In C++ if you Get() a member pointer and then check if it's null before you use it (which is probably quite a common occurrence) and you're using two lines to do it in, you can save a line by testing the result of the assignment inline.
Player player1 = PlayerManager.GetPlayer(1);
if (player1 != NULL)
{
player1.doStuff();
}
becomes:
if (Player player1 = PlayerManager.GetPlayer(1))
{
player1.doStuff();
}
