Accessing an entire row of a multidimensional array in C++

Question

How would one access an entire row of a multidimensional array? For example:

int logic[4][9] = {
    {0,1,8,8,8,8,8,1,1},
    {1,0,1,1,8,8,8,1,1},
    {8,1,0         


        

Answer 1

As well as decaying the array to a pointer, you can also bind it to a reference:

int (&temp)[9] = logic[2];

One advantage of this is it will allow you to use it C++11 range-based for loops:

for (auto t : temp) {
  // stuff
}
