In this tutorial, we will be discussing a program to understand map equal_range in C++ STL.This function returns a pair of iterators that bounds the range of the container in which the key equivalent to the given parameter resides.Example Live Demo#include using namespace std; int main() {    //initializing container    map mp;    mp.insert({ 4, 30 });    mp.insert({ 1, 40 });    mp.insert({ 6, 60 });    pair       it;    it = mp.equal_range(1);    cout

In this tutorial, we will be discussing a program to get maximum of all subarrays of size k using set in C++ STL.For this we will be provided with a array of size N and integer K. Our task is to get the maximum element in each K elements, add them up and print it out.Example Live Demo#include using namespace std; //returning sum of maximum elements int maxOfSubarrays(int arr[], int n, int k){    set q;    set::reverse_iterator it;    //inserting elements    for (int i = 0; i < k; i++) {       q.insert(pair(arr[i], i));    } ...

In this tutorial, we will be discussing a program to create a menu driven program for a simple calculator.This program will give user the ability to choose among the following mathematical operations − addition, subtraction, multiplication, division, HCF and LCM.Example Live Demo#include using namespace std; //displaying the menu void menu(){    cout

In this tutorial, we will be discussing a program to understand Multiset in C++ STL (Standard Template Library).Multiset are associative containers much similar to sets. The one difference multiset holds is they can even contain duplicate values.Example Live Demo#include #include #include using namespace std; int main(){    multiset gquiz1;    //inserting values    gquiz1.insert(40);    gquiz1.insert(30);    gquiz1.insert(60);    gquiz1.insert(20);    gquiz1.insert(50);    gquiz1.insert(50);    gquiz1.insert(10);    multiset :: iterator itr;    cout

In this tutorial, we will be discussing a program to understand negative_binomial_distribution in C++.This function follows the negative Binomial discrete distribution and produces integers according to this random distribution.Example Live Demo#include using namespace std; int main() {    //setting number of experiments    const int exps = 10000;    const int numberstars = 100;    default_random_engine generator;    negative_binomial_distribution distribution(4, 0.5);    int p[10] = {};    for (int i = 0; i < exps; ++i) {       int counting = distribution(generator);       if (counting < 10)          ++p[counting];    }    cout

In this tutorial, we will be discussing a program to understand multiset max_size() in C++ STL.The function max_size() returns the maximum number of elements a given container can hold.Example Live Demo#include using namespace std; int main(){    multiset s;    s.insert(10);    s.insert(13);    s.insert(13);    s.insert(25);    s.insert(24);    cout

In this tutorial, we will be discussing a program to understand multiset size() in C++ STL.The function size() returns the number of elements present into a given container.Example Live Demo#include using namespace std; int main(){    multiset s;    s.insert(10);    s.insert(13);    cout

In this tutorial, we will be discussing a program to understand order_of_key() in C++.The function order_of_key() takes in a key and returns the number of elements which are less than the key provided as parameter in an ordered set.Example Live Demo#include using namespace std; #include #include #include #include using namespace __gnu_pbds; using namespace std; //initializing ordered set typedef tree    ordered_set; int main(){    ordered_set mySet;    mySet.insert(5);    mySet.insert(2);    mySet.insert(6);    mySet.insert(4);       cout

The below lines of code can be used, wherein UTF-8 input is expected.$chr_map = array(    // Windows codepage 1252    "\xC2\x82" => "'", // U+0082⇒U+201A single low-9 quotation mark    "\xC2\x84" => '"', // U+0084⇒U+201E double low-9 quotation mark    "\xC2\x8B" => "'", // U+008B⇒U+2039 single left-pointing angle quotation mark    "\xC2\x91" => "'", // U+0091⇒U+2018 left single quotation mark    "\xC2\x92" => "'", // U+0092⇒U+2019 right single quotation mark    "\xC2\x93" => '"', // U+0093⇒U+201C left double quotation mark    "\xC2\x94" => '"', // U+0094⇒U+201D right double quotation mark    "\xC2\x9B" => "'", // U+009B⇒U+203A single right-pointing angle ...

A PHP reference is an alias, that allows two different variables to write it to the same value. In PHP version 5, an object variable doesn't contain the object itself as its value. It holds an object identifier that allows object accessors to find the actual object.When an object is sent by an argument, returned or assigned to a different variable, these different variables are not aliases. They contain a copy of the identifier, that points to the same object.Example$my_var = new class_name; echo $my_var->get_class_name(5)->value; $my_var->test(); echo $my_var->get_class_name(5)->value;OutputThis will produce the following output −class_name #5This isn't "pass by reference".
