Marcus wants to program a temperature calibration simulator for a smart thermostat.

The program will generate a random target temperature between 15 and 30 inclusive.

The user must guess the target temperature to calibrate the sensor.

This pseudocode contains the logic required to run the simulator.

1  #   Initialise variables
2      SET attempts TO 1
3      SET target TO RANDOM(15) + 15    # i.e. a random integer 15 to 30 inclusive
4      SET guess TO 0
5
6  #   Print prompt and take guess from user
7      SEND "Enter a target temperature from 15 to 30: " TO DISPLAY
8      RECEIVE guess FROM (INTEGER) KEYBOARD
9
10 #   Create while loop to check guess
11     WHILE guess <> target DO
12         SET attempts TO attempts + 1
13         IF guess > target THEN
14             SEND (guess & " is too high. Try cooling it down.") TO DISPLAY
15         ELSE
16             SEND (guess & " is too low. Try heating it up.") TO DISPLAY
17         END IF
18         SEND "Adjust temperature: " TO DISPLAY
19         RECEIVE guess FROM (INTEGER) KEYBOARD
20     END WHILE
21
22 #   Report correct temperature and attempts
23     SEND ("Correct! Target of " & guess & " degrees reached in " & attempts & " attempts.") TO DISPLAY
