Why am I unable to use a variable when using the map() function?-CodePudding

int main()
{
    unsigned int num = 2;
    string map[num][3] = {{"c","d","s"}, {"A", "u", "p"}};
    for(int y = 0; y < 2; y  )
            {
                for(int x = 0; x < 3; x  )
                {
                    cout << map[y][x];
                }

                cout << endl;
            }
}

I'm using Xcode and it gives me an error saying "Variable-sized object may not be initialized". Am I simply doing it wrong or is the map function unable to take in variables as arguments?

CodePudding user response：

You can declare an array only with constant size, which can be deduced at compile time.

source: variable-sized object may not be initialized c

SO, change the line:

unsigned int num = 2;

to this:

unsigned const num = 2;
