Chapter 2, Problem 8E

Program Plan Intro

Method definition of rightrot(x,n):

/*function definition of right rot*/
unsignedint rightrot(unsignedint x,unsignedint n)
{

/*loop till the bit positions*/
while(n>0)
{
/*condition to rotate each bit by one position.*/
if(x&1)
{
 x =(x >>1)|~(~0U>>1);
}
else
{
 x =(x >>1);
}
 n--;
}

return x;
}

Program Plan-

• Initialize the header files and main() function.
• To define the function rightrot(x, n) to rotate x right by n bits.
• Finally prints the value of x..

Summary Introduction- The program displays the x value after rotating it right by n bits.

Program Description- The purpose of the program is todefine the function rightrot(x, n) to return x with the n bits rotated towards right.
