Answer 1

What is the exact meaning of “int const* ” in C?

It means a pointer to a constant integer. In other words, the pointer is not constant, but the value it points to is.

And also a small comparison between “const int*” and “int const*”

There is no difference.

A similar construct is int * const. Here there is a difference. This time the pointer is constant but the value it points to is not.
