Demonstrate bitset

<source lang="cpp">

  1. include <iostream>
  2. include <bitset>

using namespace std; int main() {

 bitset<16> bitsetObject(32);
 cout << "Bits:";
 cout << bitsetObject; 
 cout << endl;
 bitsetObject[0] = 1;
 bitsetObject[2] = 0;
 bitsetObject[10] = 1;
 bitsetObject[12] = 1;
 cout << "Bits:";
 cout << bitsetObject;
 cout << endl;
 
 bitsetObject <<= 2;   // rotate bits
 cout << "Bits rotate: ";
 cout << bitsetObject;
 cout << endl;
 
 bitsetObject.flip(); // flip bits
 cout << "After flipping bits:    ";
 cout << bitsetObject;
 cout << endl;
 if(bitsetObject.any()) 
    cout << "bitsetObject has at least 1 bit set.\n";
 
 cout << "bitsetObject has " << bitsetObject.count();
 cout << " bits set.\n";
 // test bits different three ways
 if(bitsetObject[0] == 1)
   cout << "bit 0 is on\n";
 if(bitsetObject.test(1))
   cout << "bit 1 is on\n";
 cout << "Add 11 to bit 0: " << bitsetObject[0] + 11 << endl;   // can add bits to integers
 return 0;

}
