management automatically
Multiple inheritances C++ support the multiple inheritances C# does not support multiple inheritances.
Level of difficulty C++ includes more complex features. C# doesn’t have any complex features. It has a simple hierarchy and quite easy to understand.
Default access Specifier Public in C++ for Struct. Private for classes Private in C# .net.
Platform C++ is a language that runs on all sorts of platforms. It is also equally popular on Unix and Linux systems. C#, while standardized, is rarely seen outside windows.
Standalone applications C++ can create standalone applications. C# can’t make a standalone application.
Object Oriented C++ is not a complete object orient language. C# is a pure object-oriented language.
Bound checking Does not support bound checking of arrays. Supports bound checking of arrays.
Garbage Collection C++ does not support garbage collection. C# supports garbage collection.
Multiple inheritance C++ supports multiple inheritance. C# does not offer multiple class inheritance.
Foreach Loop Older version of C++ does not support for each loop. (Range-based for loop in C++ is added since C++ 11) C# supports for each loop.
Use of pointers You can use pointers anywhere in the program. You can use pointer only in the unsafe mode.
Used for Widely used in gaming. C# programming can be used to create Windows, mobile, and console applications.
Size of binaries C++ is much more lightweight. C# has a lot of overhead and libraries should be included before it will compile.
Type of Projects C++ programmers generally focus on applications that work directly with hardware or that need better performance than other languages can offer. C# is used for modern app development.
Compiler warnings C++ allows you to do almost anything provided the syntax is right. Therefore, it is flexible language, but you may cause serious damage running OS. C# is highly protected. as it Compiler will throw errors and warnings in case you inadvertently write code that can cause damage.
Compilation result After compiling, C++ code is converted into machine code. After compiling, C# code is converted into an intermediate language code.
Switch statement In C++ Switch Statement, the test variable can’t be a string. In a C# switch statement, may or may not be a string.
