Checkpoint Week 7 Chapter 5 Essay Example
Analysis:
Process: 1. Open “GRADES” file 2. Display StudentName 3. Display TestScores 4. Add TestScores 5. Display Sum
Input:
StudentName As String Test1 As Integer Test2 As Integer Test3 As Integer Sum As Integer
Output:
Display all three TestScores and the Sum
Problem 1:
Input names of students from the user, terminated by ZZZ, and create a data file GRADES with records of the form: student(string), test1(integer), test2(integer), test3(integer). In this file, all test scores should b e set equal to 0.
Main Module
Declare StudentName As String Declare Test1, Test2, Test3 as Integers Open “GRADES” Call WriteGrades Module Close “Grades”
End Main Module
WriteGrades Module Declare StudentName As String Declare Test1 As Integer Declare Test2 As Integer Declare Test3 As Integer Open “GRADES” For Output As TestScores Set Test1, Test2, Test3 = 0 Display “Enter student’s name and test scores separated by a comma.” Display “Enter ZZZ for student’s name when you are finished.” Display “ To move on to the next student entry hit the enter key.” Input StudentName, Test1, Test2, Test3 While StudentName <> “ZZZ” Display TestScores, StudentName, Test1, Test2, Test3 Display “Enter student’s name and test scores separated by a” Display “comma” Display “Enter ZZZ when you are finished.” Input “ZZZ”
End While
Close TestScores
End WriteGrades Module
Problem 2:
Display the contents of the file GRADES created in Problem 1. Each student’s record should appear on a separate line and include the total score (the sum of the three tests) for that student. For example a line output might be:
R. Abrams 76 84 82 242
