Final answer:
The statement is False. Parentheses and braces are used to clarify the scope of control structures in programming, especially to avoid the confusion that can be caused by a dangling-else.
Step-by-step explanation:
The statement, True or False: Parentheses () would not be used to clarify a dangling-else, is False. In many programming languages, parentheses and braces (curly brackets) can both be used to clarify the scope of control structures, such as if and else statements.
The term 'dangling-else' refers to a situation where it is unclear to which if statement an else belongs. Programmers use parentheses and braces to structure the code in a way that clearly associates each else with its intended if statement.
In computer science, parentheses () are often used to clarify the grouping of expressions in programming languages. However, they are not used to clarify a dangling-else statement.
A dangling-else is a common source of confusion in programming languages like C, C++, and Java. It occurs when there is an if-else statement without explicit curly braces {} and is ambiguous as to which if statement the else clause belongs to.
For example, consider the following code:
if (x > 0) if (y > 0) System.out.println("x and y are both positive"); else System.out.println("x is positive but y is not");
In this case, the else clause is actually associated with the second if statement, not the first one. Using parentheses will not clarify this issue.
