Question

Why do people use enums in C++ as constants when they can use const?

Answer 1

Enums are distinct types, so you can do type-oriented things like overloading with them:

enum Color { Red,Green,Blue };
enum Size { Big,Little };

void f( Color c ) {
}

void f( Size s ) {
}

int main() {
    f( Red );
    f( Big );
}
