Question

in c programming language .

10.14 (Reversing the Order of an Integer's Bits) Write a program that reverses the order of the bite! in an unsigned int value. The program should input the value from the user and call function re verseBits to print the bits in reverse order. Print the value in bits both before and after the bits are reversed to confirm that the bits are reversed properly.

Answer 1

SOURCE CODE IN C:

#include <stdio.h>

//function to reverse the bits of a given integer

void reverseBits(unsigned int *x)

{

//declaring variables

int copy=*x, rev=0;

//finding the reverse

while(copy!=0)

{

rev=(rev*10)+(copy%10);

copy/=10;

}

//storing the reverse

*x=rev;

}

int main(void)

{

//testing the function

unsigned int x;

printf("Enter an integer: ");

scanf("%d",&x);

printf("\nInteger before reversing: %d\n",x);

reverseBits(&x);

printf("\nInteger after reversing: %d\n",x);

return 0;

}

OUTPUT:

Enter an integer: 456 Integer before reversing: 456 Integer after reversing: 654
