Introduction This question is related to a common error in C++ programming, which is the “expected ‘)’ before object. class does not name a type” error. This error occurs when the programmer attempts to use a class name as a type, but the class has not been declared. In this article, we will discuss the … Read more
You would just set the .textContent of the element that it will be shown in to the variable. No hiding/showing of the element is needed because the element’s .textContent will be empty at first (so it will initially not show anything anyway). <html> <head> <title>Using form data in the page</title> </head> <body> <div> <input type=”text” … Read more
I’ll leave finding out how to generate a magic square as an exercise. If you’re still having trouble with it, you can find other questions on StackOverflow about how to generate a magic square of a given size in Python. Once you have your 3×3 magic square magic(3) (as a numpy ndarray), you can obtain … Read more
Introduction A magic square is a square grid of numbers where the sum of each row, column, and diagonal is the same. In this tutorial, we will be discussing how to find all possible 3×3 magic squares using Python. We will be using a combination of loops and if-else statements to generate all possible magic … Read more
It seems like you really need to go back and start with the basics of Android and Internationalization. It is not possible to update a resource at runtime, as you have correctly discovered, so it is your approach that needs to change. Here is an example: TextView text; String value = getString(R.string.knife); text.setText(value); It seems … Read more
stringVariable = [NSString stringWithFormat:@”%i – %@”, intVariable, stringVariable]; solved Put in string int and text [closed]
Yes, it does cause overflow. Luckily your program is short enough that you didn’t notice the damage. Your code writes 8 bytes into a 4 byte variable. This will scribble on whatever follows a in memory. In your case there are no declarations after a, so it probably wrote over free space, but that’s not … Read more
Really had the warning in iOS dev center: 5 Xcode Developer Preview can not be used to submit apps to the iOS or Mac App Store. Continue to use the publicly released version of Xcode to compile and submit apps to the App Store. However, given the circumstances, I did not see cause to release … Read more
To answer your last point which is interesting (the other parts of the question are best answered by a debugger), a double that is too large for an int will cast into the largest possible int; similarly for a double that is too small for an int will cast to the smallest possible int. See … Read more
You want to traverse your linked list while the value isn’t null. If you come across the value you’re trying to delete, delete the node, rework the links, and return. Your function should look like this: public void deleteNode(int value) { if(count == 0) { return; } else if (count == 1){ // delete this … Read more
Make your entity class implement Comparable<EtatCaution>. public int compareTo(EtatCaution compareObject) { return lbEtatCaution.compareTo(compareObject.lbEtatCaution); } Then, just call Collections.sort(myList). 8 solved How do I sort a List in Java? [closed]
Like matszwecja said your input is a string and not callable. Also you are trying to execute a string with class.name in your class a which is not possible. If you really want to use classes it would look like this. class a: def name(self): print(“option a”) class b: def name(self): print(“option a”) class c: … Read more
To fill the height, you need to add a min-height heigher than the default. By default, the height is calculated to fit-content. body { margin: 0; } .wrap { display: flex; flex-flow: column; min-height: 100vh; } .one { background: yellow; flex: 1 0 0; } .four { background: red; flex: 4 0 0; } <div … Read more
Pluck will still return a collection. You’d need to iterate through it, either with another foreach loop, or such as through map, etc: @foreach($amazings as $product) @foreach($product->prices->pluck(‘value’)->all() as $val) {{ number_format($val) }} @endforeach @endforeach solved number_format(): Argument #1 ($num) must be of type float [closed]
The immediate problem in this code is that you’re storing pointers to the string parameters in your record. Those pointers are addresses in your main process; they are not valid in the target process. You should store those values in fixed-size arrays in your record, just like you’re already doing with the module and function … Read more
