'…' is not a type c++ compilation error

Question

I am writing a small game for an assignment and it requires using a map, I have successfully put the map into a 2d array, but now working further into the assignment I found I need to access the array Map[][] in another function. I have tried to get it to work but failed. The error I get with g++ is " error: 'Map' is not a type " Any help would be appreciated.

I have searched but either I am terrible at using the search engine or I couldn't find anything specific to this error.

const int MapSZ = 10; //In Global
int Map[MapSZ][MapSZ]; // Also Global

void GetMap(ifstream&, int); //Getting the map (Proto)

GetMap(fin, Map[MapSZ][MapSZ]); //In the main function.

void GetMap(ifstream& fin, Map[MapSZ][MapSZ]) //Inserting the map into an array

Answer 1

void GetMap(ifstream& fin, Map[MapSZ][MapSZ]) 

should be:

void GetMap(ifstream& fin, int Map[MapSZ][MapSZ]) 
                           ^^^^

Notice, that Map is the name of the array, but you didn't mention its type .

Answer 2

If Map[MapSZ][MapSZ] is defined as a global, as your comment states (ie it is defined in main.cpp but outside of the main function), there is no need to pass it as a parameter to GetMap . You could simply do something like

void GetMap(ifstream& fin); //proto

int main(int argc, const char * argv[]) {
    GetMap(fin);
}

void GetMap(ifstream& fin) {
    //some code that uses Map[MapSZ][MapSZ]
}
