1. Assume that a C program has two files: p1.c and p2.c. On an ia32 server, we compile the code using the Unix Command Line as follows: UNIX> gcc-O1-o p p1.c p2.c In fact, the GCC command calls a series of programs to convert the source code into executable code. First, the C Preprocessor extends the source code, inserts all files specified with the # include command, and extends all the macros specified with the # define declaration. Then, the compil

shared by all processes. The properties of the file are mostly saved.For the above program, there are two open file tables, each file table holds the location of open files, they are independent of each other, so in the last read, read a.Of course we don't use these system-level functions most of the time when we write programs, and we've already developed a set of standard IO functions for us to use, such as Printf,fopen,fread.The communication and

Read the tip: This article will tell you how to take advantage of C # 's fantastic features to implement a plug-in architecture and build a scalable solution with a plug-in (plug-ins) mechanism. The C # language under the. NET Framework, and others. NET language provides a lot of powerful features and mechanisms. Some of them are brand new, while others are copied from the previous language and platform. However, this ingenious combination produces so

Thinking logic of computer programs (27), thinking 27 In this section, we will continue to discuss the packaging class, mainly the Integer class. Next we will introduce the Character class. Long is similar to Integer, so we will not discuss it separately. Other classes are basically introduced and will not be described again. What else do I need to introduce to a simple Integer? It has some binary operation

Thinking logic of computer programs (26) and thinking 26 Packaging Java has eight basic types, each of which has a corresponding packaging class. What is the packaging class? It is a class that contains an instance variable and stores the value of the corresponding basic type. This class generally has some static methods, static variables, and instance methods to facilitate data operations. In Java, the bas

vain. So here are some tips for beginners if the computer doesn't respond when you're doing something important, do not go to the mouse, try to close the window, because the program has no response has been explained that the computer's internal program is not smooth, and then to point the mouse is equivalent to increase the burden of the computer, is tantamount to worse, you say no response to the program

Thinking logic of computer programs (87) and thinking 87 In the previous section, we discussed dynamic proxies. in the previous sections, we mentioned ClassLoader for many times. This section will discuss in detail the class loading mechanism and ClassLoader in Java. ClassLoader is the Class for loading other classes. It is responsible for loading bytecode files to the memory and creating Class objects. Lik

Thinking logic of computer programs (29) and thinking 29 This section describes the Character encapsulation class Character. String operations are probably the most common operations in computer programs. Java indicates that the String class is String. This section describes String in detail. The basic usage of strings

I. Basic concepts of BIOS When talking about bios, have you been concerned about it? In fact, whenever you press the power key on the chassis, it will really work for you. So what is bios? The book gave us a definition: "BIOS is short for Basic Input-Output System (Basic Input-Output System). It is responsible for initializing, setting, and testing various system hardware at startup, to ensure that the system works properly. If the hardware is abnormal, stop working immediately and report the er

Thinking logic of computer programs (24) and thinking Logic The basic types, classes, interfaces, and enumerations we introduced previously are all used to represent and operate data. There may be many errors during the operation process, and there may be many causes of errors, some are uncontrollable internal reasons, such as insufficient memory, full disk, and some are uncontrollable external reasons, suc

Thinking logic of computer programs (19), thinking Logic Restrictions on Data Types Previously, we have been saying that programs mainly involve data and data operations. To facilitate data operations, the advanced language introduces the concept of data types. Java defines eight basic data types, A class is equivalent to a custom data type. It can represent and
