C 程序：使用递归计算N的幂

原文：https://www.studytonight.com/c/programs/recursion/power-of-n-using-recursion

下面是一个计算给定数字的结果的程序，使用递归上升到n的幂。

#include<stdio.h>

// function prototype declaration
int power(int n1, int n2);

int main()
{
    printf("\n\n\t\tStudytonight - Best place to learn\n\n\n");
    int base, exp;
    printf("Enter base number: ");
    scanf("%d", &base);
    printf("\n\nEnter Power factor: ");
    scanf("%d", &exp);
    printf("\n\n\n\t\t\t%d^%d = %d", base, exp, power(base, exp));
    printf("\n\n\t\t\tCoding is Fun !\n\n\n");
    return 0;
}

int power(int b, int e)
{
    if(e == 0)
        return 1;

    return (b*power(b, e-1));
}

输出:
