　　We've previously learned about Golang's basic data types, strings and Byte, and Rune, but it's possible that we're still not quite sure about the high-level data types, so learn these advanced data type data with my footsteps today. I believe that some people may have learned python, so I do not have to read this blog basically, because you will feel so easy. Because there are so many similarities, it's just a different notation. This chapter focuses on arrays, slices (scice), dictionaries (maps), structures (structs), and so on.

One. Arrays

1. Define an empty array

1 Package Main2 3 Import "FMT"4 5 Func Main () {6var num [3]int//indicates that an array with a capacity of 3 is defined, and if no initial value is assigned, the default is"0".7Fmt. Printf ("The first number of the array is:%d\n", num[0])8Fmt. Printf ("The last number of the array is:%d\n", Num[len (num)-1])9      forI,v: =Range num {TenFmt. Printf ("The subscript for the array is:%d, the initial value corresponding to the array's subscript is:%d\n", I,v) One     } A      for_,v: =Range num { -Fmt. Printf ("the initial value of the array is:%d\n", V) -     } the } -  -  -  + #The result of the above code execution is as follows: - The first number of the array is: 0 + The last number of the array is: 0 A The subscript of the array is: 0, the initial value corresponding to the array subscript is: 0 atThe subscript for the array is: 1, the initial value corresponding to the array's subscript is: 0 -The subscript for the array is: 2, the initial value corresponding to the array's subscript is: 0 - the initial value of the array is: 0 - the initial value of the array is: 0 -The initial value of the array is: 0
