Write a program palind.c that reads a message, then checks whether it's palindrome (the letters in the message are the same from left to right as from right to left): Enter a message He lived as a devil, eh? Palindrome Enter a message Madam, I am Adam Not a palindrome Ignore all characters that aren't letters. Use integer variables to keep track of positions in the array. Revise the program in Part I to use a pointer instead of an integer to keep track of positions in the array. Name the new C program as palindP.c
