Compiler issues?

I ment more along the lines of how will the two outputs differ...  because the latter code works and it all sends properly, but sprintf() doesn't.

Less overhead, you're only making 1 function call instead of 2. Any time you can cut down on the number of different functions that need to be loaded into memory, you're improving the efficiency of your program.

Not true.  If you have a large section of code that is used lots, it's better to put it in it's own function.

Yes, obviously it's always better to load one 10 kb function than two 100 byte ones.

Well, within reason, of course.  Assuming, though, that you have some well-defined goal, and that there are two ways to do it: one with one function, and one with two. Generally I wouldn't expect the actual amount of code necessary to accomplish the goal to be much different, so using a single function has the advantage.

Well, what we were talking about here was whether to use strcpy and strcat or to use sprintf... At least that was the question you replied to. Nothing about writing your own functions in that post as far as I can see. And choosing between those, I think using strcpy and strcat is the more efficient choice for a small program.

well considering that's the only one that works, I'll go with that one... thanks
