C++ 基础将数据 以二进制的方式写入文件

// BinaryStorageData.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "iostream"

//-- 要想将结构体变量数据存储进文件中，结构体中不能有指针类型成员
struct CStudent 
{
	TCHAR szName[10];
	int iAge;
};
#define FILEPATH  _T("struct.bin")
int _tmain(int argc, _TCHAR* argv[])
{
	//-- 构建变量
	CStudent cStu[2];
	wcscpy_s(cStu[0].szName, _T("张三"));
	cStu[0].iAge = 100;

	wcscpy_s(cStu[1].szName, _T("li三"));
	cStu[1].iAge = 10;

	FILE *fp = nullptr;
	_tfopen_s(&fp, FILEPATH, _T("wb"));
	if (nullptr == fp)
	{
		std::cout << "打开文件失败" << std::endl;
	}
	else
	{
		fwrite(&cStu, sizeof(CStudent), 2, fp);
		fclose(fp);
	}
	getchar();

	_tfopen_s(&fp, FILEPATH, _T("rb"));
	if (fp != nullptr)
	{
		CStudent cStuTemp[2];
		fread(&cStuTemp, sizeof(CStudent), 2, fp);
		fclose(fp);
	}
	return 0;
