A memory leak is a type of resource leak that occurs when a program keeps allocated memory after it has finished using it. This can lead to a number of problems, including performance degradation and system instability.
There are a number of ways to check for memory leaks. One common method is to use a memory profiler. A memory profiler is a tool that can track the allocation and deallocation of memory in a program. This can help identify any areas where memory is not being properly released.
