Exam Format 110 Total Points 60 Points Writing Programs 30 Points Tracing Algorithms and determining results 20 Points Short Answer Similar to quizzes and programming assignments

Example Programming Problem Write a function named getBigger that takes an integer parameter, prompts the user for a number, and then returns the higher of the two numbers.

Example Tracing Problem What will the EXACT output of the following program be? int foo = 9; string str = "Hey!"; float foo2 = 5.7; while (foo2 < foo) { if (foo2 > 3.14) { cout << str << “ bigger than PI!” << endl; foo -= 2; } else cout << foo << “loser” << endl;

Example Short Answer Why do we need function prototypes before the main function?
