Fundamentals of Object-Oriented Programming - C++ - Templates - Class and Function

The video tutorial explains how to create a program that swaps two variables regardless of their type using a template class. It covers declaring a template, defining a swap function with a void return type, and performing the swap using a temporary variable. The tutorial also demonstrates printing the results to the console and running the program to observe the swapped values.

What is the primary purpose of using a template in the swap function?

• To make the function run faster

• To allow the function to swap variables of any type

• To simplify the syntax of the function

• To restrict the function to integer types only

Which operator is used to access the variables in the swap function?

• Dereference operator

• Address-of operator

• Increment operator

• Logical AND operator

What is the role of the temporary variable 'C' in the swap function?

• To hold the value of A temporarily

• To store the sum of A and B

• To calculate the difference between A and B

• To store the product of A and B

In the main function, what types of variables are swapped using the template function?

• Only string variables

• Both integer and string variables

• Only integer variables

• Only floating-point variables

What is the expected output after swapping the integer variables X and Y?

• X = 21, Y = 21

• X = 21, Y = 9

• X = 9, Y = 21

• X = 0, Y = 0
