Math Operations With Logical Operation Using C#

I have shown how you can perform math as well as logical operations together.

So first we will create a new windows application and design the below form.


Now use the below code,

  1. using System;    
  2. using System.Collections.Generic;    
  3. using System.ComponentModel;    
  4. using System.Data;    
  5. using System.Drawing;    
  6. using System.Linq;    
  7. using System.Text;    
  8. using System.Threading.Tasks;    
  9. using System.Windows.Forms;    
  10.     
  11. namespace Example_of_math_variables_and_if_statements    
  12. {    
  13.     public partial class Form1 : Form    
  14.     {    
  15.         private string x; //This defines the string variable x    
  16.         private string y;    
  17.         private string random_string;    
  18.         private int x_number; //This defines the integer variable x_number    
  19.         private int y_number;    
  20.         private int random;    
  21.         public Form1()    
  22.         {    
  23.             InitializeComponent(); //This creates the window from the information that was entered in the form designer    
  24.         }    
  25.         private void radioButton1_CheckedChanged(object sender, EventArgs e)    
  26.         {

  30.             {

  32.             }

  39.             random = x_number + y_number; //This sets the integer variable random to the value of x_number plus y_number    
  40.             random_string = Convert.ToString(random); //This converts the integer random to the string random_string    
  41.             this.label3.Text = random_string;    
  42.         } //This method is called when the radiobutton (a button that when pressed makes every other radiobutton in its groupbox not pressed) is changed

In the above code I have performed all the math as well as logical operations.
