Function Practice Questions

These questions are based on the lessons from the textbook and are designed to help you practice writing and using functions in C++. Once you finish, make a post in the community with your .cpp file included to get peer feedback.

Question 1

Create a function called welcome that doesn't return anything and doesn't take any parameters.

Inside the function, print this message: Hi there! This is a custom greeting.

Use a function prototype above main() and define the body of the function below main().
Call the function from main() to make sure it runs and prints the message.

Question 2

Create a function called addFive that takes an int as a parameter and returns the value plus 5.

In main():

• Call addFive and pass in the number 10

• Store the returned value in a variable

• Print the result

You should see the value 15 printed when the program runs.

Question 3

Create a function called addTax that takes in a double value and returns it increased by 13 percent (multiple by 1.13).
