• Read 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, and then terminate.
• Write a function that takes the user's input string as an argument and returns the sub-string consisting of the odd characters in the input string (see example below).
• Write a function that returns a variable indicating whether the "odd string" is a palindrome.
• Output the odd string to the screen, and also a message saying whether or not the odd string is a palindrome.
• The program must work successfully with input strings of any size, and you must use dynamic memory allocation.
• You must use valgrind to check your program for errors. If valgrind produces any errors, there will be a grade deduction even if the program seems to run ok. The amount of the deduction could be small or large depending on the nature of the error..
