Chapter 8, Problem 10PE

Program Plan Intro

Fuel efficiency of a multi-leg journey

Program Plan:

• Declare the “MPG” function.
  • Assign the values to the variables.
  • Iterate the “for” loop until it reaches the last line in the text file.
    • Set the value.
  • Check “leg” is not equal to newline.
    • In “try” block,
      • Split the odometer reading and amount of gas from the user input and assign it into the separate variables.
      • Increment the “count” value.
      • Calculate the distance traveled, total distance.
      • Calculate the MPG for leg.
      • Set the new odometer reading.
      • Display the leg.
      • Add values to trip total.
      • Break the function.
        • In exception block, break the function.
        • Return the value to the main function.
• Declare a main function. Inside the main function,
  • Get the input file name from the user.
  • Open the file.
  • Get the starting odometer reading from the user.
  • Call the function “MPG”.
  • Calculate the total MPG.
  • Display the result.
• Call the main function.
