C ++从txt文件中读取并保存所有内容＆＃34; |＆＃34;在一个缓冲区

Question

嗯，很难准确地解释我想要的东西，我只是举个例子。

{accbeingused0or1}|{accName}|{accPassword}|{gameName}|{gamePassword}

所以它看起来像这样：

0|account123|password123|gamename123|password123

Answer 1

你走了：

template< char Ch >
std::istream& Char( std::istream& is )
{
    if( (is >> std::ws).get() != Ch )
        is.setstate( std::ios::failbit );

    return is;
}

struct Data
{
    int acc_used;
    std::string accountName;
    std::string accountPassword;
    std::string gameName;
    std::string gamePassword;
};

std::istream& operator>>( std::istream& is, Data& d )
{
    is >> d.acc_used >> Char<'|'> >> std::ws;
    std::getline( is, d.accountName, '|' );    
    std::getline( is, d.accountPassword, '|' ); 
    std::getline( is, d.gameName, '|' ); 
    is >> d.gamePassword;
    return is;
}
