Used Function

1. #include<stdio.h>
2. void power(int,int);
3.  
4. void main() 
5. {
6.     int base, expo;
7.     printf("Enter the base : ");
8.     scanf("%d",&base);
9.     
10.     printf("Enter the exponent : ");
11.     scanf("%d",&expo);

16. void power(int base, int expo)
17. {
18.     int power=1;
19.     while(expo>0)
20.     {
21.         power=power*base;
22.         expo--;
