• • • • Write a program that should accept two numbers from the users and perform the following mathematical operations: Addition Subtraction Multiplication Division In case of division, an error message should be displayed if the second number is zero. (Duration: 35 min)


using System;

namespace Rohit{


    class Program{


static int res;
public static void addition(int a ,int b)
{
res = a+b;
Console.WriteLine("The sum of the two number entered is {0}",res);
}
public static void subtraction(int a ,int b)
{
res = a -b;
Console.WriteLine("The difference of the numbers entered is {0}",res);
}

public static void Multiplication(int a, int b)
{
res = a *b;
Console.WriteLine("The product of the two numbers entered is {0}",res);
}
public static void division(int a, int b)
{
if(b==0)
{
Console.WriteLine("You cannot divide by 0");
}
else
{
res = a / b;
Console.WriteLine("The division of the two numbers entered gives {0}",res);
}
}
static void Main(string[] args)
{
int Num1, Num2, ch;
string str1, str2, str3;
Console.WriteLine("Enter the first number:");
str1 = Console.ReadLine();
Num1 = Convert.ToInt32(str1);

Console.WriteLine("Enter the second number:");
str2 = Console.ReadLine();
Num2 = Convert.ToInt32(str2);

Console.WriteLine("Menu");
Console.WriteLine("1.Addition");
Console.WriteLine("2.Subtraction");
Console.WriteLine("3.Multiplication");
Console.WriteLine("4.Division");
Console.WriteLine("Enter the Operation you want to perform");
str3 = Console.ReadLine();
ch = Convert.ToInt32(str3);
switch (ch)
{
case 1:
addition(Num1, Num2);
break;
case 2:
subtraction (Num1, Num2);
break;
case 3:
Multiplication (Num1, Num2);
break;
case 4:
division (Num1, Num2);
break;
}
Console.ReadLine();
}
}
}
