A series of steps are to determine, through a puter to guide the process. NonProcess Language Using traditional assembly language, piler language and interpretation of language, programmers determined to tell a puter exactly how to solve the problem of process. However, the use of modern nonprocess language, and sometimes said that the fourthgeneration language or languages, programmers need only simple logic to determine the relationship, so the language transform procedures calculated how to solve the problem. The nonmercial use of language examples are: Prolog, Focus, Lonusl2 3 and other, and so on. They are being increasingly popular. 3 libraries Programmers envisaged to prepare a huge procedure, when the type of statement, it may be editing procedures, both on the disk. Because the procedure can not be used huge booking a write all the time, so programmers eventually have to stop typing, and the type of procedure has been adopted to the disk drives. When work resumed later, the floppy disk reinserted, the new source statement by typing in the back. The same can be preserved for some other disk source code written by programmers and even some of the other procedures. The source of the statement is a good example of that. Finally, the pletion of the type and source piler, the target modules can be directly loaded into main memory, but more often it deposited in the target module library. Because the target module is binary machineclass subroutine, a target module generated by the pilation process and FORTRAN piler (or any other piler) have no fundamental differences. Therefore, the language used different source modules and that the objective can be stored in the same stored procedure. Some of modules can be loaded to the main deposit, and was implementation. While other modules, including some of the subroutine call, the goal of these subroutine modules are not part of. For example, a puter simulation poker the procedure, if someone previously prepared for a very good brand of procedures, then reuse that subroutine is meaningful. 4 program development process Procedures how to amend the package? More generally speaking, professional programmers how to prepare the original procedure? Part procedure is not entirely a scientific, but also to point arts. Therefore, different programmers use different methods for procedures is nothing strange. However, most programmers are careful definition of problems from the start, and then write code in detail before design solutions. Let us briefly examine the procedures for the development process. the definition of the problem Program development is the first step in problem definition, which appears to be mon sense, but it often is not clear why certain procedures need to e out for the definition of a failure to correct the problem by the results, even if the result is a great, but also useless. Because people need information before writing process, the programmer should be clear after the desired information can start writing. Then, have that information to determine the algorithms or rules. Given the requested information and the output method, the data will have to import identified a result, a clear definition of the problem to the programmer a good idea
