[Day 10] Operator 3: Bitwise Shift Operator

In this class, I learn the bitwise shift operator including '<<' and '>>'.

1. Right-shift operator (>>)
    - The right-shift operator (<<) moves the bits of an integer or enumeration type expression to the right.

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[]) {
    
    int A = 0b1000;
    
    A = A >> 2;
    
    printf('%x', A);    
    
    return 0;
}

The results showed 'A' as 0b0010 that which resulted in change of 2^(-2).

2. Left-shift operator (<<) 
    - The left-shift operator (<<) moves the bits to the left.

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[]) {
    
    int A = 0b0001;
    
    A = A << 2;
    
    printf('%x', A);    
    
    return 0;
}

The results showed 'A' as 0b0100 that which changed by the square of 2.
