C++ Developer - Function Overloading

The video tutorial covers scopes and variable lifetimes, focusing on global, local, and static variables. It introduces function overloading, a feature in C, and guides viewers through creating a project to demonstrate this concept. The tutorial includes a challenge to add a new function overload and provides a solution walkthrough, emphasizing the importance of function signatures in distinguishing overloads.

What determines how long a variable exists in memory?

• The lifetime of the variable

• The name of the variable

• The type of the variable

• The scope of the variable

What is function overloading?

• Creating functions with the same name and same parameters

• Creating functions with different names and different parameters

• Creating functions with the same name but different signatures

• Creating functions with different names but same parameters

Which of the following is NOT part of a function's signature?

• Return type

• Number of parameters

• Type of parameters

• Order of parameters

In the example project, what does the function getresult(int, int) return?

• The division of two integers

• The difference of two integers

• The product of two integers

• The sum of two integers

How can you create a new overload of a function?

• By changing the function's scope

• By changing the number or type of parameters

• By changing the function's name

• By changing the function's return type

What is the result of calling getresult(5) in the extended project?

• 15

• 5

• 125

• 25

What is function binding?

• The process of linking a function call to its definition

• The process of linking a function to its scope

• The process of linking a function to its return type

• The process of linking a function to its parameters
