Use the animation-delay property to set a delay for the start of an animation with CSS:ExampleLive Demo div { width: 150px; height: 200px; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-delay: 2s; } @keyframes myanim { from { background-color: green; } to { background-color: blue; } }
static_cast − This is used for the normal/ordinary type conversion. This is also the cast responsible for implicit type coersion and can also be called explicitly. You should use it in cases like converting float to int, char to int, etc.dynamic_cast −This cast is used for handling polymorphism. You only need to use it when you're casting to a derived class. This is exclusively to be used in inheritence when you cast from base class to derived class.Regular Cast − This is the most powerful cast available in C++ as it combines const_cast, static_cast and reinterpret_cast. but it's also unsafe ...

The input type button can be a submit button or reset button. With CSS, we can style any button on a web page.You can try to run the following code to style input type button:ExampleLive Demo input[type=button] { background-color: orange; border: none; text-decoration: none; color: white; padding: 20px 20px; margin: 20px 20px; cursor: pointer; } Fill the below form, Subject Student
argc stands for argument count and argv stands for argument values. These are variables passed to the main function when it starts executing. When we run a program we can give arguments to that program like −$ ./a.out helloExampleHere hello is an argument to the executable. This can be accessed in your program. For example,#include using namespace std; int main(int argc, char** argv) { cout
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;} }
