time to--dfs the two graphs and the edges of trees and atavistic.Since there may be multiple connected blocks, the starting point is enumerated in turn, and if u is not visited, then the connected block is traversed from u and the U is dyed first.If you are currently at node U, traverse the son V of U through the adjacency table, and note that when you enumerate V, you are going to leave the father of V to U. If it is found that V has not been traversed, then the V is dyed and then continues to

, MyBaseClass is the base class for Myderivedclass, and DoSomething () The version is included in the Myderivedclass. because base uses an object instance, using it in a static member produces an error .This keywordIn addition to using the Base keyword in chapter 9th, you can also use the This keyword. Like base, this can also be used inside a class member, and the keyword also references an object instance. Just this refers to the current object instance (that is, you cannot use the This keywo

1. Title: Randomly generate 30 to arithmetic questions, which cannot exceed 2-bit operations, including true fractions.2. Design Ideas(1) The first four numbers are randomly generated, the first two numbers are used as the arithmetic of integers, and then the first two numbers are then used as the second score, and the next two numbers as the number two.(2) Each case is represented by the Switch\case function, and the remainder by dividing by 7 represents a different case in 8, the first four re

, to carry out the next task.5, your team project is successful, if you will choose this team again, why success/failure;For:Our team work successfully, if again I will choose this team, because I think our team is not the most powerful, but there is a tacit understanding, because we have cooperated many times, no matter what project we can handle freely.The reason for success is nothing more than a tacit understanding of the cooperation, out of the small mistake, but quickly resolved, there is

the work I completed, but there are many needs to improve the place, see other students to make up the program, but also added a new question and answer system, Some can also enter the number of questions required, randomly generate the number of questions required, in the class, I will look at these people to make up the program, see how these features are realized, and learn from themselves. The programming language knowledge that this homework uses, I also will practise more, thoroughly gras

Advanced statement:Int (*f) ();Here the declaration has two parentheses, the second parenthesis is the function call, and the first parenthesis is the cluster effect. (*f) is a function, so f is a pointer to a function that returns an integral type. Each function in the program is in a location in memory, so there is a pointer to that location.int *f[];The subscript has a high priority, so f is the array, and the elements in the arrays are pointers to int.Int (*f[]) ()First, according to the pre

empty throw statement when catching and re-throwing an exception, to keep the call stack.To report an execution failure by throwing an exception instead of returning an error code.Do not let public members use exceptions as return values or out parameters. To indicate an error through an exception, do not indicate an error by using them as the return value.Avoid using exception handling to handle expected situations. Exceptions are designed specifically for the purpose of tracking exceptions, w
