What's this symbols ? - Ricop522 - 25.05.2011

":" "?"
pawn Код:
new a;
a = 1;
if(a == 1) : print("a == 1!") ? print("a == 0!");
Is this correct?

Whats ?, :, and
What's return 0x1 ? is return 1; ??

Re: What's this symbols ? - blewert - 25.05.2011

? and : are triadic or ternary operators.
Clickety!

They're handy because you can use them in assignment (or pretty much any statement for that matter), for example:

PHP код:
new bool:a = false;
new b = ( a == false ) ? ( 3 ) : ( 2 ); 
b would be assigned 3, because a is evaluated as false, and it returns 3.

this could also be wrote out as:

PHP код:
new bool:a = false;
new b;
if( a == false )
{
      b = 3;
}
else
{
      b = 2;
} 
The code you posted:
PHP код:
new a;
a = 1;
if(a == 1) : print("a == 1!") ? print("a == 0!"); 
Isn't correct, the correct way of writing it would be:

PHP код:
new a;
a = 1;
print( ( a == 1 ) ? ( "a == 1!" ) : ( "a == 0!") ); 
As for 0x1 in the return, yea it's a hexadecimal representation of the value 1. See more about hex & pawn here:
