A "Code Block" is a section of code that is grouped together, often used in programming to define a specific function or control structure. It typically consists of multiple lines of code that are executed as a single unit. Code blocks help organize code, making it easier to read and maintain. They are commonly found in programming languages like Python, Java, and C++. In many programming languages, code blocks are defined using specific syntax, such as indentation in Python or curly braces in Java and C++. This structure allows programmers to create loops, conditionals, and functions, enabling more complex and efficient coding practices. Code blocks are essential for structuring programs logically.
