Another situation is heap memory allocation should be synchronized with its precise use in almost any plan to ensure that it to become reused as much as feasible. One example is, if the only pointer to a heap memory allocation goes away from scope or has its worth overwritten in advance of free() is termed, then that memory can not be recovered for later on reuse and is essentially dropped to the program, a phenomenon often called a memory leak.
