C语言实现求阶乘和阶乘的和：

#include<stdio.h>
int getMul(int n){			//递归调用计算阶乘!n int mul=1;if(n==1){mul==1;return mul;}else{mul=n*getMul(n-1);return mul;}
}int getSum(int n){			//求阶乘的和 int sum=1;if(n==0){sum=0;}else{sum = getMul(n)+getSum(n-1); }return sum;
}int main(){int n,h,s;printf("please input n：");scanf("%d",&n);printf("!n=%d\n",getMul(n)); printf(" s=%d\n",getSum(n)); 
}

运行结果：
