Dynamic Memory Allocation In C Geeksforgeeks Code Example

Example 1: what is dynamic memory allocation in c++ In the dynamic memory allocation the memory is allocated during run time . The space which is allocated dynamically usually placed in a program segment which is known as heap . In this , the compiler does not need to know the size in advance . In C ++ , dynamic memory allocation means performing memory allocation manually by programmer . It is allocated on the heap and the heap is the region of a computer memory which is managed by the programmer using pointers to access the memory . The programmers can dynamically allocate storage space while the program is running but they cannot create a new variable name . Example : Example 2: dynamic memory allocation in c++ # include <iostream> using namespace std ; int main ( ) { double * pvalue = NULL ; // Pointer initialized with null pvalue = new double ; // Request memory for the variable * pvalue = 29494.99 ; // Store value

Android: Glide Not Showing Large Image From URL

Answer : I have found a solution that worked for my requirement. The override() method does the trick. Setting higher numbers for the target resolution seems to be the final workaround, but the bigger the numbers, the longer the time it would take to display the image(s), so it would be wise to implement a preloader/progressbar. Glide.with(getContext()) .asBitMap() //[for new glide versions] .load(url) //.asBitmap()[for older glide versions] //.placeholder(R.drawable.default_placeholder) .override(1600, 1600) // Can be 2000, 2000 .into(new BitmapImageViewTarget(imageViewPreview) { @Override public void onResourceReady(Bitmap drawable, GlideAnimation anim) { super.onResourceReady(drawable, anim); progressBar.setVisibility(View.GONE); } }); Custom centered preloader/progressbar placeholder indicator on relativeLayout xml: <ProgressBar android:id="@+id/progressBar" android:layout_wid

Bootstrap 4 Margin Auto Code Example

Example 1: bootstrap Margin and padding Use the margin and padding spacing utilities to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities, based on a 1rem value default $spacer variable. Choose values for all viewports (e.g., .mr-3 for margin-right: 1rem), or pick responsive variants to target specific viewports (e.g., .mr-md-3 for margin-right: 1rem starting at the md breakpoint). < div class = " my-0 bg-warning " > Margin Y 0 </ div > < div class = " my-1 bg-warning " > Margin Y 1 </ div > < div class = " my-2 bg-warning " > Margin Y 2 </ div > < div class = " my-3 bg-warning " > Margin Y 3 </ div > < div class = " my-4 bg-warning " > Margin Y 4 </ div > < div class = " my-5 bg-warning " > Margin Y 5 </ div > < div class = " my-auto bg-warning &q

An Iframe I Need To Refresh Every 30 Seconds (but Not The Whole Page)

Answer : You can put a meta refresh Tag in the irc_online.php <meta http-equiv="refresh" content="30"> OR you can use Javascript with setInterval to refresh the src of the Source... <script> window.setInterval("reloadIFrame();", 30000); function reloadIFrame() { document.frames["frameNameHere"].location.reload(); } </script> Let's assume that your iframe id= myIframe here is the code: <script> window.setInterval("reloadIFrame();", 30000); function reloadIFrame() { document.getElementById("myIframe").src="YOUR_PAGE_URL_HERE"; } </script> Okay... so i know that i'm answering to a decade question, but wanted to add something! I wanted to add a google calendar with special iframe parameters. Problem is that the calendar didn't work without it. 30 seconds is a bit short for my use, so i changed that in my own file to 15 minutes This worked for me. <script>

Automate Heroku CLI Login

Answer : The Heroku CLI only uses your username and password to retrieve your API key, which it stores in your ~/.netrc file ( $HOME\_netrc on Windows). You can manually retrieve your API key and add it to your ~/.netrc file: Log into the Heroku web interface Navigate to your Account settings page Scroll down to the API Key section and click the Reveal button Copy your API key Open your ~/.netrc file, or create it, with your favourite text editor Add the following content: machine api.heroku.com login <your-email@address> password <your-api-key> machine git.heroku.com login <your-email@address> password <your-api-key> Replace <your-email@address> with the email address registered with Heroku, and <your-api-key> with the API key you copied from Heroku. This should manually accomplish what heroku login does automatically. However, I don't recommend this. Running heroku login does the same thing more easily an

Wordpress - Add A Separator To The Admin Menu?

Answer : Here's a quick and dirty way to get what you want. Background WordPress stores admin menu sections in a global array called $menu . To add a separator you add an element to the $menu array using an index that is between the indexes of the options that you want to separate. Using the add_admin_menu_separator() function So I've written a function to encapsulate the logic for this I called add_admin_menu_separator() . You'll need to pick an array index number that is higher than the option after which you want to add a separator, and then call the function add_admin_menu_separator() passing said index as your parameter. For example: add_admin_menu_separator(37); The add_admin_menu_separator() function itself Here's the definition of the function add_admin_menu_separator() which you can copy into your theme's functions.php file. Yes it is arcane but then so is the code that creates and uses the global $menu array. (Plans are to eventu
