Question

VB编程:计算1！+3！+5！+7！+9！用循环结构怎么做？要详细过程

Answer 1

这里只能给出伪宏租宏代码了，型者VB没蔽册学过，假设是算到n的阶乘。
sum = 0;
fac = 1;

for (i = 1; i <= n; i++) {
fac = fac * i;

if (i mod 2 == 0) continue;

sum = sum + fac;
}

Answer 2

vb的代码如睁册下：段顷计算到9！
Dim i, j As Integer
Dim s1 As Double
Dim s2 As Double

s2 = 0
For i = 1 To 9 Step 2 '1,3,5,7,9
s1 = 1
For j = 1 To i '悉燃宏1,3,5,7,9 !
s1 = s1 * j
Next j
s2 = s2 + s1
Next i

MsgBox s2 '输出结果 368047

Answer 3

Private Sub Command1_Click()
Dim i As Integer, j As Integer
Dim x As Long, y As Long
x = 1
For i = 1 To 9 Step 2
For j = 1 To i
x = x * j
Next
y = y + x
x = 1
Next
MsgBox y

End Sub
