C program

Pass in a string as a command-line argument (scanf, fgets, gets, etc. may not be used).

If no command-line argument is given, output a message telling the user the expected usage.

Write a function that returns the sub-string consisting of the odd characters in the input string.

Write a function that returns a variable indicating whether the "odd string" is a palindrome.

Output the odd string and a message saying whether or not the odd string is a palindrome.

The program must work successfully with input strings of any size
