一、Demo 之常用变量类型以及函数

package main

import (
	"fmt"
	"time"
)

var testNumber = 20

func main() {
	//var  _age int = 123
	var _age = 24
	datetime := time.Now()
	fmt.Println("Hello, Go! I'm ",_age,"year's old","当前时间",datetime)
	fmt.Println("当前时间",datetime)
	max(12,11)
}

func max(num1,num2 int) {
	var result = num1 + num2 + testNumber
	//getString :=[...]string{}
	var getString[12] string
	for  i := 0 ; i < 10 ; i++{
		result += i
		fmt.Println(i,"测试一下循环输出")
		getString[i] = fmt.Sprintln(i,"测试一下字符串数组的赋值")
	}
	fmt.Println(result,"这个是字符串数组:",getString)
	fmt.Println(fmt.Sprintln(ReturnResultAndGetString(20,21)),"测试一下函数的返回值")
	fmt.Println("测试一下函数的返回值",fmt.Sprintln(ReturnResultAndGetString(20,21)),"")
	fmt.Println("测试返回值不同的使用方式",fmt.Sprintln(ReturnResult(20,21)),"")
}

func ReturnResultAndGetString(num1,num2 int) (result int,getString[12] string){
	 result = num1 + num2 + testNumber
	//getString :=[...]string{}
	for  i := 0 ; i < 10 ; i++{
		result += i
		fmt.Println(i,"测试一下循环输出")
		getString[i] = fmt.Sprintln(i,"测试一下字符串数组的赋值")
	}
	fmt.Println(result,"这个是字符串数组:",getString)


	return
}

func ReturnResult(num1, num2 int) (int, [12]string) {
   var result = num1 + num2 + testNumber
	//getString :=[...]string{}
	var getString[12] string
	for  i := 0 ; i < 10 ; i++{
		result += i
		fmt.Println(i,"测试一下循环输出")
		getString[i] = fmt.Sprintln(i,"测试一下字符串数组的赋值")
	}
	fmt.Println(result,"这个是字符串数组:",getString)
	return result,getString
}
