Given main$(),$ complete the Car class $($in files Car.h and Car.cpp$)$ with member functions to set and get the purchase price of a car $($SetPurchasePrice$(),$ GetPurchasePrice$()),$ and to output the car's information $($PrintInfo$()).$

Ex: If the input is:

$2011$

$18000$

$2018$

where $2011$ is the car's model year, $18000$ is the purchase price, and $2018$ is the current year, the output is:

Car's information:

Model year: $2011$

Purchase price: $18000$

Current value: $5770$

Note: printInfo$()$ should use three spaces for indentation.
