Consider carefully the program fragment below:

bool p; ... if (p == true) cout << "p is true "; else

cout << "p is false ";

Which of the following are valid rewrites of the above? (More than one may be valid)

A. bool p; ... p? (cout << "p is true ") : (cout << "p is false ");

B. bool p; ... cout << "p is " << p << endl;

C. bool p; ... cout << "p is " << (p? "true" : "false") << endl;

D. bool p; ... if (p) cout << "p is true "; else cout << "p is false ";
