[Dev-C++] elements from an array of pointers...

[senem b. <sbe...@ya...>]

when i try to get the elements back from a function i wrote, i get an error called "access violation" and i don't know what that is.i'd be glad if anyone who has time would look at it...i'm sending one part of the code, the one which doesn't work... 
kind regards...
