Need help with C2676: binary '['... ERROR

[TaytayB]

Anytime I try to access part of an array, ba[index] for example, It gives me this error, even when I print out.

C2676: binary '[' : 'BitArray' does not define this operator or a conversion to a type acceptable to the predefined operator

class

[pogrady]

only predefined types have the [] operator built into the behavior. If BitArray is a class that you created, you will need to overload the operator.
