推荐答案
我假设 0
的意思是 false
(很多编程语言都是这样).这意味着 true
是 not 0
(有些语言使用 -1
有些其他语言使用 1
; 不会伤害到兼容).所以假设更好"意味着更少的打字,你可以写:
I assume 0
means false
(which is the case in a lot of programming languages). That means true
is not 0
(some languages use -1
some others use 1
; doesn't hurt to be compatible to either). So assuming by "better" you mean less typing, you can just write:
bool boolValue = intValue != 0;
