Hello @kailash_01,

  1. You use this->data_member_name, to access the data members of the class.
    No, it is not mandatory to use this.
    But, it is useful when the parameters have the same name as that of the class data member.
    this-> will help to distinguish between the data member and the local parameter of the function.

  2. You can use any of the two if they are successfully imitating the operation of queue.

Hope, this would help.
Give a like if you are satisfied.
