pointer

void main() { int a={1,2,3,4,5,6,7,8,9,10}; int *p=a; int *q=&a; cout<<q-p+1<<endl; } The output is 10, how? if we give cout<<q it will print the address, value won't print.... if we give cout<<p it will print the address, value won't print.... p has the base addr; q...

pass a pointer-to-pointer, or return a pointer?

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it: (1) one is to pass a pointer-to-pointer parameter, like: int my_malloc(int size, char **pmem) { *pmem=(char *)malloc(size); if(*pmem==NULL)...

wctomb

wctomb(3int)															      wctomb(3int)

Name
       wctomb - converts a character of type wchar_t to a multibyte character.

Syntax
       #include <stdlib.h>

       int wctomb (s, wchar)
       char *s;
       wchar_t wchar;

Arguments
       s       The s argument is a pointer to the resulting multibyte character object.

       wchar   The wchar argument is a value of type wchar_t.

Description
       The function determines the number of bytes needed to represent the multibyte character corresponding to the character code of type wchar_t
       whose value is wchar.  It stores the multibyte character representation in the array object pointed to by s (if s is not a  null  pointer).
       At most MB_CUR_MAX characters are stored.  This function is affected by the LC_CTYPE category of the current locale.

Return Value
       If s is a null pointer, the function returns a zero value.  If s is not a null pointer, the function returns:

	  o  - -1, if the value of wchar does not correspond to a valid multibye character

	  o  The  number  of  bytes  that  comprise the multibyte character corresponding to the value of wchar.  In no case is the value returned
	     greater than the value of the MB_CUR_MAX macro.
