Complete a program that has a user enter a pollutant choice, a number of grams of the

pollutant emitted per mile, and an odometer reading $(0-100000).$

Output an indication of whether or not they are compliant with the following regulations:

first $50,000$ miles second $50,000$ miles

carbon monoxide $3\mathrm{.}4$ grams$/$mile $4\mathrm{.}2$ grams$/$mile

hydrocarbons $0\mathrm{.}31$ grams$/$mile $0\mathrm{.}39$ grams$/$mile

nitrogen oxides $0\mathrm{.}4$ grams$/$mile $0\mathrm{.}5$ grams$/$mile

non$-$methane hydrocarbons $0\mathrm{.}25$ grams$/$mile $0\mathrm{.}31$ grams$/$mile

A sample run is shown here:

Your program must

$1.$ Not change any of the given code.

$2.$ Use the defined constant variables for any constant values in your program.

$3.$ Create additional constant variables to use when checking the mileage

boundaries $(50000$ miles and $100000$ miles$).$

$4.$ Output an indication that an invalid odometer reading has been entered $($outside

of the range of $0-100000).$

$5.$ Use the switch statement started in the program for your decision structure.

$6.$ Have at least one other user defined function. One possibility is the following

function that determines the allowable level for a particular pollutant:

double getAllowableLevel $($double gramsPerMileAllowed$1,$ double

gramsPerMileAllowed$2,$ int odometer$)$;
