# 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 |
