This article mainly explains the "C++ Software example Analysis". The content in the article is simple and clear, and it is easy to learn and understand. Now please follow the editor's train of thought slowly and deeply. Let's study and learn "C++ Software example Analysis" together.

A key difference between C++ software and C is that C++ adds an abstract mechanism while completely retaining the efficiency of C. The so-called "modern C++ style" makes us feel the great charm shown by the unity of science and aesthetics.

C++ software test case generation is mainly to test some boundary values, such as * value, minimum value, 0 and so on. Suppose we want to test the member function of the following class: void strcpy (char* dest, char const * src), the software will automatically generate the following nine test cases:

< module name= "FileLength" / > < module name= "LineLength" > < property name= "max" value= "120s" / > < / module > < module name= "MethodLength" > < property name= "max" value= "300" / > < / module > < module name= "ParameterNumber" / > < module name= "RedundantThrows" > < property name= "allowUnchecked" value= "true" / > < property name= "allowSubclasses" value= "true" / > < / module > < module name= "VisibilityModifier" > < property name= "protectedAllowed" value= "true" / > < property name= "packageAllowed" value= "true" / > < / module >

It can be seen that if our code is implemented without special treatment for various possible situations (especially boundary conditions), then these potential problems can be easily found through C++Test. In addition, for some special test cases, we can also create test cases manually. In addition, the use of C++ Test can also help us to check the coding of the program and determine whether it is developed strictly according to the coding specification.

C++ Test is relatively simple to use, that is, it can be fully tested for a VC project, or only one C++ software can be tested at a time. In the trial, it is found that if the project is relatively large, do not automatically test a project directly, but test one by one according to the file, otherwise it will cause the program to die. Because it is developed using JAVA technology, it uses a faster machine when it is in use.

ProfileConf directly uses a third-party SNMP protocol package, while ProfileConfNew uses an encapsulated SNMP protocol package. One purpose of protocol encapsulation is to isolate third-party software packages, and the other is to simplify the operation of clients using SNMP protocol stack.

After the completion of the transformation, we use the software measurement tools of Together to measure the data. Select tools-- > metrics from the Together menu, which provides a large number of measurement indicators. As can be seen from the data, after the improvement, the code written has been reduced, saving about 1/3 of the code; the degree of coupling has decreased, but it is not particularly obvious, because we have changed our reliance on third-party protocol packages to our own woven protocol packages.

C++ software code complexity is greatly reduced, this is because we wrote the protocol package more in line with the actual use, so that the code is greatly reduced, very easy to learn, modify and maintain. The data speak for itself.

Thank you for your reading. The above is the content of "C++ Software example Analysis". After the study of this article, I believe you have a deeper understanding of the C++ software example analysis of this problem. The specific use also needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
