C++ sudoku coursework please help!!

Hey!

So we've started learning c++ only recently so Im still bit new to the syntax and they've given a coursework about making a sudoku game which I'm finding incredibly hard to get my head around it.

Anyone a bit of a wise owl in the subject ? Then I can go into the deets!
Thanks! :smile:

So, I'm using a 3D vector to make the puzzle. But I'm struggling with the algorithm for setting the value inside square in the board and removing all the other same values from the other boxes.

So I'm making a vector1<vector2<vector3<int> > > as the board.
Vector 3 is the values till 9 and then Im trying to remove all the other possibilities when 1 no. is selected.

So say your 3d vector is called vec.
And then the user picks x on the square with coordinates a and b. You want that squares respective vector to only contain the digit 1.
So you say:


vec[a] = {x};

And obviously it doesn't have to be 1, it could be any integer variable.

Then you loop through the whole row.
[code]
for (int i = 0; i
