What is this??
EDIT:
I tried using C style arrays and I get an error that says:
|
error: cannot convert 'double*' to 'double' in assignment

should i convert the smart pointer to a regular ptr?
You shouldn't be using std::array in the first place. They aren't resizable.
You should use vectors instead.
You also shouldn't hijack other people's threads asking for help.

Sorry about that.. I was desperate for answers :/
Any ways, in the pointer declaration do I do double or double[]?
You don't do a pointer declaration at all.
Just #include <vector>
Do vector<double> arr;
