Code:
char x[10]={0x0};

According to C99 standard all of the 10 elements of x are set to zero. Unless you are using ancient Solaris compilers or something.... try it with this junk code in debug mode:
edit: see para 21 in section 6.7.8 of C99 standards.
Code:
void foo(void)
{
    int b[3]={0};
    char c[4]={0x0};
	/* this point */
}

int main()
{ 
    foo(); 
    return 0;
}

break on the line # for /* this point */

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)... (11 Replies)

NAME
puts, fputs - put a string on a stream SYNOPSIS
#include <stdio.h> int puts(const char *s); int fputs(const char *s, FILE *stream); DESCRIPTION
The puts() function writes the string pointed to by s, followed by a NEWLINE character, to the standard output stream stdout (see Intro(3)). The terminating null byte is not written. The fputs() function writes the null-terminated string pointed to by s to the named output stream. The terminating null byte is not writ- ten. The st_ctime and st_mtime fields of the file will be marked for update between the successful execution of fputs() and the next successful completion of a call to fflush(3C) or fclose(3C) on the same stream or a call to exit(2) or abort(3C). RETURN VALUES
On successful completion, both functions return the number of bytes written; otherwise they return EOF and set errno to indicate the error. ERRORS
Refer to fputc(3C). USAGE
Unlike puts(), the fputs() function does not write a NEWLINE character at the end of the string. ATTRIBUTES
