loop
[code]
I want it to randomly chose a question in the code. But since the v=rnd(4) is in the do loop it Shows all questions at once.

When ever i move the rnd(4) somewhere else it wont work

How can i get it to only show one question at random?

Please Help

-Thanks

Firstly, you have to put /code in the closing tag for the code box to work.

I assume you have just started programming, because you write the same way everyone does when they start; like your program is one long roll of parchment reading from top to bottom.
One of the first things you have to learn is to break down a complex idea into smaller tasks. When we learn maths, we learn the process, instead of trying to memorize every answer. Likewise to write an efficient program we must define procedures that can be repeated instead of rewriting similar code. Imagine if you wanted 1000 questions in your game, your program would be thousands of lines long!

Don't worry if you don't quite follow this I am writing it in a hurry, I or someone else will explain if you have any questions.

We make a quick plan, starting with the data we need:
* Questions
* Answers (four per question)
* A marker to tell the program which answer is correct

Since we want multiple questions and answers we will use an array.
An array is a group of variables, a bit like files in a filing cabinet where we can place a number in each file:
dim question$(14)
This array stores 15 strings (notice the $ in the name), it says 14 but always remember that you can store a value in 0 too!
So this is like a filing cabinet with 15 folders to store strings in, this is a one-dimensional array.

The answers require a two-dimensional array, because there is more than one answer per question.
dim answers$(14,3)
So in our filing cabinet there are 14 folders each with 3 files inside to store strings on.
I actually prefer to think of 2D arrays as a grid, the two numbers are like co-ordinates and we store our strings in grid squares.

The correct answer marker will also need an array
dim correct(14)
Notice this one doesn't have a $, that's because it stores integers, specifically the number of the correct answer (0-3).

We fill our arrays using the DATA command, it is very handy for filling arrays because it can be read sequentially like an external file.

An easy way to do your code is just to paste it into the post, then highlight it and click the code button.

Just a suggestion:
Use more obvious variable names. Variable names like c,v,i,o are all very ambiguous and it is impossible to know what is in each variable unless you trace through the code to find the line assigns it a value. By giving a variable a more descriptive name such as "QuestionNumber" or even just "Question" when you and others read your code, they know exactly whats going on, when its going on.
