Operator Description Example
Unary Operators
* Indirection operator int x = *y;
& Address of operator int* x = &y;
~ Bitwise NOT x &= ~0x02;
! Logical NOT if (!valid) {...}
++ Increment operator x++; (same as x = x + 1;)
-- Decrement operator x--;
Class and Structure Operators
:: Scope resolution MyClass::SomeFunction();
-> Indirect membership myClass->SomeFunction();
. Direct membership myClass.SomeFunction();
As you can see, the list of operators is a bit overwhelming, so don’t worry about trying to
memorize each one. As you work with C++ you will gradually learn how to use all of the
operators.
It should be noted that in some cases an operator can be used either pre-increment (++x) or
post-increment (x++). A pre-increment operator tells the compiler, “Increment the variable’s
value and then use the variable.” A post-increment operator tells the compiler, “Use the
variable first and then increment its value.” For example, this code
int x = 10;
cout
