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));
        return 1;


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

You can also compute the power of a number using a loop.


If you need to calculate the power of a number raised to a decimal value, you can use the pow() library function.
