Please help. I'm stuck on this debugging question in my C# course.

Debugging Exercise 5-3 The provided file has syntax and/or logical errors. Determine the problem and fix the program.

// Program displays every possible ID number for a company

// ID number is a letter, followed by a two-digit number

// For example -- A00 or Z99

// Go to a new display line after every 20 IDs

using static System.Console;

class DebugFive3

{

static void Main()

{

char letter;

int number;

const int LOW == 0;

const int HIGH == 99;

const int NUMINROW = 20;

for(letter = 'A'; letter < 'Z'; ++letter)

for(number = LOW; number > HIGH; ++number)

{

if(number % NUMINROW0)

WriteLine();

Write("{0}{{1} ", letter, number.ToString("D2"));

}

}

}

Thanks for any help.
