好像用不着access2003吧
vb代码:
Private Sub Command1_Click()
Dim r As Single
Dim c As Single
Dim s As Single
Dim P As Single
P = 3.14
r = Int(Text1.Text)
c = 2 * P * r
s = 2 * P * r
Label1.Caption = "圆周长为 : " + Str(c)
Label2.Caption = "圆面积为 :" + Str(s)
End Sub
程序中有一个文本框text1 两个Label控件 分别是Label1,Label2

也不知道你是要什么语言的,给你几种吧
1.VB的
'在代码窗口中直接复制代码
Private Sub Form_Load()
Dim Radiu As Single '半径
Dim Area As Single '面积
Dim Circumference As Single '周长
Const Pi As Single = 3.141592653
Radiu = InputBox("请输入半径:", "输入")
Area = Pi * Radiu * Radiu
Circumference = 2 * Pi * Radiu
MsgBox "你输入的数是" & Radiu & vbCrLf & _
"面积是" & Area & vbCrLf & _
"周长是" & Circumference, vbInformation, "输出"
End
End Sub
2.C++的
#include
using namespace std;
int main()
{
float radiu=0, area=0, circumference=0;
const float pi = 3.14159;
cout<<"请输入半径:";
cin>>radiu;
area = pi * radiu * radiu;
circumference = 2 * pi * radiu;
cout<<"你输入的半径是"<
