Program Requirements Jack is a teacher in a high school. He wants you to help him calculate a class average, highest mark and lowest mark. Jack needs a program to be applied on a known and an unknown number of marks. In addition, the program can do the calculation as much as Jack wants. The program should do the following: 1. Ask Jack to enter if the number of marks is known or not. If the number of the marks is known, ask Jack to enter it. Otherwise, continue until Jack enters -1 to stop the input. 2. Whether the number of marks is known or unknown, find the class average, highest mark and lowest mark for the entered marks. 3. Ask Jack if he wants to enter another group of marks. If yes, go to step 1. Otherwise, end the program. 4. Validate the entered mark. The valid value is between 0 and 100. If Jack accidentally entered a mark out of this range, ask him again. Ensure you allow Jack to answer Yes/No questions using capital or small letters. Assessment Program with syntax errors will not be graded. This assignment is out of 100.
