Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a C++ program that uses a while structure to input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tandful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls, Your output screen should somewhat look like the following: Enter the gallons used (-1 to end): 12.8 Enter the miles driven: 287 The miles/gallon for this tank was 22.421875 Enter the gallons used (-1 to end): 10.3 Enter the miles driven: 200 The miles/gallon for this tank was 19.417475 Enter the gallons used (-1 to end): 5 Enter the miles driven: 120 The miles/gallon for this tank was 24.0000 Enter the gallons used (-1 to end): -1 The overall average miles/gallon was 21.601423 Using a while loop statement and if statements to write a program that can be used at a department store's register that records the number of customers who spent between $0.00 - $200.00, $200.01 $800.00, $800.01 or more At the end of a day, the program will print out the number of customers in each of categories
