Explanation of Bitwise C Operator with Examples

Bitwise operator:

• x=x<<2   means new value of x is shifted left by 2 positions
• y=y>>3   means new value of y is shifted right by 3 positions

Program of bitwise operator:

#include<stdio.h>

void main()

{

int x,y;

x=128;                             

y=32;

x=x>>1;

printf(" After right- shifting by 1, x=%d/n" ,x);

y=y<<2;

printf(" After left- shifting by 2, y=%d/n" ,y);

}             // End of main() //       

              

Output:

 /* Binary value of x before shifting :

1

0

Binary value of x after shifting right by 1 :

After right-shifting by 1, x=64                       // 64 is equivalent to 01000000 binary number //

/* Binary value of y before shifting :

After left-shifting by 2, y=128             // 128 is equivalent to 001000 binary number //
