What does (->) does? Please with code example

[Akshit]

As we use . operator with class or structure or any other user defined data type.

-> operator is used with pointer of those data types

eg

struct str{
   int a;
};

//in main
str aa;
aa.a=5;
str *p=&aa;
p->a=5;

[Catfish4]

Following Akshit's example, it basically means:

(*p).a = 5;
p->a = 5; // less to write and clearer

Accessing member of object via pointer to that object is one place, but C++11 has also suffix return type syntax, where -> is used.
