Problem while initializing attribute in constructor c++

While i try to debug ERROR appear : "Unhandled exception at 0x5784F2F6 (ucrtbased.dll) in Final project.exe: An invalid parameter was passed to a function that considers invalid parameters fatal." Tried every thing can't figure out how to solve this.

using namespace std;
class Map :
{
private:
    double *mhours_played;
    string *maps;
    unsigned element_num;
public:
    Map() 
    {
         maps[2] = { "Summoner's rift", "Aram" };
         element_num = 2; mhours_played[2] = {};
    }

    ~Map() { delete[] maps; }
};

These statements

maps[2] = { "Summoner's rift", "Aram" };
mhours_played[2] = {};

do not make sense. maps and mhours_played are pointers that within the body of the constructor have indeterminate values. They are not arrays as you think. For example the expression maps[2] is a scalar object of the type std::string.

Define the constructor at least like

Map() :  mhours_played( new double[2]() ), 
         maps( new std::string[2] { "Summoner's rift", "Aram" } ),
         element_num( 2 )
{
}

and the destructor like

~Map() 
{ 
    delete[] maps; 
    delete[] mhours_played;
}
