go拾遗(2)-函数返回数组、多个值、不显示指定返回

1、返回数组

package main

import "fmt"

func sumAdd(x ,y int) []int {
	var result [] int
	result=make([] int,0,6)
	for i:=0;i<5;i++{
		result=append(result,i+x +y)
	}
	return result
}

func main() {
	fmt.Println(sumAdd(1, 2))
}

2、返回多个值

package main

import "fmt"

func sumAdd(x ,y int) ([]int,int){
	var result [] int
	var sum int
	result=make([] int,0,6)
	for i:=0;i<5;i++{
		result=append(result,i+x +y)
		sum+=i+x +y
	}
	return result,sum
}

func main() {
	fmt.Println(sumAdd(1, 2))
}

	result=make([] int,0,6)
	for i:=0;i<5;i++{
		result=append(result,i+x +y)
