Hi syed110,

suppose you have
struct a {
   int b;
   char c;
   int d;

struct a * p;
struct a st;

p = &st;

to store values in this struct using the pointer

p->b = 10;
p->c = 'a';
p->d = 25;

replace the RHS values with the values you have read from the file

What objects are you talking about? do you have objects containing the structures?

And if u want to create an instance of the structure at runtime, after creating the pointer variable p,

p=new (struct a);

Happy Programming!
