How to pass an empty array to a map?

Here is my question.

private:
map<string,int &> days;
int daysHours[6] = {};

I have private data like this.

void Schedule::studentSchedule()
{
    getDays().insert(pair<string, int&>("Monday", daysHours));
    getDays().insert(pair<string, int& >("Tuesday", daysHours));
    getDays().insert(pair<string, int&>("Wednesday", daysHours));
    getDays().insert(pair<string, int& >("Thursday", daysHours));
    getDays().insert(pair<string, int&>("Friday", daysHours));

    map<string, int&>::iterator it;
    for (it = getDays().begin(); it != getDays().end(); ++it)
    {
        cout << "Day: " << it->first << "\tHours: " << it->second << endl;
    }
}

I this function I want to create a map with days and empty array.

When I do that I am getting an error like this.

error: no matching function for call to 'std::pair<std::__cxx11::basic_string<char>, int&>::pair(const char [7], int [6])'
 getDays().insert(pair<string,int &>("Monday",daysHours));

Can you help me about that?
