c语言编程练习

使用for循环计算阶乘之和

#include
int main()
{
	int i,j;
	double factorial,s=0;
	for(i=0;i<=10;i++)
	{
		factorial=1;
		for(j=1;j<=i;j++)
		   factorial=factorial*j;
		   s=s+factorial;
	}
	printf("1!+2!+3!+4!+5!+6!+7!+8!+9!+10!=%.0f",s);                                               
 } 

运行结果

1!+2!+3!+4!+5!+6!+7!+8!+9!+10!=4037914
