Help with program

[lf95]

Can someone help me write a program to compute the computer programming grades of 8 IT students.

● Randomly create student numbers for each of the students and store each in an array.

The program should take the input of (validate the input where appropriate):

● Names of Students and store them in an array.

● Addresses of Students and store them in array.

● Previous Grade for student. (A,B,C…..)

● Marks for ‘Computer Programming Assignment 1’ (out of 25 marks)

● Marks for ‘Computer Programming Assignment 2’ (out of 25 marks)

● Marks for ‘Computer Programming Exam’ (out of 50 marks)

● Based on the above input, work out the ‘Final Marks’ for Computer Programming (Assignment

1 + Assignment 2 + Exam) and store it in an array.

Then work out and display

● The average Final Grade for the ‘Computer Programming’ class 2013.

● The number of A’s, B’s, C’s, D’s, and Fails for ‘Computer Programming’ 2013

● The name, address, previous grade, this year’s grade, percentage, and student number for

each student.

As you have not shown any work I cannot provide you with any specific examples, however you will want to take a look at the Random class and arrays

Please show the work you have done and ask a specific question to get more helpful results.

Please help!

That's a good start... Exactly what help do you need next (be specific)?

How do I store the grades?

[JamesCherrill]

If grade is always just a sinle letter you can use an array of chars, if not use an array of Strings
