The following table lists C mathematical comparison operators.

Operator | Example | True When |
---|---|---|

!= | a != b | a is not equal to b |

< | a < b | a is less than b |

<= | a <= b | a is less than or equal to b |

== | a == b | a is equal to b |

> | a > b | a is greater than b |

>= | a >= b | a is greater than or equal to b |

Comparisons in C work from left to right.
