Question

C语言编程题。编程题目为 编程计算1!+2!+3!+……+10!的值

把详细步骤一步步写出来，要正确地，谢谢

Answer 1

#include<stdio.h>
void main()
{
int i,j,n,sum;

sum = 0;
for(i=1;i<=10;i++)
{
n = 1;
for(j=1;j<=i;j++)
{
n=n*j;
}
sum = sum + n;
}
printf("%d",sum);

}

Answer 2

#include<stdio.h>
void main()
{
int i,j,t=1,s=0;
for (i=1;i<=10;i++)
{
t=t*i;
printf("%d+",t);
s=s+t;
}
printf("\b=%d\n",s);
}

Answer 3

main()
{
long i,n=1,sum=0;
for(i=1;i<=10;i++)
{
n*=i;
sum+=n;
}
printf("%ld\n",sum);
}

Answer 4

main()
{
int i,j,n,sum=0;
for(i=1;i<=10;i++)
{
n=1;
for(j=1;j<=i;j++)
n*=j;
sum+=n;
}
printf("%d\n",sum);
}

Answer 5

int x = 1;
for (int i=2; i<10; ++i)
{
x*=i;
}
printf("1*...*10 = %d", x);
