go 结构体的实例化方式

package main

import "fmt"

// 定义老帅结构体,将老师中的各个属性统一放入结构体中管理:
type Teacher struct {
	//变量名字大写外界可以访问这个属性
	Name   string
	Age    int
	School string
}

func structAssignment1(){
	//创建老师结构体的实例、对象、变量:
	var t Teacher = Teacher{}
	fmt.Println(t)
	t.Name ="赵册珊" 
	t.Age = 31
	t.School="黑龙江大学"
	fmt.Println("t",t)
	var t1 Teacher = Teacher{"赵册5",31,"黑龙江大学"}
	fmt.Println("t1",t1)
}
	
func structAssignment2(){
	//创建老师结构体的实何、对象、变景;
	var t1 Teacher // 类似 var a int
	fmt.Println(t1)//在未赋值时默认值:{ 0 }
	t1.Name = "马主兵"
	t1.Age = 45
	t1.School ="清华大学"
	fmt.Println(t1)
	fmt.Println(t1.Age + 10)
}

func structAssignment3(){
	//创建老师结构体的实例、对象、变量:
	var t *Teacher = new(Teacher)
	//t是指针，t其实指间的就是地址，应该给这个地址的指向的对象的字段威值
	(*t).Name = "马士兵"
	(*t).Age = 45 //*的作用;根据地址取值
	//为了符合程产员的编程习惯。go挺供了简化的赋伯方式:
	t.School = "清华大学" //go编译器底层对t.School转化（*t).School = "清华大学"
	fmt.Println(*t)
}

func structAssignment4(){
	//创建老师结构体的实例、对象、变量:
	var t1 *Teacher = &Teacher{"马士:兵",46,"洁华大学"}
	fmt.Println(*t1)

	var t *Teacher = &Teacher{}
	(*t).Name = "写士兵"
	(*t).Age = 45
	t.School ="活华大学"
	fmt.Println(*t)
}

func main() {
	//structAssignment1()
	//structAssignment2()
	structAssignment3()
	//structAssignment4()
}
