namespace Calculation
{
public partial class Form1 : Form
{
int number1, number2;
bool check1, check2;
String text1, text2;
public Form1()
{
InitializeComponent();
}
private void add_btn_Click(object sender, EventArgs e)
{
text1 = num1.Text;
check1 = int.TryParse(text1,out number1);
text2 = num2.Text;
check2 = int.TryParse(text2,out number2);
if (check1 == false || check2 == false || (number1 < 0 || number2 < 0))
{
result.Visible = true;
result.ForeColor = Color.Red;
result.Text = "Value must be numeric and > 0";
}
else
{
int res=number1+number2;
result.Visible = true;
result.ForeColor = Color.Yellow;
result.Text = res.ToString();
}
}
private void multiply_btn_Click(object sender, EventArgs e)
{
text1 = num1.Text;
check1 = int.TryParse(text1, out number1);
text2 = num2.Text;
check2 = int.TryParse(text2, out number2);
if (check1 == false || check2 == false || (number1 < 0 || number2 < 0))
{
result.Visible = true;
result.ForeColor = Color.Red;
result.Text = "Value must be numeric and > 0";
}
else
{
int res = number1 * number2;
result.Visible = true;

result.Text = res.ToString();
}
}
