I’m trying to create an application that inputs a Width and Height to design a square. I’ve gotten the error handling for inputting the numbers for the Width and Height. I find myself writing…
//Integer for Width == W
int W;
//Integer for Height == H
int H;
if (W == 1 && H == 1)
{
Console.WriteLine("*");
}
else if (W == 1 && H == 2)
{
Console.WriteLine("*n" +
"*");
}
else if (W == 1 && H == 3)
{
Console.WriteLine("*n" +
"*n" +
"*");
}
//~~~~~~~~~~~~~~~~~~~~~~~~~~~
else if (W == 1 && H == 20)
{
Console.WriteLine("*n" +
"*n" +
//~~~~~~~
//For readability 20th"*");
Also, assuming I’d do (else if) another 396 more times to satisfy the variances (20 * 20 = 400) 400 possibilities to build this square.
I’m asking if there is any looping methods that could help me reduce the code I need to complete making my square out of Console.WriteLine(“*”).
if(W == 1 && H == 1) ~~~ else(W == 20 && H == 20)
Or am I stuck writing the 400 possible instances of the width and height of my square?
The desired result for the display

Thanks for your time and consideration of my question.

Logic would be simple:
write * character as many times as W, then write new line to start new row – repeat this as many times as H
Putting it into code:
var W = 10;
var H = 10;
for (var i = 0; i < H; i++)
{
for (var j = 0; j < W; j++)
{
Console.Write('*');
}
Console.WriteLine();
}
Using more concise code:
for (var i = 0; i < H; i++)
{
Console.WriteLine(new string('*', W));
}
UPDATE
In order to draw only border with characters:
var W = 10;
var H = 10;
for (var i = 0; i < H; i++)
{
// for bottom and for top borders - print full line
if (i == 0 || i == H - 1)
Console.WriteLine(new string('*', W));
// for other, print just W-2 spaces with * at the edges
else
Console.WriteLine('*' + new string(' ', W - 2) + '*');
}

You can achieve it via nested loops and a bit of formatting while outputting * to console.
var width = 50;
var height = 50;
for (var x = 0; x < height; x++)
{
for (var y = 0; y < width; y++)
{
if (x == 0 || y == 0 || x == (height - 1) || y == (width - 1))
{
Console.Write('*');
}
if (x > 0 && x < (height - 1) && y > 0 && y < (width - 1))
{
Console.Write(' ');
}
}
Console.WriteLine();
}
