Question
Write a function calculateDriving Cost() with input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, that returns the dollar
cost to drive those miles. All items are of type double. If the function is called with 50.0 20.0 3.1599, the function returns 7.89975.
Define that function in a program whose inputs are the car's miles/gallon and the gas dollars/gallon (both doubles). Output the gas cost for
10 miles, 50 miles, and 400 miles, by calling your calculateDriving Cost function three times.
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.
Ex: If the input is:
20.0 3.1599
the output is:
1.58 7.90 63.20
Your program must define and call a function:
double calculateDriving Cost (double driven_miles, double miles_per_gallon, double
dollars_per_gallon);
