Go 语言没有 while 和 do...while 语法,这一点需要同学们注意一下,如果我们需要使用类似其它语 言(比如 java / c 的 while 和 do...while ),可以通过 for 循环来实现其使用效果。 while 循环的实现 Ø 说明上图 1) for 循环是一个无限循环 2) break 语句就是跳出 for 循环 Ø 使用上面的 while
i, j := l-1, r+1 // 两个指针,因为do while要先自增/自减 for i < j { // 每次迭代 for { // do while 语法 i++ // 交换后指针要移动,避免没必要的交换 if q[i] >= x { break } } for { j-- if q[j] <= x { break } } if i < j { // swap 两个元素 q[i], q...

go主要是去掉了的继承实现相关的关键字。 去掉了do-while结构,和for功能上重复。 go语言中直接将将多线程的实现作为了关键字。也可见go的并发编程是他的杀手锏。 go去掉了异常处理相关的。 几个陌生的关键字 go中有几个关键字还是比较陌生,先简单看下,以后也会专门写文章 go go中的多线程编程称为goroutine,目...

rather than directly from the function updating the value. In this next release, this will permit the garbage collector to mediate writes to the heap while it is running. This change has no semantic effect on programs in 1.4, but was included in the release to test the compiler and the ...
