C program to find a^b

Below is the code to find power of a number

#include <stdio.h>
int main(){
    int a,b,res=1;
    printf("Enter base:");
    scanf("%d",&a);
    printf("Enter power:");
    scanf("%d",&b);
    if(b==0){
        printf("%d^%d is 1",a,b);
    }else{
       for(int i=1;i<=b;i++){
           res*=a;
        }
        printf("%d^%d is %d",a,b,res);
    }
    
}

Output:

Enter base:5
Enter power:2
5^2 is 25
