[Decisions/If Statements & Loops]

(50 Points)

Please do the following exercises:

1. Pastoral College is a small college in the Midwest. Design the pseudo-code for a program that accepts a student name, major field of study, and grade point average. Display a student’s data with the message “Dean’s list” if the student’s grade point average is above 3.5, “Academic probation” if the grade point average is below 2.0, and no message if the grade point average is between 2.0 and 3.5 inclusive.

2. The Summerville Telephone Company charges 20 cents per minute for all calls outside the customer’s area code. All other calls are 15 cents per minute. Design the pseudo-code for a program that accepts data about a phone call: customer area code (three digits), customer phone number (seven digits), called area code (three digits), called number (seven digits), and call time in minutes (four digits). Display the calling number, called number, and price for the call.

3. Design an application that will convert either Fahrenheit to Celsius or Celsius to Fahrenheit. Have the user enter a 1 to convert Fahrenheit to Celsius and a 2 for Celsius to Fahrenheit. If the user enters any other number, output an error message. Once the user enters a 1, do the input, calculation and output for a Fahrenheit to Celsius conversion. If the user enters a 2, do the input, calculation and output for a Celsius to Fahrenheit conversion. Also write the pseudo-code.

4. Design an application that will Calculate the area of a Shape. Have the user enter a “C” to use a Circle, an “S” to use a Square and an “R” to use a Rectangle. If the user enters any other letter or number, output an error message. Once the user enters a “C”, do the input, calculation and output to Calculate the area of a Circle. If the user enters an “S”, do the input, calculation and output to Calculate the area of a Square. If the user enters an “R”, do the input, calculation and output to Calculate the area of a Rectangle. Also write the pseudo-code.

5. Design the pseudocode/flowchart for a program that outputs numbers in reverse order from 10 down to 1. Your output should go to the console window. Use a loop with step -1.

6. Design the pseudocode/flowchart for a program that uses a while loop to output numbers between 0 and 100, stepping by 5. (ie. 0, 5, 10, 15…) Your output should go to the console window.

7. Write the pseudo-code/flowchart for an application that calculates the Celsius equivalent to Fahrenheit Temperatures. The Fahrenheit temps should start at 0 and go up to 300, incrementing 20 each time through the loop.(Formula is: Celsius = (Fahrenheit-32.0) * (5.0/9.0)). Your output should be displayed on the Console Window. Don’t worry about formatting the Celsius data.

Sample Output:

Fahrenheit Celsius

0. -17.8

20. -6.7

40. 4.4

300. 148.9

Answer 1

Pastoral College is a small college in the Midwest. Design the pseudo-code for a program that accepts a student name, major field of study, and grade point average. Display a student’s data with the message “Dean’s list” if the student’s grade point average is above 3.5, “Academic probation” if the grade point average is below 2.0, and no message if the grade point average is between 2.0 and 3.5 inclusive.

PSEUDOCODE STUDENT()

1. Input Student Name to NAME
2. Input the Major_field to MAJOR
3. Input the grade_point to GPA

7. If(GPA > 3.5)

Write : “Dean’s List”

Else If(GPA <2.0)

     Write : “Academic Probation”

[End of If]       

8. RETURN

The Summerville Telephone Company charges 20 cents per minute for all calls outside the customer’s area code. All other calls are 15 cents per minute. Design the pseudo-code for a program that accepts data about a phone call: customer area code (three digits), customer phone number (seven digits), called area code (three digits), called number (seven digits), and call time in minutes (four digits). Display the calling number, called number, and price for the call.

PROCEDURE PHONE_CALL()

1. Input Customer area code to Ccode
2. Input Customer Phone Number to Cphone
3. Input Called area code to Call_Code
4. Input Called Phone Number to Call_Phone
5. Input Call time to Ctime
6. Write : “Customer Number” + Ccode+Cphone
7. Write : “Called Number “+Call_Code+Call_Phone
8. Write : “Call Time “+ Ctime
9. If(Ccode = Call_Code)

Price = Ctime * 15

Else

Price = Ctime * 20

          [end of if]

10. Write : “Call Charge “ + Price + “Cents”
11. Return

If the user enters any other number, output an error message. Once the user enters a 1, do the input, calculation and output for a Fahrenheit to Celsius conversion. If the user enters a 2, do the input, calculation and output for a Celsius to Fahrenheit conversion. Also write the pseudo-code.

PSEUDOCODE TEMPERATURE()

1. Write : “1. Fahrenheit to Celcius 2. Celsius to Fahrenheit”
2. Input Choice to ch
3. If(ch=1)

Input “Temperature in Fahrenheit” to temp

Celcius = (temp – 32) /1.8;

Write : “Temperature in celcius “ + Celcius
