Analyze a 250-line C program to identify errors in logic, function calls, stack implementation, and typecasting. Fix the errors and discuss solutions to avoid stack overflow/underflow without explicit checks. Explain memory allocation, linked lists vs arrays, and memory management concepts like paging.

Context & Summary

Live coding round where the candidate analyzed a 250-line C program to identify errors. The program involved converting a Binary Tree into a Doubly Linked List in spiral fashion. Errors included incorrect function calls, lack of stack overflow/underflow checks, and typecasting issues. The candidate was then asked to fix the code and discuss memory allocation, linked lists vs arrays, and memory management concepts like paging.
