The byte x is initialized to 0x14 (20 decimal or 00010100 binary):
byte x = 0x14; // 00010100 // clear least significant set bit // ____?____ // 00010000
Which one of following bitwise operations on x can clear the least significant set bit in x. After the bit is cleared x should be 0x10 (00010000). Note that the correct choice is a generic solution that works on any value, and on any size integer ( int, byte or short ).
