Can you explain what this C++ code doing and give a detailed explanation of why the code does what it does?

What is the output of the following code? (You may assume that the file has all of the necessary #includes, etc).

1 double y = sqrt(2); 2 int n = 11 / 2; 3 4 bool b1 = (y*y-1==1); //false 5 bool b2 = (n=5.5); //true 6 bool b3 = b2+b1; //true 7 8 if (!b1 && (b2 || b3)) { 9 cout << "\"YEAH!\"" << fixed << setprecision(4);

10 cout << static_cast(b1) + static_cast(b2) + static_cast(b3); 11 cout << b3; 12 cout << " "; 13 } 14 else { 15 cout << "\"NAH!\"" <(b1) + static_cast(b2) + static_cast(b3); 17 cout << b3; 18 cout << " "; 19 }
