Exam 4: Control Structures I Selection

Every else must be paired with a(n) ____________________.

Suppose found = true and num = 6. The value of the expression (!found) || (num > 6) is ____________________.

The expression (x >= 0 && x <= 100) evaluates to false if either x < 0 or x >= 100.

What is the output of the following code? if (6 > 8) { $\quad$ cout << " ** " << endl ; $\quad$ cout << "****" << endl; } else if (9 == 4) $\quad$ cout << "***" << endl; else $\quad$ cout << "*" << endl;

What is the output of the following code fragment if the input value is 4? int num; Int alpha = 10; cin >> num; switch (num) { case 3: $\quad$ alpha++; $\quad$ break; case 4: case 6: $\quad$ alpha = alpha + 3; case 8: $\quad$ alpha = alpha + 4; $\quad$ break; default: $\quad$ alpha = alpha + 5; } cout << alpha << endl;

Putting a semicolon after the parentheses following the expression in an if statement (that is, before the statement) is a(n) ____________________ error.

What does <= mean?

The symbol > is a(n) ____________________ operator.

Which of the following operators has the lowest precedence?

What is the output of the following C++ code? int x = 35; int y = 45; int z; if (x > y) $\quad$ z = x + y; else $\quad$ z = y - x; cout << x << " " << y << " " << z << endl;
