Final Answer:
A dangling else logical error can be avoided through the use of brackets and indentation with all nested if/else.
When dealing with nested if/else constructs, without brackets, it becomes ambiguous which else clause corresponds to a particular if statement. In programming languages where indentation is not mandatory for syntax but considered good practice (like Python), correct indentation becomes crucial. Therefore, the correct answer is option 1) Brackets 2) Indentation
Step-by-step explanation:
Brackets, also known as curly braces `{}`, are used to define a block of code, ensuring that the scope of the if/else constructs is clearly defined. This helps in associating the correct else clause with its corresponding if statement. Without brackets, the compiler may misinterpret the code structure, leading to a dangling else error.
In addition to brackets, **indentation** plays a crucial role in enhancing code readability and avoiding logical errors. Proper indentation visually represents the hierarchical structure of nested if/else constructs. By aligning the code correctly, programmers can easily identify the scope of each block, making it less prone to errors. Indentation is a good practice that aids in maintaining a clear and organized code structure, reducing the chances of introducing bugs or logical errors.
In summary, the combination of brackets and indentation provides a robust solution for handling nested if/else constructs and preventing dangling else errors. Brackets define the boundaries of code blocks, and indentation visually represents the hierarchy, ensuring that the code is both syntactically correct and easy to understand. This coding practice contributes to the overall maintainability and reliability of software systems.
