today while I was coding I ran into a problem I couldn't figure out.

So my task is to print a chosen amount of characters, the catch is I need to also specify how much characters are in one line.

For example:

I need to print 24 characters '*'

1. I select the character.
2. Select how many: 24.
3. Select how many character per each line: 7.

Result should look something like this:

*******
*******
*******
***

I have to strictly use nested loops!

Code example:

    static void Main(string[] args)
    {
        char character;
        int charAmount;
        int charAmountInLine;
        Console.WriteLine("Select character");
        character = char.Parse(Console.ReadLine());

        Console.WriteLine("Select total amount of characters");
        charAmount = int.Parse(Console.ReadLine());

        Console.WriteLine("Select amount of characters in each line");
        charAmountInLine = int.Parse(Console.ReadLine());
        Console.WriteLine("");

        for (int i = 0; i < charAmount; i  )
        {
            for(int j = 0; j < charAmountInLine; j  )
            {
                
            }
        }

    }
}

}

In this program, you need to identify:

1. Number of lines that print full characters in a line (row)
2. Print the remaining characters (remainder)

Concept:

1. Iterate each row (first loop).
2. Print character(s) in a line (nested loop in first loop).
3. Once print character(s) in a line is completed, print the new row and repeat Step 1 to Step 3 to print full characters in a line if any.
4. Print the remaining character in a line (second loop).

int row = amount / characterPerLine;
int remainder = amount % characterPerLine;

for (int i = 0; i < row; i  )
{
    for (int j = 0; j < characterPerLine; j  )
    {
        Console.Write(character);
    }
            
    Console.WriteLine();
}
        
// Print remaining character
for (int i = 0; i < remainder; i  )
{
    Console.Write(character);
}

First of all count number of rows for outer loop

int numberOfRows = (int)Math.Ceiling((double)charAmount / charAmountInLine);
for (int i = 0; i < numberOfRows; i  )
{
    charAmount -= charAmountInLine;
    charAmountInLine = charAmount> charAmountInLine? charAmountInLine: charAmount;
    for (int j = 0; j < charAmountInLine; j  )
    {
        Console.Write(character);
    }
    Console.WriteLine("");
}

Try this one:

int row = (int)Math.Ceiling((double)charAmount/(double)charAmountInLine);
int column = 0;
int temp = 0;
for (int i = 1; i <= row; i  )
{
    temp = (i * charAmountInLine);
    column = temp < charAmount ? charAmountInLine : temp - charAmount;

    for(int j = 0; j < column; j  )
    {
        Console.Write(character);         
    }
    Console.WriteLine();
}

temp means temporary variable, just have no idea how to call it ;)
