I had write a program to:
A. Asks a user for a quiz average, a practical average, and an exam score.
B. Calculates the overall average based on the CS330 grading formula.
C. Based on the grading scheme in the CS330 syllabus, assigns a final letter grade.
D. Displays as outputs the overall average and the assigned letter grade along with an appropriate output explanation message for each output.

The input will calculate base on the following grading scale:

Quizzes: 10%
    Practical Assignments: 50%
    Exams(2): 40%
Grades will be assigned according to the following scale:
    A: 91-100%
    B: 81-90%
    C: 71-80%
    D: 61-70%
    F: < 61%

I did write the program, but for some reason, my program can't calculate for the Overall average.
Please, check on my attach program, help me to find out what is wrong, and help me to correct it so it will work.
Thank you very much for your help.
