modifying MSVC++6.0 included header files
stdlib.h has the function itoa(), which converts an integer into a character array - I was wondering, how would I go about finding the source code for this function so I could modify it? I would like to make it into a ftoa, float to array.
stdlib.h includes: Code:
_CRTIMP char * __cdecl _itoa(int, char *, int); but I can't find the source code for it - does MS hide it?

There's no need to write an ftoa function. sprintf() is your friend here.
Code:
sprintf(buf, "%f", float_val);

Also, to answer your question about the source code for itoa(), the source for the lib functions comes with the enterprise edition IIRC (and I don't think it's installed by default either). With all other editions, you just get the compiled object code, included in the lib files. We had a discussion about how libs are built, a while ago.

so um, at the risk of sounding stupid, how do I use that command? I want to convert the float value in tmpRec[iA].getCost() into a character array. I know that I would put my function call in the 3rd parameter, but what goes in the other 2?

Something like this:
Code:
char buf[100]; sprintf(buf, "%f", tmpRec[iA].getCost());
