Proposed exercise
Write a program which asks the user for two numbers and an operation to perform on them (+,-,*,x,/) and displays the result of that operation, as in this example:
Enter first number: 5
Enter operation: +
Enter second number: 7
5+7=12
Note: you MUST use "switch", not "if"
Output
Solution
using System;
public class CalculatorSwitch
{
public static void Main()
{
int a, b;
char operation;
Console.Write("Enter first number: ");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter operation: ");
operation = Convert.ToChar(Console.ReadLine());
Console.Write("Enter second number: ");
b = Convert.ToInt32(Console.ReadLine());
switch (operation)
{
case '+':
Console.WriteLine("{0} + {1} = {2}", a, b, a+b);
break;
case '-':
Console.WriteLine("{0} - {1} = {2}", a, b, a-b);
break;
case 'x':
case '*':
Console.WriteLine("{0} * {1} = {2}", a, b, a*b);
break;
case '/':
Console.WriteLine("{0} / {1} = {2}", a, b, a/b);
break;
default:
Console.WriteLine("Wrong Character");
break;
}
}
}
