I have this code but doesn't seem to give me the necessary output in cmd. The following are instructions i followed in order to create it.

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, up to twenty-four hour drive period, from an input file, bloodDrive.txt. The average pints, highest pints, and lowest pints donated during that period should be calculated and written to a file calledbloodResults.txt. We will only run the program once so a yes/no loop is not needed.

Step 1: Note that the getHigh, getLow, and getAverage functions do not change. We need to modify modules getPints and displayInfo to meet the new requirements. Complete the pseudocode below for the two modules according to instructions:

In the getPints Module (notice there is a new pass-by-reference parameter count)

Declare an input file with the name bloodInFile.

Open the internal file (bloodInFile) and a text file named bloodDrive.txt.

If cannot open file then display an error message

Set count = 0

Input one value from the file

While not end-of-file, store value in the array[count], add 1 to count, and input another value

Close the file.

Module getPints(Real pints[], Integer Ref count)

End Module

In the displayInfo Module

Declare an output file with the name bloodOutFile.

Open the internal file (bloodOutFile) and a text file named bloodResults.txt.

Write the string Report generated by [YourName] to the file.

Write the string Blood drive period: to the file.

Write the value of hours to the file.

Write the string Average Pints: to the file.

Write the value of averagePints to the file.

Do the same thing for highest pints and lowest pints

Close the bloodOutFile.

Module displayInfo(Integer hours, Real averagePints,

Real highPints, Real lowPints,)

End Module

Pseudocode for the main module (MAX_HOURS is a global named constant)

Module main()

//Declare local variables

Declare Real pints[MAX_HOURS]

Declare Integer hours

Declare Real avePints, highPints, lowPints

Call getPints(pints, hours)

Display hours: , hours

Set avePints = getAverage(pints, hours)

Set highPints = getHigh(pints, hours)

Set lowPints = getLow(pints, hours)

Call displayInfo(hours, avePints, highPints, lowPints)

End Module

Page BreakLab 9.2 Java Code

Convert the blood drive program from Lab 9.1 to Java code with the help of Java Companions Ch. 10. Create a text file name bloodDrive.txt in the project folder with the following values.

43

25

64

35

19

Run your program and check against the following output file, bloodResults.txt. If there are errors, go back through the steps to troubleshoot. You might want to output relevant information such as input data to the screen to see what is going on.

Report generated by [YourName]

Blood drive period: 7

Average pints: 38.4

Highest pints: 64.0

Lowest pints: 19.0

You might want to try another test case with fewer or more than 7 values to make sure your program can handle it. Dont forget to format the results properly.? When your code is complete and runs properly, print both the source code and the output file for the test case above.?
