how to trigger carriage return after 8 characters

[jerry HQ]

I would like to have carriage return after 8 characters so it would look like

11111111
11111111
00000000
00000000

instead of

1111111111111111000000000000000000000000000000001111111111111111


I am attempting to make a bit board for chess.

Thanks

  #include <iostream>
#include <iostream>
#include <string>
#include <math.h>  
#include <iomanip> 

int main(){

const unsigned long long board = 18446462598732906495LLU;
std::string binary = std::bitset<64>(board).to_string();
std::cout << std::setw(8);
std::cout.width(8);
std::cout<<binary<<"\n";


return 0;
}//end main

#include <iostream>
#include <string>
#include <bitset>

int main()
{
   const unsigned short trg_return = 8;

   const unsigned long long board = 18446462598732906495LLU;

   std::string binary = std::bitset<64>(board).to_string();

   for (size_t loop = 0; loop < binary.size(); loop++)
   {
      std::cout << binary[loop] << ' ';

      if (0 == ((loop + 1) % trg_return))
      {
         std::cout << '\n';
      }
   }
}

1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1

Thank you for the prompt response!

I am attempting to make a bit board for chess.

A chess game with one type of piece?

A lot of work IMO, bit math decode and encode and manipulation, just to save a few bytes.
