我试图比较愤怒和双重:

printf("%d
", pos<(td+tr));
            if(td <= pos < (td+tr))
            {}

印刷说明对比较代码(>pos和(td+tr)if(td <=pos < (td+tr)的比较没有适当评价。

Pos is an int: int pos; td and tr are doubles: double td,tr;

最佳回答
td <= pos < (td+tr)

只评价正确。 因此,

td <= pos

对事实价值进行评估。 然后,这一真实价值与<代码>td+tr进行了比较。

这并不是你想要的。 你们想要

if (td <= pos && pos < td+tr)
问题回答

你的法典没有做你可能认为做的事情,或许需要你做。

td <= pos && pos < (td+tr)

?
