C++文件操作-文本文件读写+二进制文件读写

本文需求来自于留学生作业

#include <iostream>
#include <string>
#include <fstream>
#include <list>
using namespace std;

const int FIRST_NAME_LEN = 10;
const int SECOND_NAME_LEN = 10;
const int SOCIAL_SECURITY_LEN = 9;
const int DEP_ID_LEN = 9;

struct Record
{
	char m_firstName[FIRST_NAME_LEN] ;
	char m_secondName[SECOND_NAME_LEN] ;
	char m_socialSecurity[SOCIAL_SECURITY_LEN] ;
	char m_departmentID[DEP_ID_LEN] ;
	int m_years;
	int m_salary;
	int m_averageSalary;
	int m_averageYears;

	Record(void);

	friend istream& operator>>(istream& in, Record& record);
	friend ostream& operator<<(ostream& out, const Record& record);
	
	ofstream& Record::WriteToBinaryFile(ofstream& out) const;
	ifstream& Record::ReadFromBinaryFile(ifstream& fin);

	void WriteToOstream(ostream& os) const;

};

//在这里实现你的代码

///////////////////////////////////////////////

int main(int arcg, char** argv)
{
	list<Record> listEmployee;

	cout<<"ReadTextEmployee from employee.in"<<endl;
	if (!ReadTextEmployee("employee.in", listEmployee))
	{
		return -1;
	}
	PrintAllEmployee(listEmployee);

	cout<<"WriteEmployeeToBinaryFile to employee.binary\n"<<endl;
	WriteEmployeeToBinaryFile(listEmployee, "employee.binary");

	listEmployee.clear();

	cout<<"ReadBinaryEmployee from employee.binary"<<endl;
	ReadBinaryEmployee("employee.binary", listEmployee);
	PrintAllEmployee(listEmployee);

	CalculateAverage(listEmployee);
	PrintAllEmployeeWithAverage(listEmployee);
	WriteEmployeeToTextFile(listEmployee, "employee.out");

	return 0;
}

输出如下：
