Global variable

Variables declared outside the function are called global variables, which can be used in the entire package or even the external package (after being exported).

Global variables can be used in any function, and the following example demonstrates how to use global variables:

Example

Package main

Import "fmt"

/ * declare global variables * /

Var g int

Func main () {

/ * declare local variables * /

Var a, b int

/ * initialization parameters * /

A = 10

B = 20

G = a + b

Fmt.Printf ("result: a =% d, b =% d and g =% d\ n", a, b, g)

}

The output of the above example is as follows:

Results: a = 10, b = 20 and g = 30 is about the content of this article "Go language global variable instance analysis". I believe everyone has a certain understanding.
