写入.dat文件会导致写入随机的中文字符

Question

我有这个程序：

using namespace std;

class Motherboards
{
    char Board_Manufacturer_Name[50];
    char Socket_Type[50];
    char Chipset_Type[50];
    char Board_Name[50];
    char Feature1[500];
    char Feature2[500];
    char Feature3[500];
    float Price;

    public:
    void getdata();
    void displaydata();
};
void Motherboards::getdata()
{
    cout << " Enter Manufacturer Name :\n";
    cin.getline(Board_Manufacturer_Name, 50);
    cout << "\n Enter the Socket type :\n";
    cin.getline(Socket_Type, 50);
    cout << "\n Enter the Chipset Type :\n";
    cin.getline(Chipset_Type, 50);
    cout << "\n Enter the Board Name :\n";
    cin.getline(Board_Name, 50);
    cout << "\n Enter 3 main features for this Board :\n";
    cout << "\n1.) ";
    cin.getline(Feature1, 500);
    cout << "\n2.) ";
    cin.getline(Feature2, 500);
    cout << "\n3.) ";
    cin.getline(Feature3, 500);
    cout << "Price :\n";
    cin >> Price;
    cout << "\n";
}
void Motherboards::displaydata()
{
    cout << " Manufacturer : " << Board_Manufacturer_Name << endl;
    cout << " Socket : " << Socket_Type << endl;
    cout << " Chipset : " << Chipset_Type << endl;
    cout << " Board Name : " << Board_Name << endl;
    cout << " Features :\n" << "1.) " << Feature1 << endl
        << "2.) " << Feature2 << endl
        << "3.) " << Feature3 << endl;
    cout << " Price :\n" << Price;
    cout << "\n";
} 

int main()
{
    int x;
    system("cls");
    Motherboards M;
    fstream Infile;
    Infile.open("MotherboardList.dat", ios::in | ios::out | ios::app);
    if (!Infile)
    {
        cerr << "Error :";
    }
    cout << "Enter the details of the motherboard that you want to add :\n";
    M.getdata();
    Infile.write((char*)&M, sizeof(M));
    cout << "Do you wanna confirm ?";
    M.displaydata();
    cin >> x;
    cout << "Written :\n";
    Infile.read((char*)&M, sizeof(M));
    M.displaydata();
    Infile.close();

    return 0;
}

我得到了这个输出：

为什么我的数据是用一些随机语言（也许是中文？）编写的，我需要更改什么来实际正确地写入数据呢？

我希望文本文件是英文的。另外，我输入的每个数据后不应该有换行符吗？

Answer 1

您创建的文件不是有效的文本文件，而是二进制文件。 您正在以二进制表示形式将c ++结构的内部编写到文件中。

如果您希望文件是人类可读的，请在写入文件之前将结构序列化为字符串，使用JSON或XML。

如果您希望c程序理解它，请在阅读后反序列化。
