What is typically an indicator of potential stack overflow in recursive functions?

• A. Excessive memory allocation
• B. Improper termination conditions
• C. Calling functions within a loop
• D. Not using return statements

Answer: (B)

In recursive functions, improper termination conditions are a critical factor that can lead to potential stack overflow. A recursive function should have a clear base case that allows the recursion to terminate; this means that under certain conditions, the function should stop calling itself. If these conditions are not set correctly, the function can continue to call itself indefinitely, leading to an excessive number of function calls that exceed the call stack limit. When the recursion infinitely continues due to improper termination conditions, the program keeps pushing new function calls onto the call stack without ever returning, which eventually exhausts the stack space allocated by the system. This results in a stack overflow error. Hence, it is crucial to define and implement effective termination conditions in order to prevent this situation from arising in recursive functions.
