An alternative is the case of different structural structures. Structural conditions when using a condition check may result in two or more different processing processes. In a program that is about a menu example, because it provides the structure of the case, select different processing.(iteration repeat structure: structure or structure looping): allows multiple processes to be executed based on a condition. There are two basic structures that are duplicated and repeated for. Allows for repeated processing of a process definition for a loop structure, while the structure repeats the process until the condition is handled incorrectly.Details of the details of the structure will be presented in the course related Pascal language.Entry / exit list (single entry / exit):This is an important concept of structured programming. In / out single means that only one entry point and one entry point for each structure of the three structure are the starting and ending points in the control structure is the control structure.Logic program, which significantly improved because, when reading a program, the programmer can ensure that no matter what happens, in the structure, control structure, program structure only before a single point, many programmers used to control or transfer to m KH's ng program code, the other part of the in / out of loneliness. This will lead to a bad design program, very hard to read and check for errors and calibration. Write programs that would be like a bunch of wires! !150. Object oriented programmingOOP (object oriented programming method of Object Oriented Programming Oriented) is a new software development work, allowing the programmer to create objects (object oriented) method, combined with the data and command program. Traditional programming methods typically store data - files - for example, independent data manipulation programs. Therefore, each program must define how to use its own data. This usually causes code to be repeatedly installed, and more importantly, each data change program code must change them. With object-oriented program design, program and data binding in command after the object can be used many times, when we need a special command protocol (called methods) to define object response when the object is using the program.When using object-oriented programming programmers, you can define your object class (class). Each layer has a specific class of methods. In addition, the class of subjects is capable of the method through its class inheritance (low called inheritance). An object that takes out (instance) will contain all the methods from a higher level, plus a specific protocol. When an object gets a command to execute someone's instructions, it is a message (message). Unlike traditional programs that do not need to explain the information to the target know how to accomplish the goal only need to provide results. And how to execute an object defined in the protocol or inherit from the higher.
