    i was told by my supervisor that i was meant to write f1 as a function of i when it was in the loop!
    I see. What does f1() do, and why on earth do you name it f1 when you can use a more descriptive name?

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. 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.

    ok, ill change it! it is a function that is defined outside of int main. it has to compute values of a function at each iteration step in a loop statement. hence it is dependent on i! i have defined it at the top outside main, and then put the formula at the bottom after my return(0) }. the problem is that im not sure how to make it use the formula for each iteration step, also i have arrays in there, so it complicates it even further and puts it outside of my knowledge!
