2. Computer Science 2 Today:
Understand how to save different kinds of information about a person in a record.
On the record (paper) write the following
Name:______________
Farthest from Salem:____________
Favorite Food: _____________
Favorite College: _____________
Top three college majors:_______________

3. What would you use if…
You needed to store someone’s name, age, and phone number?
What about name, strength, skills and position?
What about a recipe: Title, Ingredients, instructions, …
How about a song title, length of the song, artist name, ranking on your personal favorites list, …
Pascal has a ‘data structure’ that can store more than one type of information in a single variable.

4. Program RecordsExample; type StudType = record name:string;
age:integer;
gpa:real;
end;
var
Student1,Student2:Studtype;
begin
writeln(‘Please enter your name’);
readln(Student1.name);
writeln(‘Please enter your age’);
readln(Student1.age);
writeln(‘Please enter another name’);
readln(Student2.name);
writeln(‘Please enter another age’);
readln(Student2.age);
if (Student1.age) > (Student2.age) then
writeln(Student1.name,’ is older’)
else
writeln(Student1.name, ‘ is not older ‘);
end.
Student1
Name:________
Age:_________
GPA:_________
Student2

5. Declarations and stuff
In the Type section
Rectype = record
Field1:field1type;
Field2, field3:field23type; …
End;
In the Var section
Recordvariable:Rectype;
In the Code Section
Recordvariable.Field1:=…;

6. What do you think this will do?
Program RecordsExample;
type
StudType = record
name:string;
age:integer;
gpa:real;
end;
var
Student1,Student2:Studtype;
begin
writeln(‘Please enter your name’);
readln(Student1.name);
writeln(‘Please enter your age’);
readln(Student1.age);
writeln(‘Please enter another name’);
readln(Student2.name);
writeln(‘Please enter another age’);
readln(Student2.age);
if (Student1.age) > (Student2.age) then
writeln(Student1.name,’ is older’)
else
writeln(Student1.name, ‘ is not older ‘);
Writeln(Student);
end.
Common errors
Putting a ; here
Forgetting the ‘end.’
What do you think this will do?

7. Write the declarations (Type and var) for a variable that needs to hold…
Team Name, School, Total score (For a swim meet, wrestling meet, track meet, …)
Project Leader name, Three goals (Sentences), Money allocated for the project, Project due date.
Student name, Student ID number, Class schedule.

8. First Record Program
Input an unknown number of Team Names, School names, and Total scores. (While loop)
Output: The winning team. That is the team with the highest score. (If there is a tie, just show the first team with the top score.)
(Note, you don’t need an array for this program.)
Push: Same input as above, and show the schools with the top five scores. (You do need an array and a sort for this one.)
