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 by using tools like garbage collection, and regularly check for unused objects.

What tools can I use to detect memory leaks?

You can use tools like Valgrind, LeakSanitizer, or built-in profilers in IDEs like Visual Studio to detect memory leaks.

Can you give me an example of a memory leak in code?

Sure! In C++, if you allocate memory using 'new' but forget to use 'delete', it creates a memory leak. For example:

int* ptr = new int[10]; // Memory allocated
// No delete ptr; leads to a memory leak
