Debugging, Best Practices, and Interview Patterns

Identify and prevent null pointer dereferences, uninitialized pointers, and dangling pointers.

Apply defensive programming techniques, such as nulling pointers after deallocation.

Use static analysis tools (e.g., Coverity, Helix QAC) and sanitizers (e.g., AddressSanitizer) to detect pointer errors.

Apply ownership patterns to manage pointer lifetimes in complex systems.

Solve the linked list reversal problem using an iterative, in-place pointer approach.

Solve the linked list cycle detection problem using Floyd's Tortoise and Hare algorithm.

Implement in-place array manipulation algorithms (e.g., reversing, partitioning) using the two-pointer technique.

Solve problems involving precise buffer manipulation and the avoidance of off-by-one errors.

Explain pointer-based solutions and their time/space complexity clearly in a technical interview setting.
