    Default Loops: Taking the average of a list of numbers

    The problem states that I have to ask the user how many quizzes they have taken. We take the number of quizzes they enter and prompt the user that many times (ex: they say 3 quizzes, we have to have an input dialog box 3 times asking them for their grade, separately) and each dialog box is unique, meaning it says: Enter quiz grade 1: , Enter quiz grade 2: , Enter quiz grade 3.

    then i have to take all of their quiz grades and find the average.

    I have to use a loop, and maybe an if statement, if necessary.

    please help, I am stuck and can't think of anything. thanks

    Use an array to store the data and use a loop to transverse through the array.
    Everything afterwards is pretty trivial.

    Please show your current code attempt. Please tell us any problems you may be having with your code attempt. You will also want to have a look at the Java tutorials section on for loops. Also before writing code, write out pseudo code to think through the logic of the program, the steps that the program will have to take to solve the problem. Only then should you try to write code.

    Well, first, think how you would solve this problem in real life. Your friend gives you 3 numbers, you calculate the average of them how you were taught in Math class. Then try to write the code for it.
