C++文件读写

想了想。。计算机里面的文件。。再怎么变也还是机器码。。0101嘛。。二进制读写文件。。稳

试了试。。png mp4格式都可以。

void playPNG()
{
  ifstream in("1.png", ios_base::binary | ios_base::in);
  if (in.is_open())
  {

    in.seekg(0, ios::end);
    int pSize = in.tellg();
    in.seekg(0, ios::beg);
    char*imgbf = new char[pSize];
    in.read((char*)imgbf, pSize);
    in.close();
    ofstream out("2.png", ios_base::binary|ios_base::out);
    if (out.is_open())
    {
      out.write((char*)imgbf, pSize);
      out.close();
    }
  }
}
