The Standard Template Library (STL) is a software library for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms, containers, functions, and iterators. Note that the term "STL" or "Standard Template Library" does not show up anywhere in the ISO 14882 C++ standard. So referring to the C++ standard library as STL is wrong, ie, STL and C++ Standard Library are 2 different things with the former being the subset of the latter.The STL consists ofContainersThe STL contains sequence containers and associative containers. Containers are objects that store data. The ... Read More
Use the animation-timing-function property, with the ease-out value to set animation with a slow end with CSSExampleLive Demo div { width: 150px; height: 200px; position: relative; background-color: #808000; animation-name: myanim; animation-duration: 2s; animation-direction: alternate-reverse; animation-iteration-count: 3; } @keyframes myanim { from {left: 100px;} to {left: 200px;} } #demo {animation-timing-function: ease-out;} ease-out effect
Access the buf.buffer property directly to convert a binary NodeJS Buffer to JavaScript ArrayBuffer. The write through the original Buffer instance writes the ArrayBufferView.Keep in mind that the instances of Buffer are also instances of Uint8Array in node.js 4.x and higher versions.ExampleYou can try the following code snippet to convert a NodeJS buffer to JavaScript ArrayBuffer −function toArrayBuffer(myBuf) { var myBuffer = new ArrayBuffer(myBuf.length); var res = new Uint8Array(myBuffer); for (var i = 0; i < myBuf.length; ++i) { res[i] = myBuf[i]; } return myBuffer; }
Use the animation-timing-function property, with the linear value to set animation with the same speed from start to end with CSSExampleLive 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;} } #demo {animation-timing-function: linear;} linear effect
You can use the itoa function from C to convert an int to string. example#include int main() { int a = 10; char *intStr = itoa(a); string str = string(intStr); cout
The explicit keyword in C++ is used to mark constructors to not implicitly convert types. For example, if you have a class Foo −class Foo { public: Foo(int n); // allocates n bytes to the Foo object Foo(const char *p); // initialize object with char *p };Now if you tryFoo mystring = 'x';The char 'x' is implicitly converted to int and then will call the Foo(int) constructor. But this is not what was intended. So to prevent such conditions and make the code less error-prone, define the constructor as explicit −Example class Foo { public: ... Read More
A process dumps core when it is terminated by the operating system due to a fault in the program. The most typical reason this occurs is that the program accessed an invalid pointer value like NULL or some value out of its memory area. As part of that process, the operating system tries to write our information to a file to allow us to analyze what happened.This core can be used as follows to diagnose and debug our program −The core is dumped to the /proc/sys/kernel directory by default. To debug a core, the program must be compiled with the ... Read More
Use the animation-direction property to set whether an animation should be played forwards, backward or in alternate cycles:ExampleLive Demo div { width: 150px; height: 200px; background-color: yellow; animation-name: myanim; animation-duration: 2s; animation-direction: reverse; } @keyframes myanim { from { background-color: green; } to { background-color: blue; } }
