Benchmark: Bitwise vs. Modulo for Even Number Check

This post benchmarks two methods for checking if a number is even in Pascal and C: modulo operation and bitwise operation. The bitwise approach (using the bitwise AND operator) proves significantly faster. A Pascal test iterating from 0 to MaxInt showed bitwise operations were nearly 15 times quicker than modulo. In C, while compiler optimization might translate modulo 2 to bitwise AND, the bitwise method still slightly outperformed modulo. This highlights the efficiency advantage of bitwise operations for even number checks in performance-critical scenarios.
