    problem with exponentiation

    i got a problem with exponentiation(< i think its called that in english XD)

    Code:
    int b = 1;
    
    int a() {
         return 600 ^ ((double)b / 100 + 1);
    }
    gives me this error in visual c++:

    Code:
    expression must have integral or enum type

    That is because ^ is the bitwise excluside or operator, not exponentiation.

    You could #include <cmath> and use std::pow instead.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
