Recently, we have been working on a project using VC6. Some of our brothers have reflected that they do not quite understand the differences between pointers and references. Currently, developers are familiar with Java, C #, and other languages, which is farther and farther away from the underlying operating system, so that most people have forgotten some things in C/C ++.Speaking of pointers, anyone who has learned C language is no stranger. This is

Through the initial study and online information query know that the Java language is a multi-purpose language, concurrent language, class-based, object-oriented language. Java is a multi-functional high-level language, the Java language was first known as Oak, its author is James Gosling.ed Frank, Patrick Naughton, Jonathan Payne, Chris Warth added a number of features to the Java language for the next few years, making it possible to develop small programs for Web pages (applets), applications

after continuous learning and deepening of Java, we've got some basics of java. subsequentlyThis week studied the handling of anomalies. Exceptions in the program, which generally become out of the box, can be understoodis not normal, other programming languages also have such a situation, Java also exists insideFor such an architecture, we need to be clear that exceptions and errors are not a concept.The T

This week through the third chapter of the study, found that they lack of place. A teacher's assessment of a class can help him find out how much he has mastered the knowledge and keep himself moving forward.The Java and C languages are basically similar in algorithm but somewhat different in syntax. There are some grammatical problems when writing a program, and the output of that piece sometimes does not know which one to choose. The opening and wri
