Implement a C$++$ code that calculates the price of doing car maintenance. The program should take any needed input and the calculation is done as follows:

a$)$ A fixed value of $1000$ is needed for any car

b$)$ If the km are between $0-30,2\mathrm{.}5$ extra are payed for every km

c$)$ Il the km are between $30-50,3\mathrm{.}5$ extra are payed for every km

d$)$ If the km are between $50-70,4\mathrm{.}5$ extra are payed for every km

e$)$ If the km are between $70-90,5\mathrm{.}5$ extra are payed for every km

f$)$ If the km are between $90-120,7\mathrm{.}5$ extra are payed for every km

g$)$ If the km are more than, $9\mathrm{.}5$ extra are payed for every km

In addition, in case there is a problem with the wheels, the customer pays $1000$ extra for every wheel $($Hint: the user needs to enter the number of defected wheels$)$
