The single 1D array is fine for a uniform rectangular grid, with rows being nothing more than an offset into the array. I hesitate to say any more though since it's a homework situation.

Re: random numbers, and 2 dimensional array 17 Years Ago by Ancient Dragon >>Of course, you cannot do this with columns. That's a problem for another day Sure you can -- if what you mean is you can not sort by columns rather than by rows. Its possible to sort all rows by a specific column or all columns by a specific row. Might not make much sense to do it, but it is possible.

As I noticed at your example the random numbers are from 1 to 9. Is that a requirement? Meaning do the numbers have to be from 1 to N*N? Re: random numbers into an array 16 Years Ago by Ezzaral You're on the right track generating the list of numbers 1 to N*N into an array and then shuffling them. You just need to consider how to pick a random place in the array to place each number.

Re: random numbers, and 2 dimensional array 17 Years Ago by sillyboy [CODE]cout << table[row][column];[/CODE] Are you sure this is what you want to be doing? In regard to implementing the random integers, you can just assign them as you print that particular cell. So add something before the above code. On a minor note, why are you creating an array of doubles? Re: random numbers, and 2 dimensional array 17 Years Ago by maxmaxwell You know how to populate a two dimensional array with an iteration(for, while etc.)statement right? Do it the same way, except set the values equal to random numbers instead.

I'm thinking I may have to script this in Python and use the original random list as a feedstock, then evalaute each one. Where it passes, send it to finallist, where it doesn't save it off to failed. Then at the end do again with everything in failed. I'll post here if I ever get it right.
