During the interview, the interviewer mentioned the singleton mode. I have never touched on it, but I also understand it. This disappointed the interviewer with my impact. When I came back, I bought design patterns-the basis for reusable

This method is the method of today's colleagues. Seeing his PPT is concise, efficient, and clear, he wrote down his method: Write text: Write framework. The framework or content can be in the form of word to display the content. Find a

The following is an email from the President of the Institute of Engineering ***: Dear colleagues! We live and work together. In plain words, it is a fate. At least from my perspective, I hope that every colleague working around me can have a

Real-time mode: The addressing adopts the same 16-bit segment and offset as 8086. The maximum addressing space is 1 MB and the maximum segment is 64 KB. You can use 32-bit commands. 32-bit x86 CPU is used for high-speed 8086. Protection Mode:

There are two types of integer arithmetic operations in C language: signed and unsigned. In the unsigned operation, there is no symbol bit, so there is no concept of overflow. All unsigned operations are modeled on the Npower of 2. If one operand of

Running the executable moduleWhen an executable file is invoked, the operating system loader creates the virtual address space for the process. Then the loader maps the executable module into the process' address space. The loader examines the

Unfortunately, the returned value of dynamic_cast is not checked, resulting in a small bug. Another cup has been made. This is because I am working a lot. Some tasks are debugging and modifying others' bugs. It is very difficult to modify bugs

  Among all kernel objects, the event kernel object is the most basic. It contains a usage count (the same as all kernel objects) and a bool value (used to indicate whether the event is an automatic reset event or a manual reset event ), there is
