以换行增量返回二进制结果

Question

我正在尝试将十六进制转换为二进制，并接收具有以下功能的文本文件：

3c011001 34300000 8e080000 20090003 11200004

但它在同一行输出二进制文件：

0011 1100 0000 0001 0001 0000 0000 0001 0011 0100 0011 0000 0000 0000 0000 0000 1000 1110 0000 1000 0000 0000 0000 0000 0010 0000

我想这样退货：

0011 1100 0000 0001 0001 0000 0000 0001

0011 0100 0011 0000 0000 0000 0000 0000

等。

string hex (string sHex)
{
   string sReturn = "";
   for (int i = 0; i < sHex.length (); ++i)
   {
    switch (sHex [i])
    {
        case '0': sReturn.append ("0000 "); break;
        case '1': sReturn.append ("0001 "); break;
        case '2': sReturn.append ("0010 "); break;
        case '3': sReturn.append ("0011 "); break;
        case '4': sReturn.append ("0100 "); break;
        case '5': sReturn.append ("0101 "); break;
        case '6': sReturn.append ("0110 "); break;
        case '7': sReturn.append ("0111 "); break;
        case '8': sReturn.append ("1000 "); break;
        case '9': sReturn.append ("1001 "); break;
        case 'a': sReturn.append ("1010 "); break;
        case 'b': sReturn.append ("1011 "); break;
        case 'c': sReturn.append ("1100 "); break;
        case 'd': sReturn.append ("1101 "); break;
        case 'e': sReturn.append ("1110 "); break;
        case 'f': sReturn.append ("1111 "); break;
    }
  }
  return sReturn;
  }

int main() {
  ifstream file;
  file.open("MachineCode.txt");
    if (!file.is_open())
  {
    cout << "ERROR";
  } else {
    stringstream strStream;
    strStream << file.rdbuf();
    string contents = strStream.str();
    cout << hex(contents) << endl;

}

return 0;

}

我添加了一个新案例，它检测输入中何时有新行以将新行添加到输出中。

case '\n': sReturn.append ("\n"); break;
