this is c program. please help me to solve this problem

(a). Write a program that reads a message, then prints the reversal of the message: Enter a message: Don't get mad, get even Reversal is: .neve teg ,dam teg t'noD array. Stop reading when the array is full, or the character read is 'In (b). Revise the program to use a pointer instead of an integer to keep track of the current position in the array. (c). Simplify (b) by taking advantage of the fact that an array name can be used as a pointer. You may write a single program and make three different functions for (a), (b) and (c). Let the user choose which of them to execute from the main function. Each C file should also have your name and date with the lab number in the header at the top of the file. The purpose of the program should be clearly mentioned in the header. Each C file should have adequate comments that describe the program statements. All code should be neat and properly indented/formatted
