如何在使用fstream

Question

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 !!";

当我输入数据时，我将在我提供的快照中显示，当我输入数据时没有任何空格一切顺利但是当我输入带空格的数据时我不能填写某些数据由于某种原因因为我不是初学者，所以我不知道。你能否告诉我确切的更新地点和更新内容。

你可能已经在图片中注意到我在i7和4790k之间放了一个空格，我无法填写输入处理器名称的信息，命令窗口将我直接转到下一行。
