I have a palindrome program.Is there a way to ensure user input terminated in a string by a punctuation mark (e.g. ‘!’, ‘.’, or ‘?’.) in an array? And how do i get the program to exclude commas?

You didn't post any code so I am assuming you are just interested in general help.
Check out string.h (they have a nice writeup on Wikipedia) which will give you some ideas about the kinds of string handling functions available in C.
Good luck!

Get the length or the string, check the last character with the function ispunct()
And how do i get the program to exclude commas?
Copy the input line to a temp line. Use isalpha() to check if the character is a letter and copy only letters. If you want letters and numbers, use alnum() . This will exclude all non-palindrome characters.
Last thing, make sure when you do the copy you convert all the letters to upper or lower case (use toupper() or tolower() ). This is because 'A' != 'a'
