Hi there,

I am new to c#, I have written this code that calculates number of days out of number of hours. But the problem is when I input 25 hours, the value in the hours field is saved as 50 i.e. double of the actually entered value. Can someone help me about this.

  int hours, numberOfDays = 0;

            Console.WriteLine("Please enter number of hours => ");

            hours = Convert.ToInt32(Console.Read());

            numberOfDays = hours/24;

            int hoursLeft = hours%24;


            Console.WriteLine("Number of days => {0}", numberOfDays);

            Console.WriteLine("Number of hours left => {0}", hoursLeft);

            Console.ReadKey();

Try int.Parse instead Convert.ToInt32 .. should not make a difference.. but just to make sure.

Normally, I do this:

hours = int.Parse(Console.ReadLine());

I used to convert strings this way though:

string response;

int hours;

response = Console.ReadLine();

hours = Convert.ToInt32(hours);

This is all assuming if the source of your problem is when the conversion takes place...

EDIT: Just to note, this is what the documentation for the Console.Read method says:
"Reads the next character from the standard input stream."
I would use Console.ReadLine just in case.

Use the Console.Read() returns an int value so you don't need to call Convert.ToInt32(). Change your code to use Console.ReadLine() and life will be good.

    public static void Main(string[] args)

    {

      int i = Console.Read();

      System.Diagnostics.Debugger.Break(); //i = 50 if you key "25" then <enter>

    }
