I am absolute beginner in c#.
One of my firs lessons were making a simple calculator, and i am having problem with some code in it.
I think problem is in SWITCH loop.
namespace Calculator
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
double total1 = 0;
double total2 = 0;
private void btnOne_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnOne.Text;
}
private void btnTwo_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnTwo.Text;
}
private void btnThre_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnThre.Text;
}
private void btnFour_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnFour.Text;
}
private void btnFive_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnFive.Text;
}
private void btnSix_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnSix.Text;
}
private void btnSeven_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnSeven.Text;
}
private void btnEight_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnEight.Text;
}
private void btnNine_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnNine.Text;
}
private void btnZero_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnZero.Text;
}
private void btnClear_Click(object sender, EventArgs e)
{
txtDisplay.Clear();
}
string theOperator;
private void btnPlus_Click(object sender, EventArgs e)
{
total1 = total1 + double.Parse(txtDisplay.Text);
txtDisplay.Clear();
theOperator = "+";
}
private void btnEquals_Click(object sender, EventArgs e)
{
switch (theOperator)
{
case "+":
total1 = total1 + double.Parse(txtDisplay.Text);
break;
case "-":
total1 = total1 - double.Parse(txtDisplay.Text);
break;
case "*":
total1 = total1 * double.Parse(txtDisplay.Text);
break;
case "/":
total1 = total1 / double.Parse(txtDisplay.Text);
break;
}
txtDisplay.Text = total2.ToString();
total1 = 0;
}
private void btnPoint_Click(object sender, EventArgs e)
{
txtDisplay.Text = txtDisplay.Text + btnPoint.Text;
theOperator = ",";
}
private void btnMinus_Click(object sender, EventArgs e)
{
total1 = total1 + double.Parse(txtDisplay.Text);
txtDisplay.Clear();
theOperator = "-";
}
private void button2_Click(object sender, EventArgs e)
{
total1 = total1 + double.Parse(txtDisplay.Text);
txtDisplay.Clear();
theOperator = "*";
}
private void divideButton_Click(object sender, EventArgs e)
{
total1 = total1 + double.Parse(txtDisplay.Text);
txtDisplay.Clear();
theOperator = "/";
}
}
}
Thanks for help
