Agh, okies I'm trying to loop my if statement, which loop should I use?

if (Tnumber > 25)
{
Console.Write("Invalid input!\n\nPlease enter a table number between 1 and 25: ");
Tnumber = Int32.Parse(Console.ReadLine());
}
Basically what the objective is, that if the user keeps entering a value higher than 25 it should continue to show that message until such time that a value below 25 is entered.. also whilst I'm asking... Can you also tell me how do I add another clause so that anything but the numbers between 1 and 25 also returns the same error message.

Thanks =)

Hi Black_Rose,

I guess you can better use do...while loop

something like below:

...
do{
if (Tnumber > 25)
{
Console.Write("Invalid input!\n\nPlease enter a table number between 1 and 25: ");
Tnumber = Int32.Parse(Console.ReadLine());
} 
else
{
Console.Write("Invalid input!\n\nPlease enter a table number between 1 and 25: ");
break;

} 
}while(Tnumber > 0)  // or condition that proves that user has input a number.

Hope I understood your problem and have answered well. 😀

Shalini, that's absolutely perfect thank you. I attempted the do while loop, but messed it up somehow :S I've changed the following on your code:

else
{
Console.Clear ();
break;
}
Just so when I'm done it clears the screen and displays new information.

Okay this is another part I'm struggling to understand. I'm asking the user to code in p for pizza and d for drinks. If it's a p then a pizza menu will show up if d is typed in than a drinks menu. How do I assign the 'd' and 'p' to show their respective menus? I've done the following:

Console.WriteLine("\n\n\t\t\tPlease enter which menu you would like to order from: \n\n\t\t\t\t1) Type 'p' for Pizza \n\n\t\t\t\t2) Type 'd' for Drinks\n");
Console.ReadLine();
=)

Hi Black_Rose,

I am not sure whether you tried something like following:

Console.WriteLine("\n\n\t\t\tPlease enter which menu you would like to order from: \n\n\t\t\t\t1) Type 'p' for Pizza \n\n\t\t\t\t2) Type 'd' for Drinks\n");
 
// assigns whatever user enters to a variable menuSelectOption
String menuSelectOption= Console.ReadLine();

Hope I understood your problem correctly. 😀
