如果（X == 0 || 7 || 14 || 21 || -7 || -14）{Y =周四;} [英] if (x==0||7||14||21||-7||-14) {y=THURSDAY;}

问题描述

您可以用一串或公司的一排这样？

Can you use a bunch of or's in a row like that?

 if (x==0||7||14||21||-7||-14){y=THURSDAY;}

它似乎并没有对我的工作。
怎么了？可以||不能用于两个否则，如果具有相同的则predicate条件

it doesn't seem to be working for me. what's wrong? Can || not be used for two else if conditions with the same then predicate?

推荐答案

被认为是逻辑真。所以你如果能读到这样：
如果x == 0或真或真或真...
你大概的意思是如果（X == 0 ||点¯x== || 7 ==点¯x14 ...）

in c anything other than 0 is considered boolean true. so your if can be read like: if x==0 or true or true or true... what you probably meant was if (x==0 || x==7 || x==14 ...)
