i have a string related doubt ?

Question

this code works fine :-
int main(int argc, char **argv)
{
char *str;
scanf("%s", str);
printf("%s", str);
return 0;
}

But not this WHY :-

int main(int argc, char **argv)
{
char *str[5];
scanf("%s", str[0]);
printf("\n%s", str[0]);
return 0;
}

pls, help here to let me understand difference
i know that second code declares an 5 string pointers.
but what then?

Answer 1

codemonkey
i tried this on my pc and it worked thats why i have this doubt in the first place
but now it is quite clear to me that i can not scan values in uninitialized situation
however if i assign values like
char *str ;
str ="hello";
str= "world";
it works fine because str changes its value and now it is pointing to "world".
i just want to clear that AM I RIGHT ?

Answer 2

codemonkey thanks i have this cleared in my mind i want to know that just right .
