EX: write a C program to perform bitwise left shift operation. How to write a C program to perform bitwise left shift operation of intiger. C program to perform bitwise left shift operation of intiger.

Input from user:

Enter the number:15

Enter how many numbers you wan't to left shift:1

Expected Output:

Output after performing left shift operation is: 30

  Logic to perform left shift operation of two intiger's:

 First you need to know how left shift operator works.

•  It  takes two numbers and left shift the bits of the first operand, the second  operand decides the number of places to shift.

1. We take two intiger numbers i.e, no=15 and s=1.
Where no shows the number which you wan't to left shift and s shows the how many bits you want to left shift.

 2. Binary representation of no<<s is-

      no    = 00001111

------------------------------------ 

 no<<s   = 000011110 =30(in decimal)

3. After performing left shift operation 8 bit binary representation is 00001 1110 which is 30 in decimal.

4. So output of the program is  30.

  C program using bitwise left shift :

#include<stdio.h>

void main()

{

int no,s;

printf("Enter the number\n");

scanf("%d",&no);

printf("Enter how many bits you wan't to left shift\n");

scanf("%d",&s);

printf("Output after performing left-shift operation is:%d",no<<s);

}

Above program shows the following output:
