This function is deprecated, I already tried that and it worked but the correct way to do it is to use a std::string.
avansc your getting to old!

lolz, thats just a compiler warning, nothing serious. i doubt that you will trite code that will crash if you use it.
again, you compiled with a C++ compiler, try using something good like gcc.
i might be getting long in the tooth.. ;(

Yeah, that's what I was thinking when I saw this topic. That's why I didn't respond until
after the solution had already been presented, because I don't know how the hell to do some of the good ol' fashioned C things with C++ whore strings.

Yeah, Microsoft has new versions for all of the oldschool C functions that handle exceptions and stuff like that. I still recommend the standard C stuff...

In college, we weren't allowed to use strings - even if we wrote our own string class... It was char arrays all the way - but, it was good experience.

Well I'm a perfectionist, I spent 2 months rewriting my code so I could remove a 64Kb memory leak.

In this case, I'd use itoa(). Although iirc it's not standard [but atoi is]. C++ doesn't really have better conversions...
Making your own itoa is this:
Code: Select all
char[] itoa(int i) {
char buffer[256]; // w/e
sprintf("%i", buffer);
return buffer;
}

Yeah, I have had classes where we weren't allowed to use strings either. Honestly though, I think the character array manipulation was good for me. Too many C++ programmers don't know how to handle C style character arrays...

I know how to do that and then some for instance I used to manage my own arrays and didn't even know about std::vector. You have no idea how complex that made stuff, I learned a lot from it though and I agree that itoa() is much more logical but I've been trying to do absolutely everything by the book. it's worked out well though most of the stuff I just find retarded, I'm hoping to use this as an example of my work in the future.

i would suggest not to use std::vector, especially if you are so adamant on staying efficient.
or anything C++ gives you that makes something people think is complicated into something thats easy.
if you dont know the machanics of something C++ is lettign you use you will have a shit hoard time trying to make something effiecient, becauyse you wont know where your code is being inefficient.

The standard template library in C++ is actually pretty damn huge when it comes to executable file size. I'm not saying whether I recommend you go one way or another, but you mentioned efficiency, so I thought that I would bring this up.
