WebIf you count shifting as a bitwise operator, this is easy. You already know how to do it by successive division by 2. x >> 1 is the same as x / 2 for any unsigned integer in C. If you need to make this faster, you can do a "divide and conquer"—shift, say, 4 bits at a time until you reach 0, then go back and look at the last 4 bits. birds park polgahawela contact numberWebThe bitwise-manipulation operators perform simultaneous bit manipulations and enable programs to process large quantities of binary information efficiently.
