Fundamentals of Object-Oriented Programming - C++ - Header Files

The video tutorial explains how to implement arithmetic operations using functions in a program. It covers defining functions for addition, subtraction, multiplication, and division, and replacing hard-coded operations with function calls. The tutorial highlights the benefits of using functions, such as reusability and modularity, and demonstrates how to organize code by creating and using header files for function declarations.

Why do we use float as the return type for arithmetic functions?

• To avoid using integers

• To simplify the code

• To make the functions run faster

• To ensure compatibility with both integers and floating-point numbers

What is the main purpose of replacing hard-coded operations with function calls?

• To reduce the number of lines in the code

• To make the code look more complex

• To increase the execution time

• To allow for easier reuse of code

What is one advantage of using functions in programming?

• They allow for code reuse in different parts of the program

• They increase the size of the program

• They make debugging more difficult

• They make the code harder to read

How can separating function logic into different files benefit a program?

• It reduces the need for comments

• It makes the program run slower

• It helps in organizing the code and makes debugging easier

• It increases the complexity of the program

What is the purpose of a header file in C++?

• To include libraries

• To organize function declarations and important algorithms

• To store the main function

• To execute the program

How do you include a header file in a C++ program?

• By copying the file content into the main file

• By using the 'include' keyword with double quotes

• By using the 'require' keyword

• By using the 'import' keyword

What is the result of organizing code with header files?

• The program size increases

• The code is cleaner and easier to maintain

• The program runs faster

• The code becomes more difficult to understand
