And, since you seem new here, let me tell you a thing that saved a few stock exchanges I worked for. You don't always need to manage the memory at all. Many of the things you want to do in high-performance software are either in the stack or in heap memory that you allocate only once and never release. If the long story short is that if you're in need of managing memory, you're probably doing whatever you're doing wrong. Not always, but often the case. That is why I am very skeptical about languages that do so much to prevent you from managing memory. To me, they are solving the wrong problem: you shouldn't be needing their help at all to begin with, and if they help you being safer, it very probably means your logic around resource management was already wrong and could be helped by a completely different approach.
