Write a program in cpp language to reverse the bits of a user entered number and print the decimal format obtained by reversing the bits of that number.

Ans:> 

Code:

#include <iostream>

using namespace std;

unsigned int reverseBits(unsigned int n){
    unsigned int res = 0;
    while(n > 0){
        res <<= 1;
        if(n & 1 == 1){
            res ^= 1;
        }
        n >>= 1;
    }
    return res;
}
int main()
{
    unsigned int n;
    cout<<" Enter the number: ";
    cin>>n;
    cout<<"Reverse BIts number is: "<<reverseBits(n);

    return 0;
}
