similar to the second scenario, about the subclass, the note is similar to the first scenario, but the program is controlled by us and requires that it be properly relaxed.SummaryIn this section, we describe why inheritance is a double-edged sword, while inheritance is powerful, but inheritance can destroy encapsulation, while encapsulation can be said to be the first principle of programming, and inheritance may be misused, without reflecting the tr

How to execute analysis programs I) I am used to programming in advanced languages. A few lines of code can be used to implement complicated computing. Have you considered this, how can these lines of code be stored and run on a computer? In the face of such problems, I will share with you the specific process of program execution that I know. You may be confused. First, let's provide our sample
I. installation and configuration

Why do so many people like to create shortcuts? The reason is simple, is this way to use quickly, very convenient, most importantly, this shortcut is not to occupy what memory, and it does not represent a specific program, so even if the desktop encounter what crashes, program data loss, for these shortcuts , also does not have any effect, then these big and small shortcuts represent the Ghost Win7

"The first is to write a program, followed by the computer", which is the basic point of software development, software life cycle throughout the product development, testing, production, release, user use, version upgrades and maintenance of the long-term process, only easy to read, easy to maintain software code to have vitality.
In the actual software development process, may be due to the busy work, man
special optimization, optimized to an array, not even looking for, the value is the array subscript index, directly according to the value can find the address of the jump. Even though the values are not contiguous, but the numbers are dense and the difference is not much, the compiler may also optimize to an array-type jump table, with no values pointing to the default branch. The arrangement of case values in the program source code does not requir

Process: Create, destroy, create sub-process (fork), priority.
Threads: Create, suspend, resume, destroy, toggle, collaborate, sleep, wake up, wait, sync, lock, priority.
From the above description, you can basically clarify the relationship between the process and the thread. Finally, we summarize the followi
