代码说话. use std::thread; use std::sync::mpsc; use std::time::Duration; fn main() { let (tx, rx) = mpsc::channel(); let tx1 = mpsc::Sender::clone(&tx); thread::spawn(move || { let vals = vec![ String::from("hi"), String::from("from"),…
挂羊头卖狗肉蓄意欺骗读者——谭浩强<C程序设计(第四版)>中所谓的“按照C99”(二) 在<谭C>p4:“本书的叙述以C99标准为依据”,下面从C89到C99的主要变化方面来看看是不是这样. <谭C>(前言)p12: ① 数据类型介绍中,增加了C99扩充的双长整型(long long int).复数浮点型(float complex,double complex ,long long complex).布尔型(bool)等,使读者有所了解. 实际上,C99不但增加了l…
