For the below code why it is getting a white space when trying to print c1 and nothing is printed for c2?

Code:

int main(void)
{
       char c1='\0';
       char c2[]="\0";
       printf("h%cello\n",c1);
       printf("h%sello\n",c2);
       getch();
       return 0;
}

o/p: h ello(white space is there as it is '\0')
hello (white space is not there why???)

Because '\0' is a character like any other character. When you print this character you see an empty space. For a string, the situation is different -- a string that begins with '\0' is a string of zero length, and thus nothing at all is displayed.

For c1, you are literally seeing what a '\0' "looks like"

Yeah, the null character's interesting; it's tripped me up in the past when I've encountered 'em in the *nix world.

That being said, it's not necessary for our latest assignment; if you're going for the homework early, go you! If not, carry on; it's interesting.
