    Returning Arrays?

    Is it possible to return an array, or more then one variable from a function?

    Thanks,
    Nathan

    No. However, you can return a pointer to an array (but note that the array cannot be local to the function) or you can return a struct that consists of multiple values.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    95% of the cases when "you want to return an array", what should REALLY happen is that you pass an array INTO the function, and use the passed in array to fill in the data.
