Problem z kompilacją g++

Question

Witam, przerabiam podstawowy kurs budowania sieci neuronowych, ale mam pwien probem związany z kompilacją programu. Nie rozumiem co to za błęðy i czemu one wystepują.

Mój kod:

#include <vector>
#include <iostream>

using namespace std;

class Neuron{
public:

private:

}

typedef vector<Neuron> Layer;

class Net{
public:
        Net(const vector<unsigned> &topology);
        void feedForward(const vector<double> &inputVals);
        void backProp(const vector<double> &targetVals);
        void getResults(vector<double> &resultVals) const;
private:
        vector<Layer> m_layers;
};

Net::Net(const vector<unsigned> &topology){
        unsigned numLayers = topology.size();
        for(unsigned layerNum = 0; layerNum < numLayers; ++layerNum){
                m_layers.push_back(Layer());

                //We have made a new layer. Now fill it with neurons, and
                //add a bias neuron to the layer
                for(unsigned neuronNum = 0; neuronNum <= topology[layerNum]; ++neuronNum){
                        m_layers.back().push_back(Neuron());
                }
        }
}

int main(){
        //e.g. {3, 2, 1}
        //3 layers
        //first layer have 3 inputs
        //seckond have 2 hidden neuron
        //third have one output
        vector<unsigned> topology;
        Net myNet(topology);

        vector<double> inputVals;
        myNet.feedForward(inputVals);

        vector<double> targetVals;
        myNet.backProp(targetVals);

        vector<double>resultValu;
        myNet.getResults(resultValu);

return 0;
}

Błędy:

Z góry dziękuje za pomoc :D

Answer 1

Klasa Neuron nie powinna być zakończona średnikiem?

Nienawidzę takich głupich błędów xD Dzięki za pomoc, zaraz sprawdze i napiszę czy zadziałało :)

Dziełą, wielkie dizęki :D
