Can you explain what dynamic scoping is?
Dynamic scoping is a method of variable scope resolution where the variable's value is determined by the call stack at runtime.
How does it differ from static scoping?
In static scoping, the variable's value is determined by the structure of the code at compile time, while dynamic scoping resolves it at runtime based on the calling context.
Can you give me an example of dynamic scoping in a programming language?
Sure! In languages like Perl, if a variable is defined in a function, it can be accessed by other functions that are called from within it, even if those functions are defined elsewhere.
What are the advantages and disadvantages of dynamic scoping?
Advantages include flexibility and ease of use in certain scenarios, while disadvantages involve potential confusion and difficulty in tracking variable values.
