Second Chance

Prime b

So this is my problem

Write a console-based program that prompts a user for
an hourly pay rate. If the user enters values less than $7.50
or greater than $49.99, prompt the user again. If the user
enters an invalid value again, display an appropriate error
message. If the user enters a valid value on either the
first or second attempt, display the pay rate as well as the
weekly rate, which is calculated as 40 times the hourly
rate.

My question is how do I prompt the user several times?

ohhh you right, because with || it just check one of the statements, while && check both statements! Got it.

The problem is this line:

if (inputNumber >= minPayRate || inputNumber <= maxPayRate) break;

The operator should be && not ||:

if (inputNumber >= minPayRate && inputNumber <= maxPayRate) break;

Vulpes this is what i have done, but when i run it goes straight to the 3rd Console.WriteLine.

double minPayRate = 7.5;
            double maxPayRate = 49.99;
            string stringInPutNumber;
            double inputNumber;
            int count = 0;

            while (true)
            {
             Console.WriteLine("Enter you hourly pay rate");
            stringInPutNumber = Console.ReadLine();
            inputNumber = Convert.ToDouble(stringInPutNumber);
            if (inputNumber >= minPayRate || inputNumber <= maxPayRate) break;
            count++;
            if (count == 2)
            {
                Console.WriteLine("Sorry, you had used your two tries to enter valid pay rate");
                return;
             }
            }
            Console.WriteLine("Hourly pay rate = {0: C}, weekly rate = {1: C}", inputNumber, inputNumber * 40);
            Console.ReadKey();

Try this:

using System;

class Program
{
static void Main()
{
int count = 0;
double rate = 0;

while (true)
{
Console.Write("Enter hourly pay rate : ");
rate = double.Parse(Console.ReadLine());
if (rate >= 7.5 && rate <= 49.99) break;
count++;
if (count == 2)
{
Console.WriteLine("Sorry, you've had your two chances to enter a valid pay rate");
return;
}
}

Console.WriteLine("Hourly rate = {0:C}, Weekly rate = {1:C}", rate, rate * 40);
Console.ReadKey();
}
}
