Answer to Question #182631 in C++ for Ian

Question

Let’s make a program that calculates the age of your car!

We should ask the user to input the Make, Model, and the Year their car was made.

Our program should create a Car object and then calculate how old that car is by subtracting the year the car was made from the current year. (Example: 2021 - 2001 = 20 years old)

Coding Instructions:

Create a class called Car.

This class should have 3 member variables:

• a string called Make
• a string called Model
• an integer called Year

The class should have a function that returns the age of the car by subtracting the member variable "year" from the current year (2021).

The class should have a constructor that takes 3 parameters: make, model, year.

Example Output:

“Welcome to Historic Car Calculator”

“Please enter the make of your car.”

>>Honda

“Please enter the model of your car.”

>>Civic

“Please enter the year your car was made.”

>>1995

“Your Honda Civic is 26 years old”
