We have functions for many reasons. If some chunk of code performs a well-defined task, placing it in a function can lead to clearer code. It allows us to reuse the code, if the same thing has to happen in more than one place. It allows us to provide a pointer to the function, which lets other code invoke our code even though it doesn't know anything about it. It also enables recursion, which would not be possible otherwise.Originally Posted by Hirumaru
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
That's kinda what I meant. You can't keep going back to main() for everything. Especially not so when your program has hundreds of lines of code and performs dozens of distinct operations.
You need to be able to find, use, and reuse code efficiently. Otherwise your program'll get bottlenecked asking the same code for twenty different operations all at once.
Heh. Programming is going to be so much fun. ^_^

You've grasped the point I think.
Now, wait until you look at a multi-million line programI used to work on a codebase of 1.4 million lines. Now I only have to deal with 65 thousand lines, which seems small in comparison.
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
Just as long as I don't get eaten by an over-sized chicken like Dennis Nedry. @_@Now, wait until you look at a multi-million line program
