Initializing Array of Class Object in list

Question

Car is a template class, and its constructor is defined as follows:

template <class carObject>
explicit Car( const carObject & notFound, int size = 101 );
Car( const carObject & rhs )

In my header file (h), I have:

class Storage{
public:
    Storage();
    Car <char*> myCars[12];
};

In my CPP file (.cpp), I'm trying to initialize myCars array using initializing list as follow:

Storage::Storage()
: myCars("notFound", 20)
{ //my other stuff}

but I keep getting the error message:

error: invalid initializer for array member Car:myCars("notFound", 20)

Any help?

@TonyTheLion Storage::Storage is the class that has Car <char*> mycars[12] declared in — Andy_A̷n̷d̷y̷

@Andy the point is that it isn't obvious from your question. You need to add all relevant information to your question. — Tony The Lion

@Andy Don't do this. Make your question correct. There's no excuse for being lazy there. Just copy your actual code. Make it SSCCE. See also Nobody Writes Testcases Anymore and Solve your problem by almost asking a question on Stackoverflow. — sehe

Your array need 12 initializers like

template <typename T> struct Car {
    template <class carObject> explicit Car(const carObject &notFound, int size = 101) {}
};

struct Storage {
    Storage()
            : myCars{
                  Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 },
                  Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 },
                  Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 },
                  Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 }, Car<char *>{ "notFound", 20 },
              } {}
    Car<char *> myCars[12];
};

int main(){}

Of course you can leave out some initializers if the element type is default-constructible. But the structure of the initializer would need to match this structure
