C program to calculate the power using recursion

In this example, you will learn to calculate the power of a number using recursion.


Program to calculate power using recursion


#include <stdio.h>
int power(int n1, int n2);
int main(){
    int base, a, result;
    printf("Enter base number: ");
    scanf("%d", &base);
    printf("Enter power number(positive integer): ");
    scanf("%d", &a);
    result = power(base, a);
    printf("%d^%d = %d", base, a, result);
    return 0;
}

int power(int base, int a){
    if (a != 0)
        return (base * power(base, a - 1));
    else
        return 1;
}

Output

Enter base number: 3
Enter power number(positive integer): 4
3^4 = 81
