A memory leak (that is, a corresponding free () call within malloc () is never freed after execution) and a buffer overflow (for example, writes to memory previously allocated to an array) is a common problem that may be difficult to detect.

Recent projects frequently appear oom problems, various path testing, memory trend analysis, all kinds of logical reasoning to finally locate the problem. In this process and group of students to discuss the time found that some students of memory leaks and memory overflow concept is not in place, resulting in a more e

cause of memory leaks!Garbage collection mechanismGarbage collection (garbage collection, referred to as GC) automatically empties objects that are no longer used in the heap. In Java, objects are used by reference. If no reference is directed to the object, the object is not processed or called, and the object is called unreachable (unreachable). garbage collection is used to free up

1.c++ memory leak definition: Memory leak leak refers to a situation in which a program fails to release memory that is no longer in use due to negligence or error. A memory leak does not mean that there is physical disappearance, but that the application allocates some memory
