Answer to 1 and 2 and 3 with the 4 choices.

Which method do you invoke to:

1- create a list of strings called myStrings:

a - myNumbers.front();

b- myNumbers.addFront(15);

c- SLinkedList myStrings;

d- SLinkedList myNumbers;

2- add an integer 15 to the front of a singly linked list called myNumbers:

a - myNumbers.front();

b- myNumbers.addFront(15);

c- SLinkedList myStrings;

d- SLinkedList myNumbers;

3- return the front element of a singly linked list called myNumbers:

a - myNumbers.front();

b- myNumbers.addFront(15);

c- SLinkedList myStrings;

d- SLinkedList myNumbers;

Solution

1. c- SLinkedList myStrings;

To create a list of strings called myStrings the object myStrings of class SLinkedList is used;

2. b- myNumbers.addFront(15);

To add an integer 15 to the front of a singly linked list called myNumbers , the object myNumbers is used to invoke method addFront(15). The method will add the integer 15 to the front of the linked list myNumbers.

3. myNumbers.front();

To return the front element of a singly linked list called myNumbers, the front() is invoked by myNumbers object of class SLinkedList.
