求S=1+1/1!-1/2!+1/3!-1/4!......+1/9!的值怎么编写程序 求求各位大虾 帮我做出来吧 我马上就要交作业了

Private Sub Form_Click()
s = 1
For i = 1 To 9
s = s * i
If i Mod 2 = 0 Then
sum1 = sum1 - 1 / s
Else
sum2 = sum2 + 1 / s
End If
Next i
Sum = 1 + sum1 + sum2
Print Sum
End Sub

#include <math>

using std::pow;

double func(int n)
{
int i=1;
double result=0,j=1.0;
result+=i;
for(;i<=n;i++)
{
j*=n;
result+=pow(-1,n+1)/j;
}
return result;
}
