I've an array of pointers to structure. Can i initialize all them to NULL as below??
struct hash
{
int bid;
struct hash *prev,*next,*fl,*fr;
};
struct hash *h[4]={NULL,NULL,NULL,NULL};
one NULL (or one 0) will be enough since 0 is converted to NULL when assigned to pointers
struct hash *h[4] = {0};
additional info: first element will be initialized to the first value supplied. rest will get 0 according to standards. which part, section of standards? i have no idea but you can find it somewhere in the standards.
Yes!
T *t[] = {NULL, NULL};
Works for each T
.
你也可以使用
struct hash *h[]={0,0,0,0};
I think it will work
int main()
{
struct hash
{
int bid;
struct hash *prev,*next,*fl,*fr;
};
struct hash *h[5]={0};
