Ok, I am trying to write a program that will print out a simple wordsearch (you know, a grid of random letters with several themed words hidden in it). I'd really like it finished before Christmas, so does anyone have an algorithm for placing the letters on the grid? A 2-dimensional character array would be fine for the grid, I have the printing part done and dusted.

The list of words is already known to the program at runtime, the words will be no longer than 20 characters, and the grid will be about 25 grid squares in width and height.

I would like it to have words horizontally and vertically, diagonally would be brilliant, but not neccesary.

I'm not going to have much time to work on this myself which is why I'm asking here, normally I'd struggle through it myself

Its for a school by the way, which explains the title!
