兄弟，你的问题大有学问呀
佩服！！！！！！！！！！！！！！！！！！！！！！

overcome2007-11-04 17:18

有空再想想

这个好像不是很难呀

你自己好好想下就会啦

思路是这样的
给分母一个变量
然后求这个变量阶乘
就行啦

你把他变成n!+(n-1)!+...+2!+1/n!再试试

8楼的正确

#12

bkillbelong2007-11-05 00:02

8楼的少加了个1,sum应该赋初值为1

for循环:
for(i=1;i<=101;i++){
tmp=1;
for(k=1;k<=i;k++) tmp*=k;
result+=1/temp;
}

while循环:
i=1;
while (i<=101){
tmp=1;k=1;
while(k<=i){
tmp*=k;
}
result+=1/tmp;
}

Dim x, y, z As Integer
Dim a, b, c As Double
Dim temp, sum As Double
sum = 0

For x = 0 To 101
temp = 1
If x = 0 Then
temp = 1
b = 1
Else
For y = 1 To x
temp = temp * y
Next
b = x / temp
End If

sum = sum + b
Next

Me.c.Text = sum

vb.net作的！！！！！！！！

程序对错先不说,只说思想就大大有问题~!
还有,你的软件开发人员的开发规则都不知道么?
程序的格式都是些垃圾代码~还有几乎所有的表示符都是无意义的垃圾变量标识符.

好像有公式吧
