C# Sharp Exercises: A menu-driven program for a simple calculator

C# Sharp Conditional Statement: Exercise-25 with Solution

Write a program in C# Sharp which is a Menu-Driven Program to perform a simple calculation.

Sample Solution:-

C# Sharp Code:

using System;  
public class Exercise25  
{  
    public static void Main() 
   {
  int num1,num2,opt;

           Console.Write("\n\n");
           Console.Write("A menu driven program for a simple calculator:\n");
           Console.Write("------------------------------------------------");
           Console.Write("\n\n");


  Console.Write("Enter the first Integer :");
  num1 = Convert.ToInt32(Console.ReadLine());
  Console.Write("Enter the second Integer :");
  num2 = Convert.ToInt32(Console.ReadLine());

  
    Console.Write("\nHere are the options :\n");
    Console.Write("1-Addition.\n2-Substraction.\n3-Multiplication.\n4-Division.\n5-Exit.\n");
    Console.Write("\nInput your choice :");
    opt = Convert.ToInt32(Console.ReadLine());

    switch(opt) {
      case 1:
        Console.Write("The Addition of  {0} and {1} is: {2}\n",num1,num2,num1+num2);
        break;
        
      case 2:
        Console.Write("The Substraction of {0}  and {1} is: {2}\n",num1,num2,num1-num2);
        break;
        
      case 3:
        Console.Write("The Multiplication of {0}  and {1} is: {2}\n",num1,num2,num1*num2);
        break;  
      
      case 4:
        if(num2==0) {
          Console.Write("The second integer is zero. Devide by zero.\n");
        } else {
          Console.Write("The Division of {0}  and {1} is : {2}\n",num1,num2,num1/num2);
        }  
        break;
        
      case 5: 
        break; 
        
      default:
        Console.Write("Input correct option\n");
        break; 
    }
  }
}
