[Programming] Question 13: Demonstrate division by powers of 2 using right shift operator in C?

Learn how to efficiently divide integers by powers of 2 using the right shift operator (>>) in C. This guide explains how shifting the bits of a number to the right effectively performs division by powers of 2, offering a faster alternative to traditional division operations. The tutorial includes clear examples, step-by-step explanations, and sample code to help you understand and apply this technique in your C programs.

#include <stdio.h>

int main() {
	int num = 32;

	printf("Original number: %d\n", num);

	num = num >> 2; // Divide by 2^2 = 4

	printf("After division by 4: %d\n", num);

	return 0;
}

Inside the main() function:

- An integer variable num is initialized with the value 32.

- The original value of num is printed to the console.

- The num variable is right shifted by 2 bits using the `>>` operator, effectively dividing it by 4 (2^2).

- The result after division is printed to the console.
