求1+2！+3！+.......+n!
代码;
1 #include <stdio.h> 2 #include <stdlib.h> 3 4 /* run this program using the console pauser or add your own getch, system("pause") or input loop */ 5 void main(){ 6 7 int s;//和为s 8 int n; 9 scanf("%d",&n); 10 s=0;//给和赋初值为0 11 //二重循环循环遍历i,j 12 int i; 13 int j; 14 int t;//计算每个数阶乘的值 15 for(i=1;i<=n;i++){ 16 t=1; 17 for(j=1;j<=i;j++) 18 { 19 t=t*j; 20 } 21 s=s+t; 22 } 23 24 printf("和为%d",s); 25 } 26
