(->) arrow operator and (.) dot operator , class pointer

Question

In C++ we know that for a pointer of class we use (->) arrow operator to access the members of that class like here:

#include 
usi         


        

Answer 1

Note that for a pointer variable x

myclass *x;

• *x means "get the object that x points to"
• x->setdata(1, 2) is the same as (*x).setdata(1, 2) and finally
• x[n] means "get the n-th object in an array".

So for example x->setdata(1, 2) is the same as x[0].setdata(1, 2).
