Question

For example when I input 2 for num1 and 3 for num2, I expect to get 8 for the output as soon as I enter the second number. However, the program expects me to input one more integer, and I just input a random number like 242 and it still outputs 8, which means that it does not affect the result. So my question is why is there the third input?
Thank you for your help!

#include "stdafx.h"

int Power (int num1, int num2);

int main ()
{
    int a, b;
    puts ("Enter two numbers, a and b:\n");  
    scanf ("%i\n", &a);
    scanf ("%i\n", &b);
    printf ("%i\n", Power(a, b));
    return 0;
}

int Power (int num1, int num2)
{
    int sum=1;
    for (int i=1; i<=num2; i++){
        sum= sum*num1;
    }
    return sum;
}

Get rid of the newlines: \n, in your scanf format strings, or just use a single scanf, e.g.:

scanf("%i%i", &a, &b);

Or:

scanf ("%i", &a);
scanf ("%i", &b);
