Console Readline

Console Programs

Here we are going to learn how to make some console program. In the previous blog we studied about how to make a very short console program.CLICK HERE to see it again. Now we are going to discuss some concepts of previous console program.

       We have seen Console.WriteLine() method. In it Console is a class and "WriteLine" is an method of that class. So we have a clear concept to how to write in the console but if we want a program which calculate the sum of two  number then how we can do that?

            How we can read the number from Console? There is lot methods but here we are going to use Console.ReadLine() method. We will use like

int x = Console.Readline();

NO!! the above syntex genrate an error because it return the value in the form of string so we need to convert the string value to the int value and How we shall do that?

int x = Convert.ToInt32(Console.ReadLine());

CONSOLE PROGRAM:-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Enter the first number!");
            int x = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter the second number!");
            int y = Convert.ToInt32(Console.ReadLine());
            int z = x + y;
            Console.WriteLine("Result of the sum is");
            Console.WriteLine(z);
           
        }
    }
}
