What is memory leak detection and how does it work?

Memory leak detection is the process of identifying and fixing memory leaks in software applications. A memory leak occurs when a program allocates memory but fails to release it back to the system, leading to increased memory usage over time.

What are some common tools used for memory leak detection?

Some common tools include Valgrind, Visual Studio's Diagnostic Tools, and Memory Profiler for Python. These tools help analyze memory usage and identify leaks.

Can you explain how Valgrind works for detecting memory leaks?

Valgrind works by running your program in a virtual environment and monitoring memory allocations and deallocations. It reports any memory that was allocated but not freed, helping you pinpoint leaks.

Are there any best practices to prevent memory leaks?

Yes, best practices include using smart pointers in C++, regularly reviewing code for proper memory management, and utilizing automated testing to catch leaks early.
