Hey guys,

I'm writing a search algorithm in C++, and one of the things I need to do is have a few if statements that check cells above, below, left of, and right of.

Each time a cell is found to be open and added to the stack, I want it added to a list of cells already checked.

I want to be able to say in the if loop if(thisCell is not in checkedCells).

Any simple ideas?

Thanks!
