Ada is an unusually brave tank that will never be damaged. If you tell someone that you are driving Ada, they will laugh crazy, but, to be honest, would you like to drive a sports car on the battlefield?

a standard application development language. Almost all UNIX and Windows NT systems are developed using it. From the perspective of security, C seems to be very good, but due to its popularity, many of its security issues have been widely known, and these problems can also be easily exploited.For example, C performs very poorly on strings. It does not perform any automatic locating or cleanup, so programmers can handle everything on their own. When processing strings, most C programmers simply
What is the software development model?Software development model refers to the structural framework of all processes, activities, and tasks of software development. Software development includes the stages of requirement, design, coding and testing, and sometimes maintenance.The software development model can clearly and intuitively express the entire process of software development, and clearly defines the main activities and tasks to be completed as the basis of software project work.The earl

, engineers, accountants, and students all have the opportunity to use computers to solve problems encountered in their work. The birth of advanced languages has led to the rapid development of the software industry. At that time, Fortran was still not a structured programming language, and all variables in FORTRAN were global variables. It used similar methods to assembly for process control.
Over the next few years, a number of advanced languages, such as LISP, Algol, and

Caper Jones once put forward a keen Opinion, which was originally written in a series of informal records and later appeared in the book, as mentioned by friends who communicated with Brooks.
Caper Jones believes that it takes 10 years to write two equivalent COBOL programs, but one of them uses a structured method, and the other does not, the effect w

now develops towards the knowledge-based software engineering period.
---- But in general, with the changes in computer hardware (32-bit machines to 64-bit machines) and operating systems, the corresponding compilation systems must be modified. If you have a forward-looking consideration when designing a compilation system and leave room for the font length and some variable parameters, it will be easier to modify them.
---- Q: What are the major gaps between the research on compilation systems
There are two types of cursors: implicit and explicit. PL/SQL declares an implicit cursor for all SQL data operations, including query operations that only return one record..
In fact, Oracle's implicit cursor is used for every query operation in PL/SQL.
In addition, we can use a cursor to process a query result explicitly:
DeclareCursorC1IsSelectEmpno, ename, jobFromEMPWhereDeptno = 20;
A row set returned by a multi-row query is called a result set ). Its size is the number of rows that meet

I rummaged over the books that spread the case. These books are all about programming and system management. After so many years of working as a programmer, there have been countless projects and software. Every new friend asks me this so-called "Old Generation": Which language is the best? I always make a knowledgeable look, repeat the "knowledge" that I heard from older elders or some famous books ". Just like from the first day of learning programming, we were told by computer teach
