Driving costs (with pointers)
Complete the program below using pointers.

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved by executing
cout << fixed << setprecision(2); once before all other cout statements. This line is included for you.

Ex: If the input is:

20.0 3.1599
the output is:

3.16 11.85 79.00
Note: Real per-mile cost would also include maintenance and depreciation.
