Developers have been working with the C programming language since 1972. In 1979, the C++ extension was created. A good way to explain the new name is that the ++ character belongs to the C and C++ operators. This enables an incremental increase to be produced and “+1” is calculated with each run. So if you are familiar with C, you will understand that C++ is an extension of C. By the way, ++ can also be found in Java operators.
If you now want to indicate a new extension, you could simply add two plus signs to the end even though this makes no sense from a software programming point of view. This could also be the reason that the term C++++ has perhaps not become generally accepted and instead C# is used. But with a little imagination, C++++ can be found hidden within C#. If the plus signs are arranged in a square, this results in a sharp sign.
