garbage value of each region, that is, the amount of space and time it takes to reclaim the region, and then maintains a priority queue, recovering one of the most valuable region per time, based on the allowable collection times.To avoid the garbage collection problems caused by the cross-referencing of each region, each region of G1 has a remembered Set that stores references to other region's objects in this region. When a memory is reclaimed, this part is also added when enumerating GC root

In C ++ programming languages, security operations on programs are also relatively simple. We can manage program security through C ++ hosting programs. So how can we implement this function correctly? Here we will introduce the concepts of C ++ hosting programs in detail.

Study on Stack management during program running in windows The following code draws a conclusion: In a windows operating system, the stack space will not be released, but if the existing stack space meets the function running requirements, a new stack space will not be applied for, but the stack space will not be released after the function exits; if the function runtime space is insufficient, you need to
