This initialization is done recursively, so for instance each element of an array of structs will have its fields zeroed if no value is specified. 据此我们可总结出: 对于值类型:布尔类型为 false, 数值类型为 0,字符串为 "",数组和结构会递归初始

对于复合类型, go语言会自动递归地将每一个元素初始化为其类型对应的零值。 比如:数组, 结构体 。 原文: When storage is allocated for avariable, either through a declaration or a call ofnew, or when a new value is created, either through a composite literal or a call ofmake, and no explicit...
golang中的map,的 key 可以是很多种类型,比如 bool, 数字,string, 指针, channel , 还有 只包含前面几个类型的 interface types, structs, arrays。显然,slice, map 还有 function 是不可以了,因为这几个没法用 == 来判断,即不可比较类型。 可以将map[map[string]string]int改为map[struct]int。 本文参与...

structs computer spec.go main.go 1.9 结构体比较 结构体是值类型,如果每个字段具有可比性,则是可比较的。如果它们对应的字段相等,则认为两个结构体变量是相等的。 示例代码: package main import ( "fmt" ) type name struct { firstName string lastName string } func main() { nam...

5. Arrays and Slices: `array`, `slice` 6. Maps: `map` 7. Structs: `struct` Variables and Constants You can declare variables and constants in Golang using the `var` and `const` keywords respectively. Here is an example: ```
The literal syntax is similar for arrays, slices, maps, and structs (数组、slice、map和结构体字面值的写法都很相似). The common form of arrays is a list of values in order, but it is also possible to specifya list ofindexand value pairs, like below: ...
