How can i use tht in c++?

//double entry = pixelSize/8;
int entry = pixelSize/8;

//IntPtr realByteAddr = new IntPtr( System.Convert.ToInt32(data.Scan0.ToInt32() + 
//                      (j*data.Stride ) + i*entry ));
  byte* realByteAddr = ((byte*)data.Scan0) + (j*data.Stride) + i*entry;
  
//byte[] dataToCopy = new byte[] { index };
  byte dataToCopy = index;
  
//Marshal.Copy( dataToCopy, 0, realByteAddr, dataToCopy.Length );
  *realByteAddr = dataToCopy;
