http://c.biancheng.net/golang/syntax/ Go语言变量的声明(使用var关键字) Go语言是静态类型语言,因此变量(variable)是有明确类型的,编译器也会检查变量类型的正确性。在数学概念中,变量表示没有固定值且可改变的数。但从计算机系统实现角度来看,变量是一段

In Go, the:=operator is a shortcut for declaring and initializing a variable in one line (Go uses the value on the right to determine the variable's type). Taking the long way, you might have written this as: 在Go中,:=操作符是在一行中声明且初始化变量的捷径(Go使用右边的值来推测变量...
