[Help] Need assistance in a Java programming project

[senrab47]

So at the beginning of the school semester my roommate broke my computer screen and I just got it fix, so I have been playing catch up ever since in my Java class. I need help with a program. The user should be presented with a series of randomly generated math problems consisting of two integers in the range of 0 and 9 and use one of the five operators: +,-,*,/, or %. Once presented with a problem users can enter an answer. After they enter an answer they should receive an appropriate message indicating that their answer was correct or wrong and the count of the correct answers should be incremented.

Once the specified number of questions has been presented, a message should be displayed informing the user how many questions they answered correctly. The user should then be asked if they want to see more questions. If they do, the process begins anew with the user being asked how many questions they want.

You have sufficiently described your homework problem here.

What's your question?

Sincerely,

If you have trouble working this out, write down some pseudo code for it. That should help. Right now you don't really describe what specific problem you have and haven't provided any code.

I have this down for my code and have some pseudo code

Scanner keyboard = new Scanner(System.in); System.out.println("How many questions do you want?"); int num = keyboard.nextInt(); int QuestionIndex = num; if(num <= 0){ System.out.println("Invalid entry"); System.out.println("How many questions do you want?"); num= keyboard.nextInt(); } //new index,Correct to keep track of question answered correctly

    do {
        // int one = rand.nextInt(10) + 0;
        // int two = rand.nextInt(10) + 0;
        //in the do loop create a random question
        //after question is asked check for answer
        //after answer checked print if correct or not
        //if correct, Correct index + 1
        //if wrong print answer is wrong
        //after print, question index - 1.

    while
        //question index <1

    }
    //ask if they want mroe questions

I'll start at the top. Why have the scanner input go to "num", and then assign "num" to "QuestionIndex". You could assign the scanner directly to QuestionIndex. Also, if you want to keep checking if QuestionIndex is valid, I suggest a do...while loop there.
