Instead of: class MyClass { private int _value; public MyClass() { _value = OtherClass.StaticInt; } } Favour: class MyClass { private int _value; public MyClass(int valueForConstruction) { _value = valueForConstruction; } } Decouples MyClass from OtherClass, even if you do this: MyClass c = new MyClass(OtherClass.StaticInt); 2 solved Access static property in another class’s non-static … Read more

This line fprintf(l_pFile, sVar); doesn’t look right. I think it should be fprintf(l_pFile, “%s\n”, (LPCTSTR) sVar); The loop could become infinite if the file has less than two linefeeds: while(count != 2) I think it should be: while( (count < 2) && ( ! feof(l_pFile) ) && ( c != EOF ) ) Probably unrelated … Read more
If you mean what should happen, this is what it should return Mathematically the factorial function is also defined as gamma(n+1)=n!, there is also these relations n*gamma(n)=gamma(n+1) and gamma(1/2)=sqrt(pi) Using these you can get the factorial for any non-integral negative number for more information see this solved What SHOULD happen if a negative value is … Read more
You must use echo for print value like: echo “<td><a href=””.$row[“url’].”‘>”.$row[‘url’].”</a></td>”; or <td><a href=”https://stackoverflow.com/questions/60163422/<?php echo $row[“url’]; ?>’><?php echo $row[‘url’]; ?></a></td> 2 solved echo value from DB as a Link in PHP/HTML table [closed]
If you can’t use std::map, you can associate the word with the frequency: struct Info { std::string word; int frequency; }; //… std::vector<Info> database; //… std::string word; while (std::cin >> word) { // Find the word: const size_t length = database.size(); for (unsigned int i = 0; i < length; ++i) { if (database[i].word == … Read more
You need to have a div with the id. This code increments the value. Also, you don’t need both document.write and setting the innerHTML.

This is a very large question. And a hard task. I think, the easy way is to extract one frame by second if the source is a video stream. Then use OpenCV to make a face detection. Once you got the faces, feed a NN for recognitions. Some links for face recognition in Deep Learning: … Read more
