C Program to find N power of M (Exponentiation) without using predefined function

Description

Get two inputs  num1 and num2, compute the exponentiation of base num1 and power num2 without using  predefined funtions
Input:
2 4
Output:
16

Solution

#include<stdio.h>
int main()
{
	int num1,num2,product=1;
	printf("Enter base and power value:");
	scanf("%d %d",&num1,&num2);
	while(num2>0)
	{
		product=product*num1;
		num2--;
	}
	printf("%d",product);
	return 0;
}
