基于VC的滚动轴承信息录入与查询系统文档格式.docx

1、2.The Structure of Design2.1 Operation platform and development environmentThis procedure is in the Microsoft Visual C+ software platform has compiled, integrated development environment, can provide the editor C language, C+ and C+/CLI programming language.The integration of VC+ convenient debuggin

2、g tools, especially the integration of the Microsoft Windows programming （Windows API）, 3D animation DirectX API, Microsoft.NET framework.2.2 System structureAbove the synthesis analysis and development features of the platform, I decided to adopt the structure of data structure, the bearing design

3、for basic information data structure data, used to store multiple bearing information, the bearing inside diameter, outside diameter, width of models, such as data as the members of the structure, so as to realize the correspondence between the input and output of information.Figure 2-13.Program3.1

4、Flow chartImplementation of this function is mainly uses the switch statement.The first printf function in the operation of the interface type bearing inquiry system and functional module and its corresponding digital option.Then enter the operations to be performed by the switch statement options,

5、judge, and then into the different functions, different operation.Of course, to after an operation to call the menu function, is convenient for users to carry out an operation line.3.2 The contents of the programVC+6.0 environment compilerFigure 3-1Detailed C language program as follows#define N 100
