Re: A89: ASM Mentoring
There is no reason that
cout << "Some text.";
should produce any more code than
printf("Some text.");
though I've never tested it. If anything, I believe printf() should produce
more, assuming the C++ compiler/linker is reasonably well implemented. Why?
Consider all the different things printf has to know how to deal with:
strings, chars, int, short, long, float, double, long double, pointers, not
to mention all the formatting options. Of course this assumes that printf()
handles all these things by itself, without making any function calls, which
would be a stupid way to implement it.
The C++ statement makes only one function call, to the
ostream::operator<<(char *) function, and that function only needs to be
able to deal with strings. There is no reason that any other ostream
functions (other than a constructor, which doesn't need to do much) would
need to be linked. Of course this all depends on the implementation.
The fact of the matter is that most of the claims about C++ being too big
and too slow are completely unfounded. Yes, it has certain features that can
slow it down and make the code larger, but it's not necessary to use them.
