Problem:After converting std:string to char* from a C + + file, the char* containing the IP address needs to be extracted from the IP address in the string char*; Solution:1. Solution Idea:The maximum IP address is 12 characters + 3 periods = 15 characters, the general expression is 192.168.111.111;Can be parsed from the first character when it is not '. ' , save all the characters and convert all the saved characters to 16. 2. The procedure is as follows: Copy Code code as follows:

); } Part → list of solid bodies To access all solid bodies in a part, use the "bodies" property to access the Body Collection. Then use the collection's iterator to access each body. public static void processPart(Part partObject) { BodyCollection bodyList = partObject.bodies(); BodyCollection.Iterator itr; for (itr = bodyList.iterator(); itr.hasNext();) { Body bodyObject = (Body) itr.next(); processBodyFaces(bodyObject); processBodyEdges(bodyObject); } } Solid

While loop:The while loop in the Python process control until the expression becomes false to end. Expression is a logical expression that must return a true or falseThe syntax is as follows:While expression:Statement (s) #请注意while循环也是要遵循代码缩进原则的While followed by true condition:print ' #始终为true, will go into the dead loop, printing prints all the time. , no practical significance.Then, when we design a Python program, we set a condition that terminates

The K-Nearest algorithm (KNN) is a very intuitive method for classifying by measuring the distance between different eigenvalue values. This paper mainly records examples of improving dating sites using KNN algorithm.Task one: Classification algorithm classify0is to use the distance formula to calculate the distance between the eigenvalues, select the nearest K-point, and by counting the results of this K-point, the predicted value of the sample is obtained.The tile function usage is hereThe Arg

frequently occurring categories in the K most similar data. The algorithm is described as follows:1) Calculate the distance between the point in the data set of the known category and the current point;2) Sort by the increment order of distance;3) Select K points with the minimum distance from the current point;4) Determine the occurrence frequency of the category of the first k points;5) returns the category with the highest frequency of the first K points as the predicted classification of th

The distance to get these two points is 0.3606.When we have a sample of the data and the classification of the data, we enter a test data, and we can find out according to the algorithm which category the test data belongs to.KNN Algorithm Implementation process: Calculates the distance between the test data and each sample data. Sort by distance increment Select the nearest K-point from the test data (note that the K valu

point weight of the distance is small.2, the calculation is large, each sample to be classified to calculate it to the distance of all points, according to the order of distance to find K adjacent points, the improved method is: first to the known sample points for editing, in advance to remove the small sample of the role of the classification. Applicability:It is suitable for automatic classification of the class domain with large sample capacity, while the class domain with smaller samp
