HOWTO计算x的阶乘 [英] Howto compute the factorial of x

问题描述

如何获得一个整数值 X ，由 x所示！，它的产品数字1到x。

例如： 5！ 1x2x3x4x5 = 120。

  INT A，B = 1，C = 1，D = 1;
的printf（geheel getal X =）;
scanf函数（％d个，＆安培; A）;
的printf（％D =！，一）;
对于（B = 1; B＆LT = A; B ++）
{
     的printf（％d个X，C）;
     C ++;
     D = D * A;
}
的printf（=％D，D）;
 

解决方案

  

如何得到一个整数x，由x所示的索姆！是数字1至x的产物

您的意思是阶乘 x的？

修改 D = D * A; 到 D = D * B 内循环

how to get the value of an integer x, indicated by x!, it is the product of the numbers 1 to x.

Example: 5! 1x2x3x4x5 = 120.

int a , b = 1, c = 1, d = 1; 
printf("geheel getal x = ");
scanf("%d", &a);
printf("%d! = ", a);
for(b = 1; b <= a; b++)
{
     printf("%d x ", c);
     c++;
     d = d*a;
}
printf(" = %d", d);

解决方案

how to get the som of an integer x, indicated by x!, is the product of the numbers 1 to x.

Did you mean factorial of x ?

Change d = d*a; to d = d*b inside the loop
