What I am doing is filling a 2-D array with numbers in a random order.
i.e. I pick a position in the 2-D array and input a number there
eg: array = 3;(this input is received from a text file)
In this way, I fill the array but some spots remain empty.
What I want to do is fill these empty position in the 2-D array with the number 99, but I don't know how to go through the array and test if each position is empty.
I tried going through the array and comparing each position to null but that didnt help, it gave me a "incomparible type" error.
Can someone help me?
