Question

1． 先输入n，再输入n个实数并分别统计正数的和，负数的和，然后输出统计结果。

在TC上编程

Answer 1

我来帮你编写吧

#include "stdio.h"

main()
{
int n,b,i,j=0,k=0; //b表示我们要输入的整数,j是正整数的个数,k是负整数的个数;
printf("请输入一个大于0的整数");
scanf("%d",&n);
printf("请输入%d个整数",n);
for(i=0;i<n;i++)
{
scanf("%d ",&b);
if(b>0)j++; //如果输入的数大于0,刚j加1
else(b<0)k++; //如果输入的数小于0,刚k加1
}
printf("这n个数中有%d个正整数,有%d个负整数",j,k);
}

Answer 2

我刚学VB的
Private Sub Form_Load()
Dim n As Integer, s(1000) As Single, i As Integer, sumz As Single, sumf As Single
n = Val(InputBox("请输入实数总数", "输入框"))
For i = 0 To n - 1
s(i) = Val(InputBox("请输入第" & Str$(i) & "个实数", "输入框"))
Next
For i = 0 To n - 1
If s(i) > 0 Then
sumz = sumz + s(i)
Else
sumf = sumf + s(i)
End If
Next
Text1.Text = Str$(sumz)
Text2.Text = Str$(sumf)
End Sub
要先建立两个TEXT控件，一个command控件
