Answer / shani chaudhari
null(\0) is used for termination of string meance each and
every string ended with \0 while 0 is mostly related with
binary operations..null(\0) meance nothing but 0 has its own
value and existance. both are different

Answer / guest
NULL('\0')- A string in C is always terminated by a null
character.The ascii value of '\0' is 0
0 - The ascii value of 0 is 48

Answer / guest
ASCII value of 0 is 0,but ASCII value of '\0' is 27.

Answer / salim
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.

NULL is an the empty value but 0(zero) is an one of the value

Answer / shashwat
Actually binary code of both are same.
0 -> 00000000 NULL
But when this 0 is included in a string or char as
char x = '0';
or char x[20] = "1230";
It is the character zero (not NULL). It has an ASCII of 48
and will be stored as
00110000.
That is why, they have created different zeroes to
represent either the character zero or ASCII value zero.

What is the difference b/w '\0' and NULL?
The first is the representation for the null character, i.e.,
a character with value zero. It is used as a string
terminator in C.
It is actually an "escape sequence" with an octal zero.
The second is a macro that resolves to a null pointer value.
In C source
code a literal zero is also converted into a null pointer
constant when
it occurs in a pointer context.
The first expression is of type int while the second is of a
pointer
type.
> In which case It is useful?
Use '\0' to terminate strings and NULL to initialise
pointers and set
them to a "safe" value after they have been used.

Answer / madhu
end of the string is indicated by \0 but 0 is a value
thus there is difference between them
| Is This Answer Correct ? | 2 Yes | 2 No |
