Answer / susie
Answer :
1 2
Explanation:
The sizeof() operator gives the number of bytes
taken by its operand. P is a character pointer, which needs
one byte for storing its value (a character). Hence
sizeof(*p) gives a value of 1. Since it needs two bytes to
store the address of the character pointer sizeof(p) gives 2.

Answer / jha334201553
sizeof(*p) = sizeof(char) = 1
sizeof(p) = sizeof(void *)
I don't know the value of sizeof(p) .In deferent system the
value is deferent.In DOD, it's 2. int 32bits winNT, it's 4.
in 64bits WinNT, It's 8

Answer / dilberphant
The results are indeterminate. The program code is in error.
1) The variadic function printf() requires an in-scope
prototype. No prototype for printf() has been provided.
2) main() is (by definition) a function that returns an
integer value. It is unclear which version of the C language
this program is intended to conform to, and for most
versions of the language, main() is required to include a
return <value>;
for some integer <value>
3) In a hosted environment, main() accepts either two
arguments (an int, and a char *[]) or none. Thus, either
main(int argc, char *argv[])
or
main(void)
are acceptable
4) The size of a pointer is dependant on operating platform
and C compiler implementation. The C language does not
define a "correct" value for sizeof (char *), and thus /any/
value for sizeof (char *) is acceptable (with the above
caveats about platform and compiler). The value is
unpredictable at a theoretical level.

Write out a function that prints out all the permutations of a string. For example, abc would give you abc, acb, bac, bca, cab, cba. You can assume that all the characters will be unique.
