how to write a program for raising a number to a power(integer only)
(e.g 2^2=4 ; 3^3=27 etc)
without using a precompiled C function(ie pow()). but only used addition, substraction, while loops,if statement and/or for loop.

#include <stdio.h>
int main(void)
{
This is just something I threw together in about a minute.
int main(void)
{
int base, power, index;
long answer;
base = 0;
power = 0;
answer = 1.00;
printf("Enter a base number: ");
scanf("%d", &base);
printf("Enter a power to raise the base to: ");
scanf("%d", &power);
for(index = 1; index <= power; index++)answer = answer * base;
printf("%d raised to the power of %d is %ld.", base, power, answer);}
getchar();
getchar();
return 0;
