Structs and pointers
- by user1763861
I have a few questions about structs and pointers
For this struct:
typedef struct tNode_t {
char *w;
} tNode;
How come if I want to change/know the value of *w I need to use t.w = "asdfsd" instead
of t->w = "asdfasd"?
And I compiled this successfully without having t.w = (char *) malloc(28*sizeof(char));
in my testing code, is there a reason why tt's not needed?
Sample main:
int main()
{
tNode t;
char w[] = "abcd";
//t.word = (char *) malloc(28*sizeof(char));
t.word = w;
printf("%s", t.word);
}
Thanks.
