Difference Between C# and C++

Let us first learn about C# and C++ −

• C# is a general-purpose object-oriented programming language.
• It is considered as a pure object-oriented programming language.
• It is pronounced as 'C sharp'.
• It was developed by Anders Hejlsberg and his team at Microsoft.
• Memory Management is done automatically by the garbage collector.
• It is the language's duty to automatically delete the object once its objective is completed.
• It is windows specific, i.e. it can't be used on all systems.
• It doesn't support multiple inheritance.
• The pointers in C# can only be used in the unsafe mode.
• It is considered as a high-level language.
• Once the code is compiled, it gets converted into an intermediate language.
• It can be used to develop console applications as well as mobile and windows applications.
• It is easy to understand and work with, since it has a well-defined class hierarchy.
• Bound checking in an array data structure is performed by a compiler.
• Due to this, when a programmer tries to access an invalid array index, it results in a compilation error.

C++

• C++ is a statically typed, multi-paradigm language.
• It is also an object-oriented programming language.
• But it is not a purely object-oriented programming language since it has certain primitive data types.
• After the code is compiled, it gets converted into machine code, i.e low level language directly.
• Initially, it was known as C with classes. Later, it was changed to C++.
• It is pronounced as 'C plus plus'.
• It was developed by Bjarne Stroustrup at AT & T Bell Laboratories.
• Memory management in C++ is done manually by the programmer/developer. They create an object, and are totally responsible in using them and destroying them once its use is over.
• Platform Dependency: Code in C++ can be run on any platform.
• It is used where the application needs to interact with hardware directly.
• Multiple inheritance: C++ supports multiple inheritance with the help of classes. This means that once class can extend to more than one class at a point in time.
• C++ pointers can be used anywhere within the program.
• It is generally used to develop console applications.
• Bound checking is not done by compiler. When a programmer tries to access an invalid array index, it wouldn't result in a compilation error, it would just show the wrong output.

Let us now see the differences −
