So I am getting 2 errors that I need help explaining. Here is both of them.

ANN.cpp: In member function ‘void ANN::JustDoIt()’:
ANN.cpp:36: error: ‘class std::vector<HiddenNeuron, std::allocator<HiddenNeuron> >’ has no member named ‘SetWeights’
ANN.cpp: In member function ‘void ANN::SetData(double, double)’:
ANN.cpp:85: error: ‘SetNeuronData’ was not declared in this scope

ANN.cpp: In member function ‘void ANN::JustDoIt()’:
ANN.cpp:36: error: ‘class std::vector<HiddenNeuron, std::allocator<HiddenNeuron> >’ has no member named ‘SetWeights’

You are trying to called SetWeights on your ANN::hidden vector. What exactly are you trying to do here?

ANN.cpp: In member function ‘void ANN::SetData(double, double)’:
ANN.cpp:85: error: ‘SetNeuronData’ was not declared in this scope

You are trying to push_back the results of some function SetNeuronData(), which doesn't exist.

Ok so I see what I did wrong for the second one but the first one confuses me still. I need to set the weights first so I was calling the function to set the weights but it says that it doesn't exist. why?\
