是否可以将三元运算符作为for循环的终止符? [英] Is it possible to fit in a ternary operator as the termination in a for loop?

问题描述

所以，我只想知道是否有可能在for循环的终止位内插入任何代码或三元运算符.如果有可能，您能否在for循环中提供一个三元运算符的示例?谢谢！

So, I just want to know if its possible to slip in any code or a ternary operator inside the termination bit of a for loop. If it is possible, could you provide an example of a ternary operator in a for loop? Thanks!

for (initialization; termination; increment) {
   statement(s)
}

推荐答案

for语句中的termination子句(如果提供-它实际上是可选的)可以是您想要的任何表达式，只要它的结果为boolean.

The termination clause in the for statement (if supplied - it's actually optional) can be any expression you want so long as it evaluates to a boolean.

它必须是一个表达式，而不是一个任意代码块.

It must be an expression, not an arbitrary code block.
