You could write a function like:


int** create_2d_array(int rows, int cols)
{
int** array = new int*[rows];

for (int i = 0; i < rows; i++)
array[i] = new int[cols];

return array;
}

//...

int** array = create_2d_array(5,5);
array[0][0] = 1;
array[3][4] = 1;
//etc


Replacing int with ...

Is this the correct way to use sort?


//include files (iostream, algorithm, vector, etc.)
class C
{
//...stuff
bool operator < (const C& r) const
{
if (some_attribute < r.some_attribute)
return true;
else
return false;
}
}

int main()
{
///
vector<C> units;
load_units(units);
sort ...

Like some people said in other threads, I my AC programs gives
1 11 3 13 9 0 12 17 16 3 19 18 22 3 23 29 0
for the test case stated in the problem.

I solved it by printing the x,y coordinates of the corners in the generated image, which isn't what is described by the problem but it gives an ...
