My hobby project Med is written in C++. A lot of implementations need to use dynamic memory allocation and instantiation. Because complex data is impractical to be passed by value, like the case of JavaScript object and array. Since C++ doesn’t have garbage collection, it is possible that the developer doesn’t free/delete the dynamically created memory properly.

As in my project Med, the program will retrieve the memory from other process. That means, it needs to make a copy of the scanned memory. And this will involve creating dynamic memory (using new operator). When using the program to filter the memory to get the target result, it needs to get a new copy of memory with the updated values, then compare with the previous copy. The unmatched will need to be discarded (free/delete); the matched will need to replace the old one (also free/delete the old one, because the new one is dynamically allocated).
