I am curious if there are common loop index variables (of single character or not) for dealing with 4 dimensions and above?
I was helping another student working through CS50x who was just learning about loops and she asked more or less "if x,y,z are standard for 3D axises with indexes i,j,k , respectively, what if there was a 4D matrix?" I guessed it would be "i,j,k,l" with x,y,z,w , (general form w-- and l++ for 5D etc) but I wanted to check what other people thought. I realise that at that point, it is uncommon enough that there isn't really any "standard", or complex enough that that the loops should be either simplified or the variables named better.
That said, are there "common" loop variable names for indexes in 4D and above?
