I have an issue with understanding array; ive ask my tutor/lect to explain it to me but they rant on another level and thats not helpful to me so I hope somebody here will - especially the last part at the bottom where it ask "// if the pixel for this row and column is a 1"... I am not sure what to put in that section.. any help would be great - ive attached the assignment sheet for reference

this is my assignment so far:
