Pointer for those who will take the completion exam

You will be required to write a complete program.

Try developing simple programs on your own.

Possible problems.
1. Write a program that will generate a typical calendar for a year that is entered at run time.

2. Write a program for a simple text based calculator. The program should aid the user in adding, subtracting, dividing and multiplying two numbers.

3. Write a program that will aid the user to compute grades. At run time, the computer will prompt for the perfect class standing, the perfect exam score, the user's class standing and the user's exam score. The program will compute the grade corresponding to the user's class standing and the grade corresponding to the user's exam score by using an appropriate formula ( ex. grade = score/perfect_score * 50 +50). The user's grade is the average of the grade corresponding to the class standing and the grade corresponding to the exam score.
The process of accepting scores and computing the corresponding grade should be repeated as long as the user does not want to end.
