c++ - 我无法在我的 if 语句中识别 endl 字符\n

Question

我正在为游戏创建 ASCII 艺术，而我的 fstream 没有在我的 if 中接收到 '\n'(使用 char)从流中删除的语句。看起来很简单，但我现在对此感到困惑..有什么线索吗？

void pic_maker(ifstream &Pic_file, string P_Name, int x, int y, int t)
{
Pic_file.open(P_Name);
int margin = 0;
coordinate(x, y);
char pic_info;
Pic_File >> pic_info;

while (!Pic_File.eof())
{
    while (pic_info == '?')
    {
        Pic_File >> pic_info; //ADDS SPACES TO IMAGE BY REPLACING ?
        cout << " ";
    }
    if (pic_info == '0') //RETURNS TO NEW LINE
    {
        Pic_File >> pic_info;
        y++;
        coordinate(x, y);
    }
    if (pic_info == '\n') //MY PROBLEM! DOESN'T RECOGNIZE \n
    {
        Pic_File >> pic_info;
    }
    cout << pic_info;
    Pic_file >> pic_info;
}

Sleep(t);
}

AFAIR >> 运算符默认情况下会跳过换行符。如果你还想读取空格，那么你应该在读取字符之前添加 noskipws。

Pic_File >> std::noskipws;
