10.array 是值类型, 作为参数其值不会被改变, 形参复制了一份数据给实参; 如果确实需要改变, 需要使用数组指针 或者 slice切片作为形参: Array Function Arguments 11.for range 遍历返回两个参数k, v, 不是一个参数: Unexpected Values in Slice and Array "range" Clauses 12.慎用 多维数组、多维slice,需要...
We call theaddfunction; it takes two parameters. The computed value is passed to thezvariable. func add(a int, b int) int { return a + b } We define theaddfunction. The parameters of the function are separated with comma; each parameter name is followed with its data type. After the...
