Hello!!
I am not able get many points in the Queue portion why we are using the this-> here. front is the not pointer type then also arrow operator is user with the pointer type object or data .
Implementation Of Circular Array Based Queue - [C++]
Hello @sudhanshu8917,
The dot and arrow operator are both used in C++ to access the members of a class. They are just used in different scenarios.
- a.b is only used if b is a member of the object (or reference[1] to an object) a. So for a.b, a will always be an actual object (or a reference to an object) of a class.
- a->b is essentially a shorthand notation for (*a).b, ie, if a is a pointer to an object, then a->b is accessing the property b of the object that a points to.
So, we use -> arrow if the object of the class is itself a pointer variable irrespective of the data members.
Hope, this is clear now.
