I am going to speak in cotext to c language.
NULL is a macro defined in header files such as
stdio.h,stdlib.h,alloc.h,stddef.h,mem.h.The c pre processor
substitutes NULL by the value 0.Its declaration appears to
be like #define NULL 0 in the standard libraries.It is
used to initialise pointers to 0 and helps in portability.
It is a null pointer constant a convention for programmers
to initialise pointers.It is used mainly with pointer.
0 is simply an integer constant.
/0 is a backslash character contant used to indicate end of
string or a string terminator.
