Go学习笔记-匿名函数

package main

import "fmt"

var (
	// 全局匿名函数
	res = func(m int, n int) int {
		return m + n
	}
)

func main() {

	// type 1
	a := func(b int, c int) int {
		return b + c
	}(1, 2)

	fmt.Println(a)

	// type 2
	d := func(e int, f int) int {
		return e * f
	}

	g := d(1, 2)

	fmt.Println(g)

	// type 3
	t := res(3, 4)
	fmt.Println(t)

}
