Kirat[ad_1] I have a feeling you are looping in the view with something like <%= posts.each do |post| %> if you remove the = such as <% posts.each do |post| %> the data will no longer be displayed. In very simplified terms: <%= means display this data. each will return the original object so you … Read more
[ad_1] The CPython implementation – the implementation of Python written in C – uses the C language to implement a certain kind of variable lookup that makes Python behave like Python and not like, say, C or BASIC. So, you can certainly use C or C++ to implement string-named variable lookup. Just don’t expect the … Read more
[ad_1] Assuming the “Student” type is a reference type (class), and not a value type (struct): Student s = new Student(); Memory for a new Student object is allocated, and a new reference “s” is created and set to refer to the new memory. Student s2 = s; A new reference “s2” is created and … Read more
[ad_1] Your message functions lack a return type. C deduces it to be int. However, not returning a value from a non-void function is Undefined Behaviour. In your case, the return value from printf has probably been stored in a register, which was not overwritten by message before it itself returned. Thus, the return value … Read more
[ad_1] Basically, WordPress is not built in a way to allow you that. It just goes on pushing its output whenever it wants, and when any of your filters is executed it is either before any output happened (so you have nothing to modify) or after (so it is already gone away to the browser). … Read more
[ad_1] if Enter == “Yes” or “yes”: This is not how or works. This is interpreted as if (Enter == “Yes”) or “yes”:. In python, non-empty strings are always true, so all of the if statements like that will be true. I would suggest something like if Enter.lower() == “yes”: which takes care of all … Read more
[ad_1] I don’t think you should access the DB server right away from Android App. You need to have a web service implemented to talk with your db server. Web Service can function as the layer between your DB and Android App. If you use the web service deployed in the same local area network … Read more
[ad_1] You can reverse an array like this: public void reverse(Object [] a){ for(int i = 0; i < a.length / 2; i++){ Object temp = a[i]; // swap using temporary storage a[i] = a[a.length – i – 1]; a[a.length – i – 1] = temp; } } It’s worthy to note that it doesn’t … Read more
[ad_1] for (a = 2; a <= 10; a++) { for (i = 2; i < a; i++) { if (a % i == 0) { m = false; } } if (m == true) { Console.WriteLine(a); } m = true; //<<******* Add this line } of course some speed up is always possible for … Read more
[ad_1] Based on the threads Ive read on here, setting a pointer to deadbeef will make the pointer null. No, that is incorrect. Although deadbeef is a common “nonsense pattern”, it is definitely not equal null. A common reason to set pointers (more generally, a memory area) to a known and unusual pattern, such as … Read more
[ad_1] Do something like for(int i=0; i< GroupOfPeople.Count; i++) { GroupOfPeople nm = (GroupOfPeople) nm.GroupOfPeople[i]; if(i < GroupOfPeople.Count – 1) names += nm.FirstName + “, “; else names += ” and ” + nm.FirstName; } [ad_2] solved C# ASP.NET for loop issue [closed]
[ad_1] Okay to explain it in a more complete way. The most other guys had already wrote that you have to use ‘->’ when ever you have a pointer. But you could also do this with ‘.’, to do this you must respect the priority of the operators. We need the ‘*’ to get the … Read more
[ad_1] The rule of thumb on assigning an object of one type to a reference of another type is the “isA” test. If your super class is Fruit and subclass is Banana, you can assign: Fruit obj = new Banana() if Banana isA Fruit. I suggest you get a good understanding on inheritance and type … Read more
[ad_1] Textarea’s don’t have a value attribute. The content gets wrapped in the <textarea> tags: <textarea id=”element_5″ name=”Description” class=”element textarea medium”> <?php echo $person[‘description’]; ?> </textarea> 4 [ad_2] solved Echoing PHP in HTML [duplicate]
[ad_1] The table can be pretty formatted in Pandas by assembling the two missing formatting conditions into a single df. I made the following two changes to the original code. Hide index numbers with hide_index() df[[“Unit”, “Abbreviation”, “Storage”]].style.hide_index() To apply to a subset of columns, you can use the subset parameter. Left align the first … Read more
