C Language Operators

In programming with C, you occasionally want to use common mathematical operators for common mathematical functions and not-so-common operators for logic and sequence functions. Here's a look at C language operators to use:

Operator, Category, Duty	Operator, Category, Duty	Operator, Category, Duty
=, Assignment, Equals	!=, Comparison, Is not equal to	>, Bitwise, Shift bits right
+, Mathematical, Addition	&&, Logical, AND	~, Bitwise, One's complement
–, Mathematical, Subtraction	||, Logical, OR	+, Unary, Positive
*, Mathematical, Multiplication	!, Logical, NOT	–, Unary, Negative
/, Mathematical, Division	++, Mathematical, Increment by 1	*, Unary, Pointer
%, Mathematical, Modulo	--, Mathematical, Decrement by 1	&, Unary, Address
>, Comparison, Greater than	&, Bitwise, AND	sizeof, Unary, Returns the size of an object
>=, Comparison, Greater than or equal to	|, Bitwise, Inclusive OR	., Structure, Element access
<, Comparison, Less than	^, Bitwise, Exclusive OR (XOR or EOR)	->, Structure, Pointer element access
<=, Comparison, Less than or equal to	<<, Bitwise, Shift bits left	?:, Conditional , Funky if operator expression
==, Comparison, Is equal to
