structure initialization

The output of the code has to be zero, but I am having an error, please guide. I can initialize the structure with its type variable but how can I do with the pointer to initialize the whole structure?

#include<stdio.h>
typedef struct student
{
 int roll_id[10];
 int name_id[10];
 int postn;
} student;
int main()
{
 student p; /// here i can do student p={ {0} };
 student *pptr=&p;
 pptr= { {0} }; /// but can i initialize in this way ?? //error: expected 
 expression before ‘{’ token
 pptr->roll_id[9]=1;
 printf (" %d\n", pptr->postn); 
 return 0;
}

  • I think it's valif IF he can do it with the variable. "student p; /// here i can do student p={ {0} };", just wanted to explain the mechanics. Commented Jan 8, 2013 at 11:05
