Question

I want an example showing how I can insert an 2D int array in another 1D int array? I am in a dead end here.

Answer 1

// 2D int array
typedef std::vector<std::vector<int> > twoDarray;

// 1D array **of 2D arrays, not ints **
std::vector<twoDarray> oneDarray;

// Instance of 2D array
oneDarray myOneDArray;

// Instance of 2D array
twoDarray myTwoDArray;

// Add this in.
myOneDArray.push_back(myTwoDArray);
