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

This video tutorial introduces vectors in C++, explaining their dynamic nature compared to arrays. It covers how to declare vectors, use the push_back function to add elements, and iterate through vectors using a for loop. The tutorial also demonstrates modifying vector elements, including replacing and removing them with functions like pop_back. Additionally, it explains inserting and erasing elements using the insert and erase methods. The video encourages exploring more vector functions for future programming projects.

What is the main difference between a vector and an array in C++?

• Vectors are static, while arrays are dynamic.

• Vectors require more memory than arrays.

• Arrays can store different data types, while vectors cannot.

• Vectors can automatically resize, while arrays cannot.

Which library must be included to use vectors in C++?

How do you add an element to the end of a vector?

• Using the insert() function

• Using the push_back() function

• Using the add() function

• Using the append() function

What function is used to access the size of a vector?

• capacity()

• count()

• length()

• size()

How can you replace a value at a specific position in a vector?

• Directly accessing the position using an index

• Using the replace() function

• Using the modify() function

• Using the update() function

What does the pop_back() function do in a vector?

• Clears all elements

• Removes the last element

• Removes the first element

• Adds an element to the end

Which method is used to insert an element at a specific position in a vector?

• place()

• insert()

• add()

• push()
