    Just loop n times and multiply val by itself:
    Code:
    int power ( int val, int n )
    {
      int ret = 1;
    
      for ( int i = 0; i < n; i++ )
        ret *= val;
    
      return ret;
    }
    -Prelude
    My best code is written with the delete key.

    There is a function called exp();. This is found in math.h. The syntax is
    exp(number,power);

    I know this isn't a for loop, but it is a differrent method.
