I think they're probably just typos

That was the point I was making.

Four, actually, and one of them was more than a type. You use <iostream> but referenced cout and endl without a namespace.

And don't be so mean and vague, Ekted. What he's saying, Donkano, is that the real way to do it is actually via printf(), a reasonably simple function that is practically built in to the OS (or at least a heck of a lot closer than the iostream classes are).

I wasn't willing to actually compile it. I just eyeballed it.

Of course it does, but that's not very platform-independent. (And Windows is hard to deal with anyway.)

You can't cout objects either without each object having its own serialization code, which is the same as adding custom code with printf.

@Ekted: How would you add custom code to printf() without recompiling the CRT? Wouldn't you have to rewrite printf() in your own app?

I don't mean IN the printf code, I mean just have a function that takes an "object", and printf's the desired info. It's exactly the same with C++, just hidden.

There's more than meets the eye!

Code: Show/Hide
#include <iostream>
#include <stdlib.h

int main(int argc. char *argv[])
(
   cout << "Hello, I am your computer talking." << endl;
   system("PAUSE");
   returm 0;
)


1. #include <stdlib.h (not to mention deprecation)
2. argc.
3. ( instead of {
4. cout instead of std::cout
5. endl instead of std::endl
6. returm
7. ) instead of }

3 and 7, and 4 and 5 are the same errors really, but still, that makes at least five.

8. In "Hello, I am your computer talking.", the computer's not really talking. :-)

it looks nice to be able to do on one line

cout << "obj1: " << obj1 << ", obj2: " << obj2 << endl;

instead of having to memorize the functions for the diifferent objects and using multiple lines (although I suppose you could give your objects a print() function):

printf("obj1: ");
printObject(obj1);
printf(", obj2: ");
printDifferentObject(obj2);
printf("\n");

but these are small apples in either case.

what do I need to #include for write() in Windows?

There's a low-level function in the RTL called _write(). The include file is io.h. But I wouldn't normally use this. I like fwrite/fputs. The actual Windows function is called WriteFile(), but you really shouldn't use the OS-specific calls for run-time things unless you REALLY need to optimize.

And the run-time library stuff is a lot easier to use than Windows.

What I was trying to say before is that without extra work you can't really do
Code: Show/Hide
printf("Hi, %s, your stats are %o.", name, stats);
. Yes, the C++ version is just a bunch of different function calls and it is nicer just to have one, but in this specific case I do think the C++ way wins out.
