At ping, why do we have to do array copying instead of passing on the source array that the client sent to us?
So I have been googling about this OpenSSL heart-bleed thing and somehow sees that it is caused by the heartbeat extension which requires client to ping the server to show its aliveness and it all comes to this memcpy function in C which is meant to copy from the source array to the destination array with the user specified size.

Data structure for grid with negative indeces
Sorry if this is an insultingly obvious concept, but it’s something I haven’t done before and I’ve been unable to find any material discussing the best way to approach it.

A vector of pointers to different derived classes of the same base class
I am writing a game in C++ which has different enemy types. I have defined a base Enemy class and I also have derived classes enemy1, enemy2 etc.
Now for updating these enemies in each iteration of the game, I want to have an array: EnemyArray with its elements pointing to the existing enemies so that I can make sure to update them all with their own version of update(), etc.
