So I have a vector of bullets that show up on the screen and I do not want these bullets to live forever. I want them to "die as soon as they go off screen or collide with an enemy. How can I make sure they are removed from the array and no longer take up memory.

ie

std::vector<Bullet> bulletArray;

for(int i=0; i<bulletArray.size(); i++)
        {
            bulletArray[i].MoveBullet();
            bulletArray[i].Draw();
            if(bulletArray[i].PosY<0)
            {
                        //Delete object forever 
            }
        }
