Classes - Data Member Help!!

[giraffe1234]

I've been trying to figure out this error for a while and am totally blanking on what is going wrong. I keep getting a data member initialization error. Below are two separate chunks of code where the error is occurring.

 class GA
{
private:

    /* GA parameters */
    double mutationRate = 0.015;
    int tournamentSize = 5;
    bool elitism = true;

public:

class Tour
{
private:
    //holds our tour of cities
    vector<City> tour;
    double fitness=0;
    double distance=0;
    TourManager tourManager;

I feel I'm missing some basic principle of why you can't do this, but I've been racking my brain on this project for a week now and still can't figure out this error. If I can't initialize the values here where do I initialize them?

you can, using the c++11 standard

in the constructor
