### Geometry in Programming

Imagine you have a 2d plane in C++, where the X go from 0 to MaxX (there is no negative X) and a Y go from 0 to MaxY (go down, not up like normal irl geometry, and no NegativeY)

so you would have something like this:
For example MaxX = 6, MaxY = 4

So as you can see there is a total of MaxX * MaxY square, which is 24 (0 to 23)

Assuming each square is 32x32

How would u write a function that give the coordinate of each square given their ID (number between 0 - 23)? write it dynamically

I tried but it didnt work this is what i got:

 ``1234567891011`` ``````void Tile::CalXY() { int MaxTilePerRow = TILE_WIDTH / 32; int HowManyRow = TILE_HEIGHT / 32; int foo = TileID / HowManyRow; int bar = TileID % HowManyRow; box.x = bar * 32; // this is the X coordinate box.y = foo * 32; // this is the Y coordinate. Time 32 because each box is 32 apart }``````
 ``12345`` `````` int column = id % maxX ; int row = id / maxX ; box.x = column * 32 ; box.y = row * 32 ;``````

Using TILE_WIDTH and TILE_HEIGHT in place of the magic number 32 in the last two lines would be better but, given your attempt, I'm not certain exactly what they're supposed to represent.
