有关阶乘的循环

#include
int main()
{
  int i = 1;
  int n = 1;
  int jie = 1;
  int j = 1;
  int sum = 0;
  scanf("%d", &n);
  for (i = 1; i <= n; i++)
  {
    jie = jie * i;
    printf("%d的阶乘是：%d\n", i,jie);
    sum = sum+jie;
    }
  printf("n的阶乘是%d\n ", jie);
  printf("1！+2！+...+n!是%d\n", sum);
  return 0;
}
