A case study of structural grammar in go language _golang

This example describes the structural grammar in the go language. Share to everyone for your reference. The specific analysis is as follows:

The structure grammar represents the new allocation of a struct by the value of the Structure field as a list.
Use the Name: syntax to list only some of the fields. (The order of the field names is irrelevant.) ）
The special prefix & constructs a pointer to the structure grammar.

Copy Code code as follows:

Package Main
Import "FMT"
Type Vertex struct {
X, Y int
}
VAR (
p = vertex{1, 2}//has type Vertex
Q = &vertex{1, 2}//has type *vertex
r = vertex{x:1}//y:0 is implicit
s = vertex{}//x:0 and y:0
)
Func Main () {
Fmt. Println (P, Q, R, s)
}
