Fundamentals of Object-Oriented Programming - C++ - STL - LIST

The video tutorial explains how to manipulate lists in programming, focusing on operations like pushing and popping elements from both ends of a list. It covers the use of iterators and methods to access list size. The tutorial also delves into advanced list functions such as reverse, merge, and unique, demonstrating how to handle duplicates and merge two lists. Practical examples are provided to illustrate these concepts.

What is a key feature of a list container that allows fast access to both ends?

• It is implemented as a stack.

• It uses a single pointer for navigation.

• It contains pointers to both the next and preceding elements.

• It stores the size of the list.

Which method is used to add elements to the back of a list?

• push_back

• pop_back

• insert

• push_front

How can you determine the number of elements in a list?

• Using the size method

• Using the count method

• Using the length method

• Using the total method

What is the purpose of the reverse function in list operations?

• To sort the list in ascending order

• To remove duplicate elements

• To reverse the order of elements in the list

• To merge two lists

What does the merge function do when applied to two lists?

• It combines the elements of both lists into one.

• It splits the lists into smaller lists.

• It removes duplicates from both lists.

• It sorts both lists in descending order.

Why did the unique method not work initially in the example?

• Because the lists were not merged.

• Because the reverse function was called before the unique function.

• Because the unique function was not defined.

• Because the lists were empty.

What happens when the unique function is applied after merging two lists?

• It removes duplicate elements, keeping only one instance.

• It sorts the list in ascending order.

• It removes all elements.

• It duplicates all elements.
