练习LabVIEW第二十一题

this指针指向当前对象，且是已经创建的对象

使用this指针甚至可以让成员函数的参数和成员变量重名

图中高亮部分体现了成员变量与成员函数参数的关系

显然，this指针指向的变量与对象的成员变量相关联

this指针只在类的成员函数内部使用

演示代码如下：

#include <iostream>

using namespace std;

class student
{

private:
	string name;
	int age;
	float score;

public:
	student();
	student(string name, int age, float score);
	void print();
};

student::student()
{
	this->name = "";
	this->age = 0;
	this->score = 0.0;
}

student::student(string name, int age, float score)
{
	this->name = name;
	this->age = age;
	this->score = score;
}

void student::print()
{
	cout << "姓名：" << this->name << endl;
	cout << "年龄： " << this->age << endl;
	cout << "分数： " << this->score << endl;
}

int main()
{
	student stu("zzj", 19, 98);
	stu.print();
	return 0;
}
