5.11 LAB: User-Defined Functions: Driving cost
Define a function named DrivingCost with parameters drivenMiles, milesPerGallon, and dollarsPerGallon, that returns the dollar cost to drive those miles. All items are of type float.
Ex: If the function is called with:
50 20.0 3.1599
the function returns:
7.89975
Write a main program whose inputs are the car's miles/gallon and the gas dollars/gallon (both floats). Output the gas cost for 10 miles, 50 miles, and 400 miles, by calling function DrivingCost three times.
Output the cost with two digits after the decimal point, which can be achieved as follows: Put cost to output with 2 decimal places
Ex: If the input is
20.0 3.1599
the output is:
1.58 7.90 63.20
Note: Small expression differences can yield small floating point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. In the DrivingCost function, use the variables in the following order to calculate the cost: drivenMiles, milesPerGallon, dollarsPerGallon.
