Final answer:
Using recursive functions in a program can result in using more code and more memory. However, they can also lead to shorter and more concise code and can solve complex problems.
Step-by-step explanation:
Using recursive functions in a program can have the effect of using more code and more memory.
A recursive function is a function that calls itself within its own definition. Each time the function calls itself, it creates a new instance of the function and adds it to the call stack, which can consume more memory.
However, recursive functions can also result in shorter and more concise code in some cases, as they can solve complex problems by breaking them down into smaller, recurring subproblems.
