Question 26

Study the algorithm shown in Figure 1.

1  tempReadings ← [18.5, 20.1, 24.6, 19.0]
2  errorDetected ← false
3  index ← 0
4  WHILE index < 4 AND errorDetected = false
5      IF tempReadings[index] > 24.0 THEN
6          errorDetected ← true
7      ELSE
8          index ← index + 1
9      ENDIF
10 ENDWHILE

State the data type of the variable errorDetected in the algorithm.
