用visualstudio制作的简单的计算器

1、用 visual计算器。studio制作的简单的首先利用visual studio 里面的button 和textbox 模块建立上图模块。然后就是编写程序：该程序最重要的是要理解清楚计算器的运算逻辑。public partial class Forml : Form stri ng a, b, q, ac;int c = 0, d = 0, n = 0, p = 0, m = 0;double temp1 = -1;int pos = 0;public Form1()object sender,InitializeComponent();private void textBox1_TextC

2、hanged(EventArgs e)public void addNum(int num)textBox1.Text = textBox1.Text +/num.ToString();if (c 0)加？减？乘?除y运?算?a = num.ToString();b = b + a;textBox1.Text = b;private void button1_Click( object sender, EventArgs e)addNum(7);/向一 显？示o?屏加？字d?n+;sender,sender,private void button2_Click( objectEventArgs

3、 e)addNum(8);private void button3_Click( objectEventArgs e)addNum(9);sender,sender,EventArgs e)addNum(4);private void button6_Click( objectEventArgs e)addNum(5);private void button7_Click( objectEventArgs e)addNum(6);sender,sender,sender,EventArgs e)addNum(1);private void button10_Click( object Even

4、tArgs e)addNum(2);private void button11_Click( object EventArgs e)addNum(3);private void button14_Click( object EventArgs e)addNum(0);private void button15_Click( object sender, EventArgs e)if (p=0)textBoxl.Text = textBoxl.Text +. ; / 加口？p+;m+;if (c 0)Oa加？减?乘？除y运？算?private void button4_Click( object

5、 sender,EventArgs e)pos = 1;temp1 = Convert .ToDouble (textBox1.Text); textBox1.Text =temp1+ + ;d+;c+;p = 0;private void button8_Click( object sender,EventArgs e)pos = 2;temp1 = Convert .ToDouble(textBox1.Text);textBox1.Text = temp1 + - ;c+; p = 0; private void button12_Click( object sender,EventArg

6、s e)pos = 3;temp1 = Convert .ToDouble(textBox1.Text); textBox1.Text = temp1 +c+; p = 0;private void button16_Click( object sender,EventArgs e)pos = 4;temp1 = Convert .ToDouble(textBox1.Text);textBox1.Text = temp1 + / ;c+; p = 0;private void button13_Click( object sender,EventArgs e)double temp2 = Convert .ToDouble(b);switch (pos)case 1:textBox1.Text = (temp1 +temp2).ToString();break ;case 2:textBox1.Text = (temp1 - temp2).ToString();break ;case 3:textBox1.Text = (temp1 * temp2).ToString();break ;case 4:textBox1.Text = (temp1 /temp2).ToString();break ;private void button17_Click( obje
