What are the shift operations in C language?
Problem
What is the simple program to show the left, right shifts, and complement of a number by using C language?
Solution
Left Shift
If the value of a variable is left-shifted one time, then its value gets doubled.
For example, a = 10, then a<<1 = 20
Right shift
If the value of a variable is right-shifted one time, then its value becomes half the original value.
For example, a = 10, then a>>1 = 5
Example
Following is the C program for the shift operations −
#include<stdio.h>
main (){
int a=9;
printf("Rightshift of a = %d
",a>>1);//4//
printf("Leftshift of a = %d
",a<<1);//18//
printf("Compliment of a = %d
",~a);//-[9+1]//
printf("Rightshift by 2 of a = %d
",a>>2);//2//
printf("Leftshift by 2 of a = %d
",a<<2);//36//
}Output
When the above program is executed, it produces the following result −
Rightshift of a = 4 Leftshift of a = 18 Compliment of a = -10 Rightshift by 2 of a = 2 Leftshift by 2 of a = 36
