The following programming exercises are to be developed using all phases of the development method. Be sure to make use of good programming practices and style suck and constants, whitespace, indentation, naming conventions, and commenting. Make sure all input prompts clear and descriptive and that your output is well formatted and looks professional. 1. Write a program that includes the following three functions: a. isPalindrome - This function returns true if the cStringparameter is a palindrome, false if not. As you have seen, a palindrome is any group of characters (i.e., a word) which appears the same written both forward and backward. b. isAlphaStr - A function that returns true if the cString you pass it contains all alphabetic characters. If the parameter does not contain all alpha characters, return false. Feel free to use the isalpha function we discussed earlier. c. countChar - A function to simply count and return the number of times a specific character occurs in a cString. This function will take two parameters, the cString to check and the specific character you are looking for. Within your program make sure you clearly exercise all three of the above functions
