1The .* operator is used to dereference pointers to class members.

1// Operators are simply functions but cooler
2// E.g: The + sign is an operator, [] is an operator, you get the point
3// Which is even cooler is you can overload them
4// Means you can change their behavior
5// I can make + actually decrement (dont do this)
6int operator+(int other){
7	return *this - other;
8}
9// And make - return always 0
10int operator-(int other){ return 0; }
11// (THIS IS ANOTHER PROGRAM SO + AND - ARE NOT BROKEN ANYMORE)
