What is the difference between static and dynamic scoping in programming?
Static scoping, or lexical scoping, determines variable scope at compile time, while dynamic scoping determines it at runtime.
Can you give me an example of each?
Sure! In static scoping, a variable defined in a function is accessible only within that function and its nested functions. In dynamic scoping, a variable can be accessed by any function that is called after it is defined, regardless of where it is defined.
Which one is more commonly used in modern programming languages?
Most modern programming languages, like Java and Python, use static scoping because it makes code easier to understand and maintain.
Are there any languages that use dynamic scoping?
Yes, languages like Perl and some Lisp dialects use dynamic scoping, although it's less common in contemporary programming.
