[数据结构与算法]【C++】递增运算符重载

#include<iostream>
using namespace std;
#include <string.h>
class Integer {
	friend ostream& operator<<(ostream& cout, Integer inter);
public:
	Integer() {
		m_Num = 0;
	}
	//重载前置++运算符
	Integer& operator++() {
		m_Num++;
		return *this;//返回自身
	}
	//重载后置++运算符,返回值
	Integer operator++(int) {//int占位参数
		Integer temp = *this;
		m_Num++;
		return temp;
	}

private:
	int m_Num;
};
//重载左移运算符
ostream& operator<<(ostream& cout, Integer inter) {
	cout << inter.m_Num;
	return cout;
}
void test01() {
	Integer inter;
	/*cout << inter << endl;*/
	cout << ++inter << endl;
}
void test02() {
	Integer inter;
	cout << inter++ << endl;
	cout << inter << endl;
}
int main() {

	//test01();
	test02();

	system("pause");

	return 0;
