关于结构体的文件存储及读取的问题
关于以下结构体中数据的二进制文件的存储与读取：
typedef struct point
{
int x;
CPoint begin;
CPoint end;
}point;
typedef std::vector<point> ar_point;
ar_point m_point;

我写了一个存储的函数（存储产生的文件是二进制的），有没有人能够给出一个读取的函数？或者是相关的源代码的下载链接？
（废话不给分）
void CXView::Save()
{
ofstream ofs("SaveFile.dat",ios::binary);
INT i = 0;
for(std::vector<point_x_y>::iterator it = m_point.begin();it != m_point.end();it++)
{
ofs.write((char*)&m_point[i],sizeof(m_point));
i++;
}
ofs.close();
}

[解决办法]

C/C++ code

#include <iostream>#include <fstream>#include <vector>using namespace std;typedef struct point{    int x;    CPoint begin;    CPoint end;}point;class CXView{public:    typedef std::vector<point> ar_point;    ar_point m_point;    void Init();    void Draw();    void Save();    void Load();};void CXView::Init(){    point pt;    pt.x = 100;    pt.begin = CPoint( 1, 2 );    pt.end = CPoint( 3, 4 );    m_point.push_back( pt );    pt.x = 200;    pt.begin = CPoint( 11, 22 );    pt.end = CPoint( 33, 44 );    m_point.push_back( pt );}void CXView::Draw(){    for( vector< point >::iterator it = m_point.begin(); it != m_point.end(); ++it )    {        cout << it->x << " " << it->begin.x << " " << it->begin.y            << " " << it->end.x << " " << it->end.y << endl;    }}void CXView::Save(){    ofstream ofs("SaveFile.dat",ios::binary);    int len = m_point.size();    ofs.write( (char*)&len, sizeof(len) );    INT i = 0;    for(std::vector<point>::iterator it = m_point.begin();it != m_point.end();it++)    {        ofs.write((char*)&m_point[i],sizeof(point));        i++;    }    ofs.close();}void CXView::Load(){    m_point.clear();    ifstream ifs("SaveFile.dat",ios::binary);    int len;    ifs.read( (char*)&len, sizeof( len ) );    for( int i1 = 0; i1 < len; ++i1 )    {        point pt;        ifs.read( (char*)&pt, sizeof(point) );        m_point.push_back( pt );    }    ifs.close();}int main(){    CXView view;    view.Init();    view.Save();    view.Draw();    cout << "--------------------华丽丽的分隔线--------------------" << endl;    view.Load();    view.Draw();    return 0;}
