求1+2！+3！+.......+n!

代码;

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */
void main(){
    
    int s;//和为s 
    int n;
    scanf("%d",&n);
    s=0;//给和赋初值为0 
    //二重循环循环遍历i,j 
    int i;
    int j;
        int t;//计算每个数阶乘的值 
    for(i=1;i<=n;i++){
        t=1;
        for(j=1;j<=i;j++)
        {
            t=t*j;
        } 
        s=s+t;
        }
    
        printf("和为%d",s);
