C++ help

[Nicky Peter Hollyoake]

How does define work then? Is abit like const? But it an do functions .... I kinda got it from this example.

#include <iostream.h>
#define print cout << ""

main() {
print"define test";
}

Thats one I made.

Are you writing a C program or a C++ program?

If you're writing a C++ program, start using <iostream> & stop using <iostream.h>, as it's deprecated.

You can use the #define statement in C++ but it's not really recommended that you use it a lot.

#include <iostream>

#define print std::cout << "" 

int main()
{
	print"define test" << std::endl;
	
	// Wait for a keypress
	std::cin.get();
}

I wouldn't mind learning both . But yeah i'm actually trying to learn C++. I found a site noe that I can learn from, and its just aiemd at C++.

Matthew, I got that from a C++ tutorial, and it still is "<iostream.h>" is the tutorial wrong? Go to the link djlinux gave, and get the first tutorial, its got it there (to be honest though, I only had a quick scan through, so it might just be showing thats it s mistake, i'll give it a quick check before I send this message). Nope that what it definy says.

The tutorial is out of date (a lot are) <iosteam.h> is deprecated, what compiler are you using? Most give you a warning about that.

[Nicky Peter Hollyoake]

Oooh! is that why I keep getting

warning This file includes at least one deprecated or antiquated header.

?

Whats the worse that could happen adding the extra ".h"?

[Supermonkey]

I don't know specifics, I just know you shouldn't do it .
