You could add elements if your array is big enough and you manage its actual size manually (and make sure it stays below the max allocated size). You just have to copy all the elements above the insertion point to higher locations (based on how many items you want to insert), which is very inefficient. … Read more
This is not even “valid” code (It would be basically valid, 20 years ago, when variables without type were assumed to be ints). /*int*/ x(/*int*/a,/*int*/ b){ float *a,*b; while(*a++ = *b++); } In the following, I will assume, that a and b are int* (At least in the parameters) This is undefined behavior. float *a,*b; … Read more
Here is the flow of the code you have shared 1. When the component mounts, it calls a function 2. this function “fetchPostsWithRedux” then dispatches actions also, it send an api call to server to fetch data 3. when the data is received component re-renders with updated data as prop. Now if you want to … Read more
Try this; Button btn; btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, “abc….”, Toast.LENGTH_LONG).show(); mTextView.setTextColor(Color.parseColor(“#bdbdbd”)); } }); solved How to make button do 2 events? [closed]
You could use a dynamic approach for any size of items, by taking one element out of the array, get the rest combinations and later put that element to the former position into the array. Then take the actual element and add it to the result set. Then try to get the combinations of the … Read more
As you are using WebForms the easiest is to change your ASPX to: <label ID=”myLabel” runat=”server” ClientIDMode=”Static” for=”Rdb_1″>No</label> and then in code behind: myLabel.InnerText However I would suggest you investigate using a label control as that would be even easier to use. solved How to get text value of HTML label in c# in ASP.NET … Read more
your code can be simplified: public bool CheckStudents(int students) { if(this.firstyear && students < 150) { return true; } return false; } Remember, the function returns as soon as the any return statement is hit. You don’t need to check for every case, only the cases where you won’t return false. solved Error message ‘not … Read more
The first line does the cluster analysis, and stores the cluster labels in a component called cluster_iris$cluster which is just a vector of numbers. The second line puts that cluster number as a categorical label onto the rows of the original data set. So now your iris data has all the petal and sepal stuff … Read more
<?php $integers=”1,5,8,4,3″; //Convert into String $arr = explode(‘,’, $integers); // String to Array Conversation foreach ($arr as $key => $value) { $val[] = “‘”.$value.”‘”; // add your requirements here } $finalvalue = implode(‘,’, $val); // Array to string echo $finalvalue; // your final result ?> solved Convert integer to string
A naïve approach would be to do the following. Console.WriteLine(“Add integer X: “); int x = Convert.ToInt32(Console.ReadLine()); Console.WriteLine(“Add integer Y: “); int y = Convert.ToInt32(Console.ReadLine()); Triangle Tri1 = new Triangle(x, y); Console.WriteLine(“Area 1=” + Tri1.TriArea()); A more robust approach would be to validate user input and have an input loop so that the user can … Read more
You can create an array with the references to the labels: Label[] labels = { eLabel1, eLabel2, eLabel3, … }; Producing an array with the texts from the labels would be a one-liner: string[] values = labels.Select(l => l.Text).ToArray(); solved c# faster way to read all textboxes/labels [closed]
So I see two glaring errors, the first of which is what the compiler is telling you, namely that real and imaginary have not been declared anywhere. In Java, you cannot use a variable unless you have previously declared it. You probably want to have a real and imaginary component of your ComplexNumber, so you … Read more
If you do not have a constructor the Java compiler will create a no-arguments constructor for you. As soon as you provide a constructor which has arguments the no-argument constructor does not get created by the compiler. So if you add a no-arguments constructor to InVoice (like below) it should work. public InVoice() { } … Read more
static void placeRandomly2D(int[][] arr, int limit) { // generates value [0…limit) half-interval and places it into the 2D array arr // at random position; limit must be positive Random rand = new Random(); int value = rand.nextInt(limit); int pos1 = rand.nextInt(arr.length); int pos2 = rand.nextInt(arr[pos1].length); arr[pos1][pos2] = value; } And, just in case, version for … Read more
the Intent constructor accepts two arguments. first argument is your Context and the second one is your Activity class. in your fragment, you can access your Context via getActivity method. here is what you should do : Intent i = new Intent(getActivity(), MyActivity.class); 0 solved calling an activity from fragment activity through Intent [closed]
