a) Write a complete C program that takes two arguments on the command line when it is run: a string and a number. The second argument is represented by the last two digits of your student ID. The program replaces each of the string characters in an: even position with the *character, if the second program argument is an even number (for this purpose, zero is assumed to be an even number) or, odd position with the 'S' character, if the second program argument is an odd number. The program then displays the altered string. Notes: 1. You can assume that the input string is always less than 15 characters long. 2. You can also assume that the program's user always provides 2 arguments when running the code, which makes use of the main function's arguments. 3. You must use appropriate string related functions to achieve the program's functionality. 4. The program's variables must be sensibly named. 112 marks1
