if i use this method to check to see if the file exists, when the file does exist what do i use to load the file contents into an array?Code:int fileIn( char *f ) {
FILE *fd;
if( ( fd = fopen( f, "r" ) ) ) {
/* file exists */
fclose( fd );
return 1;
} else {
/* file doesn't exist */
return 0;
}
}
fread()
Google is your friend.
It depends on what the file contains.
Also, that's a rather C way of doing things, shouldn't you be using C++ io streams?
its going to be loading numbers and could i get an example of how to use it, i looked it up on that website from another post and ive searched this site but i dont understand how to use it.
alright i appreciate all the help, but i plain hate smart remarks. what is the purpose of a forum if all you get is links to here and there instead of actual help. sometimes it makes alot more sense when someone explains it to you rather than just looking on some guide that seems like something a computer generated.
But the question has been asked and answered a million times. The function is well documented, there's no reason for anyone to have to explain it to you...
if you dont want to give me an example, fine you dont have to. ill just ask some where else.
hmm, if I were you I'd look into std::ifstream for input and std::ofstream for output. They're much easier to work with (in my opinion, of course :D I've never tried FILE's)
We already did this in your first thread.
Your problems are stemming from the fact that every variable you use is global.
I told you how to implement a solution using C++'s ifstream objects.
Don't let the door hit you on the way out.Quote:

hmm...imperito if you had even bother to check back on my last post you would have realize that i said that method didnt work either
ive had no problems with those global variables till you started offering suggestions that just caused more problems.
your all lazy, you cant type out one example, you have to just point to someone elses work that sometimes to hard to understand by someone that doesnt know what he is doing.
i spent all day searching stuff on ways to accomplish what i wanted to accomplish i searched all over these boards and websites that i found on other posts which all led me to some site with stuff that made no sense.
try offering some help instead of just pointing here or there to something else.
I already posted a snippet of code in the other thread. I think your reason for not being able to adapt it was, oh let me think...
Most of the people who stop by here aren't going to write your program for you. If you would post the problem code, and the errors you receive, then we could help you.Quote:
for some reason
Except that the code you posted before DID have a problem, one which directly pertained to your misuse of global variables.Quote:
ive had no problems with those global variables
If you want help with something, fine. But you need to be able to ask the question properly, not just say "X doesn't work someone do it for me"
i didnt have any problems with my file untill i started getting help from you, all i wanted to do is to make it check to see if the file exists or not and you all throw these long responses back at me like im supposed to understand the whole thing, and it still didnt work it just gave me more errors.
Last resort plan, if you can't figure out what we're talking about:
Buy a good book like "Sam's Teach Yourself C++ in 21 Days" and take a look at the file i/o section. Guaranteed, the book will teach you lots of useful stuff (not only file i/o), if you're smart enough to be doing C++ in the first place.
