## What are Precedence and Associativity?

Precedence and Associativity are the rules that are used to determine the **operators** with the highest priority in evaluating an equation that contains different operations.

For **example**:

1 | x = 10 + 5 * 2; |

In this example, x is assigned as 20, not 30 that’s because operator * has higher precedence than +, and hence it first gets multiplied (5*2) and then multiplied value is added to 10.

## In the following table, the precedence of an operator decreases from **top to down**:

Category | Operator | Associativity |
---|---|---|

Postfix | >() [] . (dot operator) | Left to right |

Unary | >++ – – ! ~ | Right to left |

Additive | >+ – | Left to right |

Relational | >> >= < <= | Left to right |

Additive | >+ – | Left to right |

Equality | >== != | Left to right |

Bitwise AND | >& | Left to right |

Bitwise OR | >| | Left to right |

Bitwise XOR | >^ | Left to right |

Logical AND | >&& | Left to right |

Logical OR | >|| | Left to right |

Conditional | ?: | Right to left |

Assignment | >= += -= *= /= %= >>= <<= &= ^= |= | Right to left |
