Question

write a program to swap all odd bits with next even bits of integer. how do i get

Answer 1

Something like this?

#include<iostream>
#include<bitset>

using namespace std;

const size_t bit_num = 8;

int main ()
{
  bitset<bit_num> num(42); // for example

  cout << "Num: " << num << endl;
 
  for(size_t i = 0; i < bit_num; i += 2) {
      bitset<1> temp(num[i]);
      num[i]  = num[i + 1];
      num[i + 1] = temp[0];
  }
 
  cout << "Num: " << num << endl;
 
  return 0;
}
