What is #pragma once
What this directive will do
Anonymous
??
BinaryByter
you know
BinaryByter
if you include a file twice
BinaryByter
the compiler might have problems
BinaryByter
so with #pragma once
BinaryByter
the compiler will make sure not to include the file twice
Anonymous
Means I know about #pragma startup and #pragma exit
#pragma GCC poison also..
BinaryByter

#pragma GCC poison also..
you don't need to learn #pragma by heart
BinaryByter
they are NOT part of the C++ language
Anonymous
But why we will use #pragma GCC poison
Anonymous
??
BinaryByter
But why we will use #pragma GCC poison
its a way of making sure that your function won't be used
BinaryByter
like lets say that you have a function
Anonymous
Means if I write #pragma GCC poison printf
BinaryByter
that is a subfunction
Anonymous
It blocked printf
BinaryByter
but that CANNOT be used without the upper scope function

In my prog
BinaryByter

#ifndef.
Why we specify this
Anonymous
??
MᏫᎻᎯᎷᎷᎬᎠ
you should prefer them over #pragma
Yeah
But I think pragma is not supported by all compilers or standardised
BinaryByter
but it checks wether a symbol is defined
Anonymous
BinaryByter
(almost) everything that is #pragma is not in the standard
Anonymous
But most compilers accept it
Anonymous
Yeah
But I think pragma is not supported by all compilers or standardised
GCC also support now some pragma. But orefix with GCC
BinaryByter
That's
Why
For code portability purposes
Include guards are better
C++20 will have modules
BinaryByter
thats going to be some epic shit

What the meaning of this statement👇👇
#ifndef TEXT_DIALOG
#define TEXT_DIALOG
BinaryByter
What the meaning of this statement👇👇
#ifndef TEXT_DIALOG
#define TEXT_DIALOG
first it checks if TEXT_DIALOG is NOT defined
BinaryByter
if it is not defined, it will define TEXT_DIALOG
BinaryByter

That is the ambiguity bro..
Uf developer already know that TEXT_DUALIG has to define..then why he didn't do it before..
??
BinaryByter
BinaryByter
#ifndef TEXT_DIALOG
#define TEXT_DIALOG
BinaryByter
this is the same as #pragma once
BinaryByter
the first time that the file is included, TEXT_DIALOG isn't defined
BinaryByter
but the second time, it is already defined
BinaryByter
so the compiler won't include the code

Oh..okey
