The shorthand property to set all the animation properties is animation. It sets the animation duration, animation name, etc.You can try to run the following code to work with animation shorthand property:ExampleLive Demo div { width: 150px; height: 200px; background-color: yellow; animation: myanim 2s } @keyframes myanim { from { background-color: green; } to { background-color: blue; } }
We should avoid using global variables in any language, not only C++. This is because these variables pollute the global namespace, can cause some very nasty bugs in big projects as they can be accessed from any file and hence be modified from anywhere. These are some of the reasons why global variables are considered bad −Global variables can be altered by any part of the code, making it difficult to remember or reason about every possible use.A global variable can have no access control. It can not be limited to some parts of the program.Using global variables causes very ... Read More
Use the [attribute ~= "value"] selector to select elements with an attribute value containing a specified word with CSS.You can try to run the following code to implement the [attribute ~= "value"] selector. Here, the word we are searching is “Tutorials”,ExampleLive Demo [alt ~= Tutorials] { border: 5px solid orange; border-radius: 5px; }
You can try to run the following code to implement the animation-timing-function property:ExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo1 {animation-timing-function: ease;} #demo2 {animation-timing-function: ease-in;} ease effect ease-in effect
Undefined behavior is a way to give freedom to implementors (e.g. of compilers or of OSes) and to computers to do whatever they "want", in other words, to not care about consequences.The cases in which segmentation fault occurs are transient in nature. They won't always result in a segmentation fault but can also run correctly(or at least appear to). For example, consider the following code fragment −#include int main() { int arr[2]; arr[0] = 0; arr[1] = 1; arr[2] = 2; // Undefined behaviour arr[3] = 3; // Undefined behaviour ... Read More
Use the animation-play-state property to set whether the animation is running or paused.You can try to run the following code to implement the animation-play-state property:ExampleLive Demo div { width: 150px; height: 200px; position: relative; background: red; animation-name: myanim; animation-duration: 2s; animation-play-state: paused; } @keyframes myanim { from {left: 0px; background-color: green;} to {left: 100px; background-color: blue;} }
Use the animation-name property to set the name of the @keyframes animation.You can try to run the following code to implement the animation-name property:ExampleLive Demo div { width: 150px; height: 200px; background-color: yellow; animation-name: myanim; animation-duration: 3s; animation-delay: 3s; } @keyframes myanim { from { background-color: green; } to { background-color: blue; } }
Use the animation-iteration-count property to set the number of times an animation should be played with CSS.You can try to run the following code to implement the animation-iteration-count propertyExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo1 {animation-timing-function: ease;} #demo2 {animation-timing-function: ease-in;} ease effect ease-in effect
C++ STL includes useful generic functions like std::for_each. Unfortunately, they can also be quite cumbersome to use, particularly if the functor you would like to apply is unique to the particular function. So this function that you'll create will be in that namespace just being used at that one place. The solution to this is using anonymous functions.C++ has introduced lambda expressions in C++11 to allow creating anonymous function.example#include #include #include // for_each using namespace std; int main() { vector myvector; myvector.push_back(1); myvector.push_back(2); myvector.push_back(3); for_each(myvector.begin(), myvector.end(), [](int x) { ...

Use the CSS background-origin property to set the border-box value. With the border-box value, the background image begins from the upper left corner of the border.You can try to run the following code to implement the border-box value:ExampleLive Demo #value1 { border: 3px solid blue; padding: 30px; background: url(https://www.tutorialspoint.com/assets/videotutorials/courses/html_online_training/380_course_216_image.jpg); background-repeat: no-repeat; background-origin: padding-box; } ...
