Write a routine to perform a bitwise AND, OR, and XOR on two integers, a bitwise NOT on the first integer, a left shift, right shift, right arithmetic shift, left rotate, and right rotate. All shifts and rotates should be done on the first integer with a shift/rotate amount of the second integer. If any operation is not available in your language, note it.
#include <iostream> void bitwise(int a, int b) { std::cout << "a and b: " << (a & b) << '\n'; // Note: parentheses are needed because & has lower precedence than << std::cout << "a or b: " << (a | b) << '\n'; std::cout << "a xor b: " << (a ^ b) << '\n'; std::cout << "not a: " << ~a << '\n'; std::cout << "a shl b: " << (a << b) << '\n'; // Note: "<<" is used both for output and for left shift std::cout << "a shr b: " << (a >> b) << '\n'; // typically arithmetic right shift, but not guaranteed unsigned int c = a; std::cout << "c sra b: " << (c >> b) << '\n'; // logical right shift (guaranteed) // there are no rotation operators in C++ }
