Re: [Dev-C++] Casting of int to string

[Jonathan W. <jon...@gm...>]

Just a note:
""" It basically prints your integer into the character array, as long as
there is enough space to hold it """
Actually it will print the integer whether there is enough space or not.. It
is entirely Your job to make sure there is enough
space, or else sprintf will just keep on printing in memory after the
end of the array. Obviously this is a very bad idea, since there is
other data there.
In this case, determining the necessary space is as easy as 'what's the
maximum digit count in an integer'... but in other cases, you can get wierd
crashes, wrong
data for no apparent reason, or even create an exploit in your program.

Thought you might want to know that (and if you did, no offense intended :)
