Description

Raises numbers to integer powers

Demo Code

#include <stdio.h>

double power(double n, int p); // ANSI prototype

int main(void)
{
    double x, xpow;
    int exp;//from   w w  w .  ja v  a 2s. com
    
    printf("Enter two numbers. Enter q to quit.\n");
    while (scanf("%lf%d", &x, &exp) == 2){
        xpow = power(x,exp);   // function call
        printf("%.3g to the power %d is %.5g\n", x, exp, xpow);
        printf("Enter next pair of numbers or q to quit.\n");
    }
    printf("from b ook2s.com!\n");
    
    return 0;
}

double power(double n, int p) {
    double pow = 1;
    int i;
    
    for (i = 1; i <= p; i++)
        pow *= n;
    
    return pow;                // return the value of pow
}
