Curly Braces are used for which of the following purposes?

• A. Defining Variables
• B. Script Blocks
• C. Loop Control
• D. Array Declaration

Answer: (B)

Curly braces are primarily used in programming languages to define script blocks, including the bodies of functions, loops, and conditionals. When a block of code is enclosed in curly braces, it signifies that the statements within are part of a single unit of execution. This structure helps in organizing code, making it clearer which statements belong together, especially in languages like Java, C, C++, and JavaScript.

For instance, in a function definition or within an if-statement, the code that should execute when the function is called or when the condition is true is contained within curly braces. This usage is fundamental to controlling the flow of execution and is essential in defining the scope of variables and statements within that block.

In contrast, defining variables typically does not require curly braces, loop control structures may utilize parentheses along with or without braces depending on the language, and array declarations often employ square brackets or other specific syntax rather than curly braces.
