C++, with vector<int[2]> can I push_back({someNum1,someNum2})?

c++, push-back, vector

Solution

Built-in arrays are not Assignable or CopyConstructible. This violates container element requirements (at least for C++03 and earlier). In other words, you can't have `std::vector` of `int[2]` elements. You have to wrap your array type to satisfy the above requirements.

As it has already been suggested, `std::array` in a perfect candidate for a wrapper type in C++11. Or you can just do

struct Int2 {
  int a[2];
};

and use `std::vector<Int2>`.

Problem

I have the vector: ``` vector<int[2]> storeInventory; //storeInventory[INDEX#]{ITEMNUM, QUANTITY} ``` and I am wanting to use the `push_back()` method to add new arrays to the inventory vector. Something similar to this: ``` const int ORANGE = 100001; const int GRAPE = 100002 storeInventory.push_back({GRAPE,24}); storeInventory.push_back{ORANGE, 30}; ``` However, when I try using the syntax as I have above I get the error `Error: excpeted an expression`. Is what I am trying just not possible, or am I just going about it the wrong way?
