Question

Write a program (just console application, no GUI) in C# which prompts the user for an integer, increments the integer by 1 and displays the result in the following format: "The given number n has been incremented to n+1" Make sure your application fails to a secure mode. That is, no matter what is the user input, the application does not terminate with an error

Answer 1

using System;

public class IncrementInteger
{
    public static void Main(string[] args)
    {
        try
        {
            Console.Write("Enter an integer: ");
            int n = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("The given number " + n + " has been incremented to " + (n+1));
        }
        catch (Exception e)
        {
            Console.WriteLine("Invalid input.");
        }
    }
}
