qt - Qbytearray byte to int and storing it as string value -

i want convert byte data stored in qbytearray string value. string value using displaying in ui window..

 qbytearray array;     array.append( 0x02 );     array.append( 0xc1);     qdebug()<<( uint )array[0]<<"  "<<( uint )array[1];       uint = 0x00000000;     |= array[1];     qdebug()<<i;         uint j = 0x00000000 | ( array[0] << 8 );     qdebug()<<j;     |= j;      bool b = false;     qstring str = qstring::number( );     qdebug()<<str; 

but str prints "4294967233"...this code works of bytes 0x1, 0x45 , of other..but code not working bytes of data string..please me , write code , post here..thanks

all values equal or bigger 0x80 interprets in sample negative values, need cast unsigned type before bitwise operations.

qbytearray array; array.append( 0x02 ); array.append( 0xc1);  unsigned int value = 0; (int = 0; < array.size(); i++)     value = (value << 8) | static_cast<unsigned char>(array[i]);  qstring str = qstring::number(value); qdebug() << value << str;
