When foreigners learn computer-related technologies, there is a great advantage, that is, there is no language gap. Many computer terminologies are actually the daily vocabulary in English, and usually act directly with that technical concept.

"Do not reinvent the wheel" Believe in everyProgramI have never heard of a sentence from a senior.Famous sayingHowever, I think this predecessor must be a pragmatic. If we just use it, we don't have to bother to implement all our functions. If we

The following is an example of an array:01 RECORD-X.03 month occurs 12 times.05 name pic x (12 ).05 days occurs 31 Tiems.07 comment pic x (20 ).07 TEMP-HI PIC s999.07 TEMP-LO PIC s999.77 current-day PIC 99.The call is as follows:Month (5): group

Man invented the programming language in order to control the machine. Computers are becoming more powerful, and programming languages are constantly being innovated. So I boldly believe that the meaning of programming language will be beyond the control of the machine, it may be a starting point of civilization-robot civilization. To better envision the programming language, let's take a look at its evolution. 1 The development of programming langua

the appropriate high-level language for compiling or interpreting programs.Currently widely used in the high-level language has basic, PASCAL, C, COBOL, FORTRAN, logo and VC, VB and so on. These languages are all part of the system software. (Learn about Content II)The computer can not directly accept and execute the source program written in high-level language, when the source program enters the computer, it is translated into the machine language

be constructed, it indicates that the problem is unsolvable. The Theorem Proving the incomprehensibility of this problem is a major breakthrough in algorithm theory. Qiu Qi's algorithm is the first such algorithm.1957 John Backus is the world's first high-order language: Fortran.1959 Grace Hopper has created the first modern compiler A-0 System and the commercial computer programming language "COBOL", known as the mother of

computing, FORTRAN(S mathematical computing language invented by the IBM team ), COBOL(Financial and business system development language (s) promoted by industry leaders such as IBM ), LISP(Used in the AI field, the main data structure is linked list. The full name is the list process language. It introduces many advanced features such as recursion, dynamic type, and automatic memory management) Algol(Use
