In Go, you can import code from another file by using the import statement. Here is an example of how to import a file named example.go and use a function named helloWorld from that file:
package main
import (
"fmt"
"./example"
)
func main() {
fmt.Println(example.HelloWorld())
}
In the above example, the import statement is used to import the example package, which is defined in a file named example.go. The file example.go contains the code for the HelloWorld function, which can be used in the main function of the current file.
Here is an example of what the example.go file might look like:
package example
func HelloWorld() string {
return "Hello, World!"
}
This file defines a function named HelloWorld that simply returns the string "Hello, World!".
