Translating Global Variables as Structs?

[deltatux]

Hey guys,

Apparently I made a poor design choice by declaring a global variable for my whole program and need to now "privatize" it. Would a good idea just be to translate them into structs by putting them into them and then just tell my code to just call them up whenever needed instead of going through the whole software and pass variables all over the place?

It's generally bad if you need to access something globally. So unless this is one of those rare exceptions (and it's almost certainly not) you should rewrite your code so that you don't need global variables. Or have to pass a struct to everything.

Are the variables that are currently global related? If so, you may want to use a struct. Otherwise, just pass them to functions separately.

Well, the whole software only really rely on 7 variables (unless they are just temporary variables) so to reduce the number of lines of code, I thought it was a good idea to declare them as global variables. However, I forgot about the fact that it may lead to code security issues. Thus, I got marks docked off.

However, I'm not too sure how to rewrite the program to not use global variables without a complete rewrite by having variables being passed since it's going to use up a huge amount of time to do and which I don't have since final exam is around the corner.

How would I go about using structs to solve this problem if I was to use structs?

Thanks,

Alright, I quickly redid the whole program doing the old slow traditional passing method... thanks anyways guys.

The old slow method isn't really slow, and it's a much better way of writing code

Actually, in most languages, its faster I'm not sure about C, but most languages, its faster to access local variables than global. The way it usually is, is local->outer scope->global.

I agree it's much better to write it, but it's so much more typing =P.

Anyways, what's done is done now !
