问使用bits时的警告

 BYTE original = 0xF0F0;
     BYTE bMask = 0x0000;
BYTE wMask = 0xFFFF;
BYTE  newBits = 0xAAAA;

/*& operation with "0bit set 0" & "1bit give no change to original byte" */
cout<<"Original o: "<<bits(original)<<endl;
cout<<"NewBits: "<<bits(newBits)<<endl;
cout<<"BMask m: "<<bits(bMask)<<endl;
cout<<"WMask m: "<<bits(wMask)<<endl;
cout<<"o & m with BMask: "<<bits(original & bMask)<<endl;/*0 set original bit as 0 */
cout<<"o & m with WMak: "<<bits(original & wMask)<<endl;/*1 bit put no effect on image*/
cout<<"Result"<<bits(original & wMask | newBits)<<endl;
