(Practice)

a. Write, compile, and run a C++ program that displays the following prompts:

Enter the miles driven:

Enter the gallons of gas used:

After each prompt is displayed, your program should use a cin statement to accept data from the keyboard for the displayed prompt. After the number for gallons of gas used has been entered, your program should calculate and display the miles per gallon (mpg). This value should be included in a message and calculated by using the formula miles per gallon = miles / gallons used. Verify your program by using the following test data:

Test data set 1: miles = 276, gas = 10 gallons

Test data set 2: miles = 200, gas = 15.5 gallons

After finishing your verification, use your program to complete the following chart. (Make sure to convert the miles driven to kilometers driven and gallons used to liters used, and then compute the kilometers per liter.)

Miles Driven	Gallons Used	Mpg	Km Driven	Liters Used	Km/L
250	16.00
275	18.00
312	19.54
296	17.39

b. For the program written for Exercise a, determine how many verification runs are required to make sure the program is working correctly, and give a reason to support your answer.
