Question
Last year, a local college implemented rooftop gardens as a way to promote energy efficiency and save money.
Write a program (flowchart AND pseudocode) that:
• Allows the user to enter the energy bills from January to December for the year prior to going green.
• Allows the user to enter the energy bills from January to December of the past year after going green.
• The program should calculate the energy difference from the two years, month by month, and display the two years’ worth of data, along with the savings.
• Additionally, the savings array should be recorded (written) to a file called savings.txt.
Explanation / Answer
The American Red Cross wants you to write a program that will calculate the average pints of blood donated during a blood drive. The program should take in the number of pints donated during the drive, based on a seven hour drive period. The average pints donated during that period should be calculated and written to a file. Write a loop around the program to run multiple times. The data should be appended to the file to keep track of multiple days. If the user wants to print data from the file, read it in and then display it. Store the pints per hour and the average pints donated in a file called blood.txt.
External Design
When the user specifies to print the data, the following should be displayed:
Pints Each Hour
##
##
##
##
##
##
##
Average Pints
##.##
Step 1: Note that the getPints, getTotal, and getAverage functions do not change. Also note that the references to displayInfo, getHigh, and getLow functions are removed to meet the new requirements. In the pseudocode below, add the following:
In the Main Module
In the writeToFile Module
In the readFromFile Module
Module main()
//Declare local variables
Declare String again = “yes”
Declare Real pints[7]
Declare Real totalPints
Declare Real averagePints
a. _________________________________________
While again == “yes”
//module calls below
Display “Enter 1 to enter in new data and store to file”
Display “Enter 2 to display data from the file”
Input b. ______________________________
c. If _____________ == _________________ Then
pints = getPints(pints)
totalPints = getTotal(pints, totalPints)
averagePints = getAverage(totalPints, averagePints)
d. Call _____________(__________,________)
Else
e. Call _____________(__________,________)
End If
Display “Do you want to run again: yes or no”
Input again
End While
End Module
Module getPints(Real pints[])
Declare Integer counter = 0
For counter = 0 to 6
Display “Enter pints collected:”
Input pints[counter]
End For
End Module
Function getTotal(Real pints[], Real totalPints)
Declare Integer counter = 0
totalPints = 0
For counter = 0 to 6
totalPints = totalPints + pints[counter]
End For
Return totalPints
Function getAverage(Real totalPints, Real averagePints)
averagePints = totalPints / 7
Return averagePints
Module writeToFile(Real pints[], Real averagePints)
f. Declare _________ ____________ ____________
g. Open _________________ ____________________
h. Write _______________ “__________________”
Declare Integer counter = 0
i. While counter < 7
Write __________ _________[_________]
counter = counter + 1
End While
j. Write ____________ “_____________”
k. Write ____________ ________________
l. Close __________________
End Module

The last item in this function is toclosetheoutFile.This is done asfollows:outFile.close()Step 12:Under the documentation and the function header for thereadFromFilefunction, create aninFileand call the open function.Pass this function the name ofthe text file and open it inreadmode.This should look as follows:inFile = open('blood.txt', 'r')Step 13:Next, read in the string ‘Pints Each Hour’ and print this to the screen.This isdone as follows:str1 = inFile.read()print str1Step 14:Read in the pints array as an entire list and print this to the screen.This is doneas follows:pints = inFile.read()print pintsprint#adds a blank lineStep 15:Read in the string ‘Average Pints’ and print this to the screen.Step 16:Read in averagePints and print this to the screen.Step 17:Close the inFile.Step 18:Run your program and for the first execution, select option 1.Run the programmore than once and enter at least 2 sets of data.
