array of pointers to an array of structures

how does i access the structure variable by using an array of pointers to that structure..... also the structure variable is an array in this case...

say for example

Code:

---

struct EMP
    {
        int no;
        char name[50];
        char add[100];
        char date[20];
    }emp[2], *ptr[2];

---

how do i access the name member of emp[1]??

You need to dereference the pointer, and then use a member operator. Since this is so common - a special operator exists that does both: ->

If emp[1] is a pointer to a struct, emp[1]->name returns the member name (but remember that it's going to return a pointer to the beginning of name - you can still access inidividual elements of that array by saying emp[1]->name[49], etc...)

These strcpy()s all do the same thing:

Code:

---

struct EMP
    {
        int no;
        char name[50];
        char add[100];
        char date[20];
    }emp[2], *ptr[2];

strcpy(emp[1].name, "Joe");
ptr[1] = &emp[1];
strcpy((*ptr[1]).name, "Joe");
strcpy(ptr[1]->name, "Joe");

got it!!! thanks
