Memory Pool: the memory pool is used by the program to apply for a large enough memory from the operating system in advance. After that, when the program needs to apply for memory, it does not apply directly to the operating system, it is obtained directly from the mem

best way to show their ability to the outside world, many programmers have high programming skills, the ability to express, Linux can succeed, in addition to the power of the network community, but also due to the Linux author himself to the major foundations of letters, promotion, Imagine if there is no good written language skills, even if the Linux system is excellent, but can not be accurately expressed, losing the support of the major foundation

Since I started learning program design, I have been talking about object-oriented. When I first came into contact with C ++, I was really fascinated by its oo features. It is more colorful than the previously used C language. I thought that I was always proud to write a class for a long time. Now I have been a programmer for some years. Looking back, I have learned some new ideas about oo.I. objects outside the code When talking about Oo, everyone wi

to programming, because the purpose of programming is to serve life, if a programmer is not familiar with life, how can he write a program? So from now on, let's take a look at our daily lives. It was a bit difficult to understand at first, and then I thought it was really the case.
