What are memory leaks and how can I prevent them?

Memory leaks occur when a program allocates memory but fails to release it, leading to reduced performance. To prevent them, ensure proper memory management practices, like using smart pointers in C++ or garbage collection in languages like Java.

Can you give me some examples of how memory leaks happen?

Sure! Common examples include forgetting to free memory after use in C/C++, retaining references to objects that are no longer needed, or creating circular references in languages with garbage collection.

What tools can I use to detect memory leaks?

You can use tools like Valgrind for C/C++, Visual Studio's built-in diagnostics for .NET applications, or memory profilers like YourKit for Java.

Are there any best practices to follow?

Yes! Always initialize pointers, use RAII (Resource Acquisition Is Initialization) in C++, and regularly review your code for unused objects.
