SDD - Reading Code 2

Re-write the numbered pseudocode using techniques to make it more readable.

Name the variable in the program and state its data type.

• temp int

• heater string

• temp real

• heater boolean

What kind of statement is Lines 4-9 of the program

• Assignment

• Iteration

• Selection

• Concatenation

Using values in variables, describe the purpose of Lines 11-14.

Identify the line number(s) where a logical operator is used in this program

• Lines 5, 12 & 16

• Line 5

• Line 2, 5, 12 & 16

• Line 7

Describe in your own words what the program does.

The way that the code has been written is not particularly efficient.

Re-write the code using more efficient constructs to achieve the same outcomes.

The temperature reading should be between 0 and 50 during normal running of the sensor. What standard algorithm could be used to ensure that the value form the sensor remains in a valid range?

• Running Total

• Find Minimum

• Input Validation

• Traversing an array

The design technique for this program used in previous questions is

(a)  

Which of the following is NOT an example of a logical operator. Pick all that apply.

• AND

• &

• NOT

• >=
