Description: A block is a section of code that can be executed as a unit. In the context of programming, a block can contain one or more instructions that are grouped together to perform a specific task. Blocks are fundamental in the structure of many programming languages, as they allow for logical and modular organization of code. For example, in languages like Python, a block of code is defined by indentation, while in others like C or Java, braces ({}) are used to delimit the start and end of the block. This organization not only improves code readability but also facilitates maintenance and reuse. Blocks can be used in various control structures, such as loops and conditionals, and are essential for creating functions and methods, where they encapsulate the logic that can be invoked in different parts of a program.
