Question

I dont know where to start PLEASE HELP ????

Create a program that interacts with the user. The code must have 1-7 features:


1. Use at least 4 objects (instances of different classes)
2. Use at least one example of inheritance
3. Use at least 2 loops
4. Use at least 2 selection statements
5. Use a random number
6. Include at least one array
7. Include data validation with proper prompting for valid input when data entered is wrong.

I was thinking about starting by creating a basic design using UML and high level logic design but I don't know where to start if possible can you be visual (flowcharting) or text (pseudocode).

I thought of a program like a Math Tutor program that would do the following:


1. Prompts for the current user’s name
2. Gives instructions
3. Provides a menu of math choices (e.g., +. -, *, /), plus exit
4. Asks users how many questions they want to answer
5. Asks user for highest number to use
6. Displays appropriate math questions with random numbers
7. Keeps track of right and wrong answers
8. Provide any of a number of randomly chosen correct and incorrect answers for feedback
9. Gives feedback on how many questions answered and percent right for that group
10. Returns to menu for possible additional problems
11. When exit chosen shows grand total statistics – correct, attempted, and percent right


• Can you tell me how you met the 7 requirements

Please Help ??????
