Why is my power operator (^) not working?

Question

#include 

void main(void)
{
    int a;
    int result;
    int sum = 0;
    printf(\"Enter a number: \");
    scanf(\"%d\", &a);
    for( int i =

pow() doesn't work with int, hence the error "error C2668:'pow': ambiguous call to overloaded function"

Write your own power function for ints:

int power(int base, int exp)
{
    int result = 1;
    while(exp) { result *= base; exp--; }
    return result;
}
