I can post more code if needed, but my problem is this: although it compiles nice, the array changes inside of the algorithm class. The values are different. Thank you in advance for any direction

private:
int array[];

has no meaning. You have to give the array a size or else you have to dynamically allocate it.

*array = *a1_Arr;

will copy only 1 element from the array.

thanks- i changed it to a dynamically allocated array and that solved my problems
