using namespace std;  

int main()
try
{

   string myString = "Hello World"; // string object

   vector> us;           // string to binary array of each characater

   for (int i = 0; i < myString.size(); ++i)
   {
        // After convert string to binary, push back of the array
        us.push_back(bitset<8>(myString[i]));
   }

   string c;  // binary to string object

   for (int i = 0; i < us.size(); ++i)
    {
        // the function 'to_ulong' returns
        // integer value with the same bit representation as the bitset object.
        c += char(us[i].to_ulong());
    }

    cout << c;

}
catch (exception& e)
{
    cerr << "the error is : " << e.what() << '\n';
}

output : Hello World
