A composite data type based on C + + learning go language-data type

This article discusses composite data types. Compound data types in C + + have only arrays and structs, and go adds two composite data types, slice and map. There is almost no difference between the array and struct in go and the C + +, which is the aggregation structure. Arrays are composed of homogeneous elements, which are composed of heterogeneous elements, both of which have a fixed size of memory. Slice and map are dynamic data structures that will grow dynamically as needed. This article begins with a brief discussion of the differences between the array and struct and C + + usages in Go, then discusses slice and map in detail, and finally shows how to use structs to decode and encode data in JSON format, and generate HTML pages by using templates together.
