What signs indicate a memory leak in an application?

Signs of memory leaks in an application include:

• Continuous increase in memory usage during the program's operation without releasing it.
• Slowing down of the application due to lack of available memory.
• Frequent crashes or abrupt termination with errors related to insufficient memory.
• Using memory profiling tools (e.g., Valgrind, AddressSanitizer) shows objects that are not released.

For example, if memory is allocated for objects in a loop but they are not deleted, the memory will constantly grow.
