如何更改程序以在使用fstream时输入带空格的数据

void主板：：添加（）
{
字符x；
int X；
fstream InFileMB（“Motherboard_List.txt”，ios:：in | ios:：out | ios:：app）；
如果（！emb）
{
cerr制造商名称；
cout>MB_芯片；
cout>MB_名称；
cout MB_特性1；
cout MB_特征2；
cout MB_特征3；
cout MB_价格；
系统（“cls”）；
cout的语法是什么？比如std:：getline（MB_芯片）这是我应该写的吗？如果是这样，我还需要对那些cout语句进行更改吗？你不需要更改输出。上面的注释是指向引用的链接，它将显示必要的语法。它似乎对我不起作用。
void Motherboards::add()
{
char x;
int X;
fstream InFileMB("Motherboard_List.txt", ios::in | ios::out | ios::app);
if (!InFileMB)
{
    cerr << "Error: Opening File Failed !!";
}
else
