You can actually declare in C synonyms using special syntax that says, you know what, even though yes at the end of the day I'm implementing false as a 0 and true as a 1, I can abstract away from that detail and use words that are more intuitive to me like true and false.

实际上，你可以用C语言中的特定的语法,你们懂得，虽然到最后,我把0当成假，1当成真来看，我们也可以从这些细节中抽象出来,使用像“真““假“这样更直观的词。
