Question

This lab examines the various ways of working with arrays by writing pseudocode. Read the following programming problem prior to completing the lab.

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 displayed. Additionally, the highest and the lowest number of pints donated should be determined and displayed. Write a loop around the program to run multiple times.

Step 1: Declare the following:

• A global named constant MAX_HOURS with a value 7
• A local array named pints of the data type Real of size MAX_HOURS
• A local variable named averagePints of the data type Real
• A local variable named highPints of the data type Real
• A local variable named lowPints of the data type Real

// Declare global named constant below

____________________________________

Module main()

     //Declare local variables

     Declare String again = “yes”

     ____________________________________

     ____________________________________

     ____________________________________

     ____________________________________

     While again == “yes”

           // module calls below to be completed

           // in the next few steps

           Display “Do you want to run again (yes or no)? ”

           Input again

     End While

End Module

Step 2: Write a module call to a module named getPints that passes the pints array and the number of hours. Additionally, write a module header named getPints that accepts the pints array and number of hours.

                       

//Module call

Call ______________(______________, MAX_HOURS)

//Module header

Module __________(Real __________[ ] , Integer hours)

Step 3: Write a for loop inside module getPints that runs specified times using the counter variable and the two parameters. Inside the for loop, allow the user to enter values into the array.

                        Declare Integer counter = 0

           For __________________ = 0 to hours - 1

                Display “Enter pints collected:”

                Input ___________[_________]

           End For

Step 4: Write a function call to a module named getAverage that passes the pints array and the number of hours. Additionally, write a function header named getAverage that accepts the pints array and the hours variable.

                       

//Function call

Set averagePints = _____________(_____________, MAX_HOURS)

//Function header

Function _________(Real ______________[ ], Integer hours)

Step 5: Write a for loop inside function getAverage that runs hours times using the counter variable. Inside the for loop, total up the values of the array and store in the variable totalPints. Also, return the correct variable from the function.   

            Declare Integer counter

     Declare Real totalPints = 0

     Declare Real averagePints

     For __________________ = 0 to _______________

           Set _________ = ________ + ______________[________]

     End For

Set averagePints = ________________ / _________________

     Return _________________

Step 6: Write a function call to a module named getHigh that passes the pints array and the number of hours. Additionally, write a function header named getHigh that accepts the pints array and the hours variable.

                       

//Function call

Set highPints = ____________(______________, ___________)

//Function header

Function ______ _______( Real ________[ ], Integer _____)

Step 7: Write the code that will determine the highest value in an array. Also, return the correct variable from the function.   

Declare Integer index

Declare Real highest = pints[________]

For index = 1 to _____________

     If _______________[_______] > highest Then

           Set ____________ = __________[_______]

     End If

End For

Return ______________________

Step 8: Write a function call to a module named getLow that passes the pints array and the number of hours. Additionally, write a function header named getLow that accepts the pints array and the hours variable.

                       

//Function call

Set lowPints = ____________(______________, ___________)

//Function header

Function ______ _______( Real ________[ ], Integer _____)

Step 9: Write the code that will determine the lowest value in an array. Also, return the correct variable from the function. This function is very similar to getHigh function.

     _______________________________________________________

Step 10: Write a module call to a module named displayInfo. Pass the necessary variable to the functions that are needed to display the averagePints, the highPints, and the lowPints. Also, write the module header that accepts the same variables. Although pseudocode for this module is not required, but feel free to set it up.

            //Module call

Call displayInfo(______________, ___________, ___________)

//Module header

Module ________(Real ________, Real ________, Real _______)

Answer 1

Ans:

/*

The above program which is required to be developed is to be specified in an abstract psuedo-code format, filling the blanks being given in various steps:

*/

Step 1 (ans.)

Declare Const MAX_HOURS = 7
Module main()
   Declare String again = "yes"
   Declare Real pints[MAX_HOURS]
   Declare Real averagePints
   Declare Real highPints
   Declare Real lowPoints
   While again == “yes”
        // module calls below to be completed
        // in the next few steps
      Display “Do you want to run again (yes or no)? ”
       Input again
       End While
End Module

Step 2:

//Module call

Call getPints(Real pints[], MAX_HOURS)

//Module header

Module getPints(Real pints[ ] , Integer hours)

Step 3 :

Declare Integer counter = 0

For counter = 0 to hours - 1

Display “Enter pints collected:”

Input pints[counter]

End For

Step 4:

//Function call

Set averagePints = getAverage(Real pints[], MAX_HOURS)

//Function header

Function getAverage(Real pints[ ], Integer hours)

Step 5:

//Function call

Set averagePints = getAverage(Real pints[], MAX_HOURS)

//Function header

Function getAverage(Real pints[ ], Integer hours)

Step 6:

//Function call

Set highPints = getHigh(Real pints[], MAX_HOURS)

//Function header

Function getHigh( Real pints[ ], Integer hours)

Step 7 :

Declare Integer index

Declare Real highest = pints[0]

For index = 1 to hours

If pints[index] > highest Then

Set highest = pints[index]

End If

End For

Return highest

Step 8:

//Function call

Set lowPints = getLow(Real pints[], MAX_HOURS)

//Function header

Function getLow( Real pints[ ], Integer hours)

Step 9:

Declare Integer index

Declare Real lowest = pints[0]

For index = 1 to hours

If pints[index] < lowest Then

Set lowest = pints[index]

End If

End For

Return lowest

Step 10:

//Module call

Call displayInfo(Real averagePints, Real highPints, Real lowPints)

//Module header

Module displayInfo(Real averagePints, Real highPints, Real lowPints)
