memory leak

Program sequences are always associated with the reservation of memory areas. If the reserved memory areas are no longer required after program execution, they are released so that they can be used by other programs.

A memory leak is a program error ( bug) that leads to a program not releasing reserved memory areas and, on the contrary, always reserving new memory areas. In this context, we speak of memory loss. Such a faulty program must be terminated and restarted because otherwise system errors will occur due to the lack of memory.
