Golang 中递归匿名函数
原文:https://www . geesforgeks . org/recursive-anonymous-function-in-golang/
递归是函数隐式或显式调用自身的过程，相应的函数称为递归函数。Go 语言支持名为 匿名功能 的特殊功能。这是一个不包含任何名称的函数。它用于创建内联函数。递归函数也可以声明&定义为匿名。递归匿名函数也称为递归函数字面量。
语法:
func(parameter-list)(return-type){
// code..
// call same function
// within the function
// for recursion
// Use return statement only
// if return-type are given.
return
}()
示例:
// Golang program to show
// how to create an recursive
// Anonymous function
package main
import "fmt"
func main() {
// Anonymous function
var recursiveAnonymous func()
recursiveAnonymous = func() {
// Printing message to show the
// function call and iteration.
fmt.Println("Anonymous functions could be recursive.")
// Calling same function
// recursively
recursiveAnonymous()
}
// Main calling of
// the function
recursiveAnonymous()
}
输出:
Anonymous functions could be recursive.
Anonymous functions could be recursive.
Anonymous functions could be recursive.
Anonymous functions could be recursive.

.
Infinite times function calls.
例 2:
// Golang program to show
// how to create an recursive
// Anonymous function
package main
import (
"fmt"
)
func main() {
// Anonymous function
var recursiveAnonymous func(int)
// Passing arguments
// to Anonymous function
recursiveAnonymous = func(variable int) {
// Checking condition
// to return
if variable == -1 {
fmt.Println("Welcome to Geeks for Geeks!")
return
} else {
fmt.Println(variable)
// Calling same
// function recursively
recursiveAnonymous(variable - 1)
}
}
// Main calling
// of the function
recursiveAnonymous(10)
}
输出:
