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

A direct assignment won't work. C++ does not allow that. At best you'll be able to assign them to point to the same data - int *temp = logic[2]. You'll need a for loop or something like the below.

I believe this would work:

int temp[9];
memcpy(temp, logic[2], sizeof(temp));

But I'd generally suggest using std::vector or std::array instead.
