Question

(3 2) What is the result of this expression? Can it be short-circuited? 1 > 2 || 5 > 3 && 3 > 1 Which operation, || or &&, is evaluated first? In an if statement, how will the code inside of the parenthesis always be evaluated? i f (5) Is this if statement true or false? I f (0) Is this if statement true or false? if(x - 5) Is this an error, and if so is it a semantic error or a syntax error? Use the following code to answer the next few questions. Suppose the user types 85. What will the output of the code be? Suppose the user types 65. What will the output of the code be?

Explanation / Answer

45. (3 < 5) || (2 < 1). What is the result of this expression? Can it be short-circuited? The result of this expression is True. And yes, it can be short-circuited. If the first condition evaluates to true, the remaining conditions need not be evaluated. In this case, the first expression true, and the other half need not be evaluated.

46. (3 > 5) || (3 < 1). What is the result of this expression? Can it be short-circuited? The result of this expression is False. And yes, it can be short-circuited. If the first condition evaluates to true, the remaining conditions need not be evaluated. In this case, the first expression is false, and the second expression should also be evaluated.

47. (3 > 2) && (1 < 4). What is the result of this expression? Can it be short-circuited? The result of this expression is True. And yes, it can be short-circuited. If the first condition evaluates to false, the remaining conditions need not be evaluated. In this case, the first expression is True, and the second expression should also be evaluated.

48. (4 > 2) && (3 > 2). What is the result of this expression? Can it be short-circuited? The result of this expression is True. And yes, it can be short-circuited. If the first condition evaluates to false, the remaining conditions need not be evaluated. In this case, the first expression True, and the second expression should also be evaluated.
