The statements are fairly similar to their equivalent in other C-like languages, with some exceptions: +Go 提供了三个主要的控制了语句：`if`、`switch` 和 `for`。这些语句同其他 C 风格语言内的语句非常类似，但有一些不同： - * There are no parentheses around conditions, so it is `if a == b {}`, not `if (a == b) {}`. The braces are mandatory. + * 条件语句没有括号，所以条件语句是 `if a == b {}` 而不是 `if (a == b) {}`。大括号是必须的。 - * All of them can have initialisers, like this - -`if result, err := someFunction(); err == nil { // use result }` - - * The `switch` statement can use arbitrary expressions in cases - - * The `switch` statement can switch over nothing (equals switching over true) - - * Cases do not fall through by default (no `break` needed), use `fallthrough` at the end of a block to fall through. - - * The `for` loop can loop over ranges: `for key, val := range map { do something }` + * 所有的语句都可以有初始化，比如这个 + + `if result, err := someFunction(); err == nil { // use result }` + + * `switch` 语句在 cases 里可以使用任何表达式 + * `switch` 语句可以处理空的表达式（等于 true） + * 默认情况下，Go 不会从一个 case 进入下一个 case（不需要 `break`），在程序块的末尾使用 `fallthrough` 则会进入下一个 case。 + * 循环语句 `for` 不止能循环值域：`for key, val := range map { do something }` ### Goroutines
