The document describes a C# program for converting numbers into their word representation. It includes functions to process ones, teens, and tens, and handles numbers up to three digits. The program prompts the user for input and then displays the corresponding numeric words.

2. Counting Pattern
• 0,1,2,3,4,5,6,7,8,9
• 10,11,12,13,14,15,16,17,18,19
• 10, 20,30,40,50,60,70,80,90
• 100….999
Unit/Single Place
Tens Place ( spoken as ---teen)
Tens Place (spoken as ---ty)
Hundreds Place (Min-Max 3 digit
numbers)
