C++ Array of Arrays, defining parts separately

I'm trying to make an array of arrays containing 2 lists of strings (one singular and one plural).

string item_name[2][6];
string item_name[0] = {"bag of CinnaCandies", "can of Arizona Tea", "Starbucks Mocha Frappe", "copy of Section 8: Prejudice", "Sushi Box", "pair of Nike Jordans"};
string item_name[1] = {"bags of CinnaCandies", "cans of Arizona Tea", "Starbucks Mocha Frappes", "copies of Section 8: Prejudice", "Sushi Boxes", "pairs of Nike Jordans"};

I don't know the proper syntax to do this and I'd like to keep it as an array of 2 arrays so I can have code that says:

if (quantity > 1)
    {
        cout << item_name[0][index];
    }
    else
    {
        cout << item_name[1][index];
    }

Thanks. :)

Both answers above are correct. In addition, you also can use something like this:

vector<string> item_name[2];

This way, you still have an array of "arrays" but the sub-array size is not fixed, so you can continue appending as many entries as you need.

And of course, you can also use the notation

item_name[0][index];

To get the "index" item at the first top-level array.

You're on the right track. You just need a single declaration, and nest the brackets so that you have an array of arrays:

string item_name[2][6] = {{"bag of CinnaCandies", "can of Arizona Tea",
                           "Starbucks Mocha Frappe", "copy of Section 8: Prejudice",
                           "Sushi Box", "pair of Nike Jordans"},
                          {"bags of CinnaCandies", "cans of Arizona Tea", 
                           "Starbucks Mocha Frappes", 
                           "copies of Section 8: Prejudice", "Sushi Boxes", 
                           "pairs of Nike Jordans"}};

Initialise normally, but instead of a regular constant you use a sub-array:

string item_name[2][6] = {
    {"bag of CinnaCandies", "can of Arizona Tea", "Starbucks Mocha Frappe", "copy of Section 8: Prejudice", "Sushi Box", "pair of Nike Jordans"},
    {"bags of CinnaCandies", "cans of Arizona Tea", "Starbucks Mocha Frappes", "copies of Section 8: Prejudice", "Sushi Boxes", "pairs of Nike Jordans"}
};
