What is the difference between memory leak and memory overflow?
Dec 03, 2020 pm 05:22 PM
Difference: Memory overflow means that when the program applies for memory, there is not enough memory space for it to use, and the system can no longer allocate the space you need; memory leak means that the program cannot release the applied memory space after applying for memory. , the harm of a memory leak can be ignored, but too many memory leaks will lead to memory overflow.
