What is the primary concept introduced in the video regarding functions?

• Function overloading

• Function inheritance

• Function polymorphism

• Function encapsulation

When defining functions with the same name, what is crucial to differentiate them?

• The return type

• The number of arguments

• The function name

• The function visibility

What property should a function have if it returns a sum and does not modify the state?

• View

• Pure

• Private

• Public

How do you ensure that a function returns the correct sum of its arguments?

• By using global variables

• By hardcoding the values

• By correctly specifying the arguments

• By using a loop

What is the main advantage of function overloading demonstrated in the video?

• It simplifies the code by reducing the number of functions

• It allows functions to have the same name but different arguments

• It enables functions to handle different types of data

• It allows functions to have different names

How does the program determine which overloaded function to execute?

• By the function name

• By the number of arguments

• By the return type

• By the function's visibility

What is the term used to describe having multiple functions with the same name but different parameters?

• Function inheritance

• Function overloading

• Function encapsulation

• Function abstraction
