Silly little fact

**fuh** · 12-31-2002

Did you know that the "hello world" program can be written in countless ways? Here are a few:

Code:

#include <iostream.h>
int main()
{
cout<<"Hello, world!";
return 0;
}

Code:

#include <iostream.h>int main(){cout<<"Hello, world!";return 0;}

Code:

#include 
<iostream.h>
int
main()
{
cout<<
"Hello, world!";
return
0;
}

Oh Yeah, acctually they are all the same, since the compiler locataes the semicolons to indicate the end of a statement, so new lines won't matter in a code like this...

**fuh** · 12-31-2002

We just use it like the first one for readible code.

That's true about anything in C++. In general, lines and spaces don't mean much -- it's semicolons and braces that really matter.

i think this is more a GD topic less u be having trouble with the code....

Wow, you weren't kidding when you said this fact was silly and little.

**TechWins** · 12-31-2002

I think there was a typo and Fuh meant to put "pointless little fact".

Yes, but it can even be written in more ways than that...

Code:

#include <iostream>

using namespace std;

int main()
 {
   cout << "Hello World";   
   return 0;
 }

Code:

#include <iostream>

int main()
 {
   std::cout << "Hello World";
   return 0;
 }

And actually my ways are the proper C++ ways hehe.

Then again it's not like that my ways are anything new to anyone so yeah I'm still not special.

Amazing, fuh, incredibly amazing. We're all newbies like you when it comes to programming, aren't we?

Code:

extern "C"
{
	system(const char*);
}

void main()
{
	system("echo Hello World!");
}

Code:

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
  int i = 0;
  char string[] = "Hello, world!";
  while(i < strlen(string) + 1)
  {
   printf(" ");
   i++;
  }
  for(i = strlen(string)-1; i > -1; i--)
  {
   printf("\b\b");
   printf("%c",string[i]);
  }	
  return 0;
}

Heh, heh, that was funny. I especially like this one.

I was actually a little worried if that was real until I got to the bottom of the page.

Erm, how does "Fuh" get pronounced (Foo - Ha)?
