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.
I hope this helps u

The pragma directive is used to access compiler-specific preprocessor extensions.

Is there any pragma directive in other languages???

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).
