Progress bars can be styled with the progress[value] selector.
This example gives a progress bar a width of 250px and a height of 20px

<progress max="100" value="20">
<div class="progress-bar">
<span style="width: 20%;">Progress: 20%</span>
</div>

C99
Since C99, C has variable length arrays, VLA, that model arrays with bounds that are only known at initialization time. While you have to be careful not to allocate too large VLA (they might smash your stack), using pointers to VLA and using them in sizeof expressions is fine.

The following example creates a FileSystemWatcher to watch the directory specified at run time. The component is set to watch for changes in LastWrite and LastAccess time, the creation, deletion, or renaming of text files in the directory. If a file is changed, created, or deleted, the path to the f...
A common mistake a lot of people starting out with FileSystemWatcher does is not taking into account That the FileWatcher event is raised as soon as the file is created.
However, it may take some time for the file to be finished .

Suppose we have an array of integers and we want to figure out the maximum value without holding the whole array in memory all at once. This approach can be adapted to handle a variety of other situations in which data needs to be processed while being deserialized instead of after.

Many bugs in knockout data binds are caused by undefined properties in a viewmodel. Knockout has two handy methods to retrieve the binding context of an HTML element:
// Returns the binding context to which an HTMLElement is bound
ko.contextFor(element);
// Returns the viewmodel to which ...
