Chapter 4: Problem 6

The trailing else in an if/else if statement has a similar purpose as the __________ section of a switch statement.

Short Answer

Expert verified
Answer: The "default" section.

Step by step solution

01

Identifying the purpose of the trailing else and switch statement

The trailing else in an if/else if statement refers to the final 'else' block, which executes when none of the previous conditions (if and else if) are true. In a switch statement, a specific section also executes when no case matches the expression value.
02

Finding the corresponding section in a switch statement

In a switch statement, the 'default' section executes when no case matches the expression value. This serves a similar purpose as the trailing else in an if/else if statement.
03

Completing the exercise

Based on our understanding, we can now fill in the blank with the correct term: The trailing else in an if/else if statement has a similar purpose as the "default" section of a switch statement.

Write an if/else statement that assigns 0 to x when y is equal to 10. Otherwise it should assign 1 to x.

Write one or more \(\mathrm{C}++\) statements that assign the correct value to discount, using the logic described here: Assign .20 to discount if dept equals 5 and price is \(\$ 100\) or more. Assign .15 to discount if dept is anything else and price is \(\$ 100\) or more. Assign .10 to discount if dept equals 5 and price is less than \(\$ 100\). Assign .05 to discount if dept is anything else and price is less than \(\$ 100\).

An expression using the greater-than, less-than, greater-than-or-equal-to, less-than-orequal-to, equal, or not-equal operator is called a(n) __________ expression.

Sometimes either a switch statement or an if/else if statement can be used to implement logic that requires branching to different blocks of program code. But the two are not interchangeable. A) Under what circumstances would an if/else if statement be a more appropriate choice than a switch statement? B) Under what circumstances would a switch statement be a more appropriate choice than an if/else if statement? C) Under what circumstances would a set of nested if / else statements be more appropriate than either of the other two structures? Try to come up with at least one example case for each of the three, where it is the best way to implement the desired branching logic.

In an if/else statement, the if part executes its statement(s) if the expression is __________, and the else part executes its statement(s) if the expression is __________.
