Question

I’m a student and I got a homework i need some minor help with =)

Here is my task:

Write an application that prompts the user to enter the size of a square and display a square of asterisks with the sides equal with entered integer. Your application works for side’s size from 2 to 16. If the user enters a number less than 2 or greater then 16, your application should display a square of size 2 or 16, respectively, and an error message.

This is how far I’ve come:

        start:
        int x;
        string input;
        Console.Write("Enter a number between 2-16: ");
        input = Console.ReadLine();
        x = Int32.Parse(input);
        Console.WriteLine("\n");
        if (x <= 16 & x >= 2)
        {
          control statement
          code
          code
          code
        }
        else
        {
            Console.WriteLine("You must enter a number between 2 and 16");
            goto start;
        }

I need help with…

… what control statment(if, for, while, do-while, case, boolean) to use inside the “if” control.

My ideas are like…

do I write a code that writes out the boxes for every type of number entered? That’s a lot of code…

..there must be a code containing some “variable++” that could do the task for me, but then what control statement suits the task best?

But if I use a “variable++” how am I supposed to write the spaces in the output, because after all, it has to be a SQUARE?!?! =)

I’d love some suggestions on what type of statements to use, or maybe just a hint, of course not the whole solution as I am a student!

Answer 1

the control statement is:

for (int i = 0; i < x; i++)
{
  for ( int j = 0; j < x; j++ )
  {
    Console.Write("*");
  }
  Console.WriteLine();
}

This should print a X by X square of asterisks!
I’ma teacher and I left the same task to my students a while ago, I hope you’re not one of them! 🙂
