$7\mathrm{.}19$ LAB$*$: Program: Fancy car

Program Specifications Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.h declares the functions necessary to complete the exercise. FancyCar.cpp provides the function stubs. Follow each step to gradually complete all functions in FancyCar.cpp$.$

Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main$()$ function includes basic function calls. Add statements in main$()$ as functions are completed to support development mode testing.

Step $0.$ In FancyCar.h$,$ declare private members for miles driven as shown on the odometer $($int$),$ gallons of gas in tank $($double$),$ miles per gallon or MPG $($double$),$ driving capacity $($double$),$ and car model $($string$).$ Note the provided constant variable indicates the gas tank capacity of $14\mathrm{.}0$ gallons.

Step $1(2$ pts$).1)$ Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is $24\mathrm{.}0,$ and the model is "Old Clunker". $2)$ Complete the second constructor by passing the model $($string$)$ and miles per gallon $($double$),$ and initializing all other private members the same as the default constructor. $3)$ Complete the accessor functions to check the odometer, check the gas guage, get the model, and get the miles per gallon. Submit for grading to confirm $2$ tests pass.

Step $2(1$ pt$).$ Complete the HonkHorn$()$ function to output the car model. If the car model is:

Honda Civic

the HonkHorn$()$ function outputs:

The Honda Civic says beep beep!

Submit for grading to confirm $3$ tests pass.

Step $3(1$ pt$).$ Complete the Drive$()$ function. Miles driven should increase by parameter distance, and the amount of gas should decrease by distance $/$ MPG$.$ Variables are only updated if parameter distance is positive. Submit for grading to confirm $4$ tests pass.

Step $4(2$ pts$).$ Complete the AddGas$()$ function. Increase gas tank by parameter amount only if parameter is positive. Set gas tank to FULL$\_$TANK if too much gas was added. Submit for grading to confirm $5$ tests pass.

Step $5(2$ pts$).$ Update the Drive$()$ function to identify if the car runs out of gas. If so$,$ the parameter distance will not be achieved, and the gas tank will have $0\mathrm{.}0$ gallons. Ex: Drive$(100)$ will not be possible with only three gallons of gas and MPG of $20\mathrm{.}0.$ The maximum driving distance is $60$ miles with three gallons of gas and MPG of $20\mathrm{.}0.$ Therefore, the odometer will only increase by $60$ instead of the requested $100,$ and the gas tank will have $0\mathrm{.}0$ gallons $($not a negative amount$).$ Submit for grading to confirm $6$ tests pass.

Step $6(2$ pts$).1)$ Add a boolean private data member in FancyCar.h to indicate if the car engine is on or off. $2)$ Complete the StartEngine$()$ function to set the boolean variable to true. $3)$ Complete the StopEngine$()$ function to set the boolean variable to false. $4)$ Update the constructors to start with the engine off. $5)$ Update the Drive$()$ function to only update private members if the engine is on$,$ and the engine turns off if the car runs out of gas. $6)$ Update the AddGas$()$ function to only add gas if the engine is off. Submit for grading to confirm all tests pass.
