Implement one array of the English alphabet (26 characters). a) Create a function, getLetters() to cast and generate the array. b) Create a function, printLetters() to output the array. c) Create a function, swap() for swapping character variables. d) Create a function, reverseLetters() uses a loop and the swap() to reverse all array elements. e) Call printLetters()to Output the updated array. Hint: Set a variable for the first and last indices. Swap those values. Gradually move the first/last pointers to the middle of the array, swapping as you go. When the middle is reached, the array will be reversed.
