81. Split a String Using Delimiter

You are given a null-terminated string containing words separated by a delimiter character (like comma , or space ' ').

Your task is to:

• Split the string into individual tokens based on the delimiter
• Store the tokens in a 2D array of characters (char tokens[10][20])
• Print each token on a new line

Do not use strtok() or any string library functions.

Example-1

Input:
str = "cmd1,cmd2,cmd3"
delimiter = ','
Output:
cmd1  
cmd2  
cmd3

Example-2

Input:
str = "ON OFF RESET"
delimiter = ' '
Output:
ON  
OFF  
RESET
