Why Pragma's are used in C++??

Answer 1

The preprocessor directive #pragma is used to provide the additional information to the compiler in C/C++ language. This is used by the compiler to provide some special features.

1.) #pragma startup

Before the execution of main(), the function specified in pragma is needed to run.

2.) #pragma exit

Before the end of program, the function specified in pragma is needed to run.

3.) #pragma warn

Used to hide the warning messages.

Is there any pragma directive in other languages???

Answer 5

Just for instance, some of compiler features are not easily accessible from the interface (kind of), so using pragma directives can reach it with its extensions.

Example : E/D warnings extras sollicited by (#pragma warn).
