The question as text
This pseudocode algorithm allows 5000 numbers to be entered and stored in an array called Number. FOR Count 1 TO 5000 INPUT Number[Count] NEXT Count Extend and re-write the algorithm using pseudocode to also count and output how many of the numbers stored in the array are greater than 500, using the variable Higher. Only output Higher once with an appropriate message. [6]

Any six from:
MP1
Initialisation of Higher to 0 before the loop
MP2
Use of IF statement
MP3
Correct condition in IF statement
MP4
Correct counting statement inside loop
MP5
OUTPUT/PRINT statement with correct reference to Higher MP6
Appropriate message in output
MP7
Correct location of OUTPUT and IF statements
Higher ← 0
FOR Count ← 1 TO 5000
INPUT Number[Count]
IF Number[Count] > 500
THEN
Higher ← Higher + 1
ENDIF
NEXT Count
OUTPUT "There are ", Higher, " values that are greater than 500"
