3.05 - Calculator - if

Objetive
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 "if", not "switch"


Solution
using System;
public class exercise056
{
    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());
        
        if (operation=='+')
            Console.WriteLine("{0} + {1} = {2}", a, b, a+b);
        else if (operation=='-')
            Console.WriteLine("{0} - {1} = {2}", a, b, a-b);
        else if ((operation=='x') || (operation=='*'))
            Console.WriteLine("{0} * {1} = {2}", a, b, a*b);
        else if (operation=='/')
            Console.WriteLine("{0} / {1} = {2}", a, b, a/b);
        else
            Console.WriteLine("Wrong Character");
    }
}
