Given a 32-bit word W containing a 6-bit field in bit positions 12 to 17 (bit position 0 is the least significant bit), write the assignment statements to store the int value X into that field without altering the other bits in W. PLEASE EXPLAIN WHY THEY ARE MASKING W WITH THAT HEXADECIMAL where was that info gotten and HOW THE X VALUE WAS FOUND. PLEASE EXPLAIN IN DETAIL THANKS. LANGUAGE:C

Answer:

W &= 0xFFFC0FFF; // clear the field within W

X &= 0x3F; // make sure X is valid

W |= (X << 12);
