从键盘上输入一个正整数N 求阶乘

Question

#include <stdio.h>
int fac( int n )
{ int i;
int t=1;
for( i=2;i<=n;i++)
t = t*i;
return (t);
}
int main()
{ int n;
int s;
printf("Enter an integer number:");
/************found************/
scanf(%d,&n);
s = fac(n);
/************found************/
printf("The result is : ____(2)____\n",s);
return 0;
}

Answer 1

scanf("%d",&n);//要加双引号
printf("The result is :%d\n",s);//整数输出。

Answer 2

return (t);-->return t;
