This article mainly introduces the relevant knowledge of "how to do errors in Go language variable declaration". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to do Go language variable declaration errors" can help you solve the problem.

If the variable has already been declared with var, and then declared with: =, a compilation error is generated in the format:

V_name: = value

For example:

Var intVal int intVal: = 1 / / A compilation error will occur at this time, because intVal has already declared that there is no need to redeclare

You can simply use the following statement:

IntVal: = 1 / / there is no compilation error at this time, because a new variable is declared, because: = is a declaration statement

IntVal: = 1 equals:

Var intVal int intVal = 1

You can abbreviate var f string = "Runoob" as f: = "Runoob":

Example

Package main

Import "fmt"

Func main () {

F: = "Runoob" / / var f string = "Runoob"

Fmt.Println (f)

}
