Quick Questions
Shade in the A or B circle for each question.
1. Does a function header specify the data type of each parameter?
2. Does a function header include the data type of its return value?
3. Should the parameters and return type be separated by a colon?
4. Should data types like INTEGER be written in uppercase?
5. Would a function returning TRUE or FALSE use INTEGER as its return type?

Q5
A — False
Section B: Match the Pairs
Q1
define addNumbers(a: INTEGER, b: INTEGER): INTEGER → A function header with two integer parameters and an integer return type
Q2
: BOOLEAN → Indicates the function returns a TRUE or FALSE value
Q3
The data type describing a parameter or return value in a function header → INTEGER
Q4
A colon used just before the return type in a function header → define greet(name: STRING): STRING
Q5
define greet(name: STRING) STRING
return "Hello " + name
end function → The header is missing the colon before the return type
Q6
define square(num): REAL
return num * num
end function → The parameter num is missing its data type

Q1
A — The header is missing the colon before the return type — it should read (name: STRING): STRING.
Q2
B — Assignment in pseudocode uses ←, not <-.
Q3
C — A function definition must close with end function, not end func.
Q4
D — The parameter num is missing its data type — it should read (num: REAL).
Q5
A — Data types should be written in uppercase, such as INTEGER, not lowercase integer.
