Just a simple Question

[Zenogear11]

Are there any programs that do not use <iostream.h>??
Im just wondering, because I am.

[abc123]

of course.

Like what? Is there a 2 line example program I could see?

[abc123]

id suggest that most windows based programs ( winapi ) wouldn't require it.

here's one for you:

int main(int argc, char *argv[])
{
  return 0;
}

iostream.h is a c++ thing. no c programs (ex: linux kernel, gcc, sshd, apache, emacs, ...) use iostream. nor do most windows apps (that don't use a text interface).

you can write a console program that doesn't need to output or input anything, so iostream would not be needed.

a console program that doesn't do any io is not much of a console program, i would say.

#include <stdio.h>

int main(int argc, char *argv[])
{
  printf("hello world\n");
  return 0;
}

well, you could just write a program that takes input from a file, and output to another file, no need for cin and cout, just ifstream and ofstream stuff.

that's not a console program, in that it makes no use of the console. a console program would fail (or be totally useless) if you closed stdin, stdout, and stderr before exec'ing it, whereas a program that only does file io would not.

Well, Im glad my question has posed some controversy between programmers
Thanks for anwsering!

its not like "iostream.h" is the only way to get input / output from your console app.

Well, you could always use the c libraries (printf, etc.) for your i/o for a console app.

errr!

Disregard that last post -- wrong post.
