Hi:) , I need good and briefly explaination of those questions here.

Language C++

_Can you name any differences between Python and C++ as programming languages? _In C++ you have to specify the type of variables. Are there any benefits to it? _What is a compiler? _What is a reference variable? _What is a pointer? _How to create comments in C++? _What does it mean that a function has return type void? _How is a function with the signature void print(int) used? _What does it mean that a function returns the type int&?

Thank you inavance
