In this tutorial, we will be discussing a program to understand the various merge operations using STL in C++.The merge() function is used to merge two sorted containers in a way that the new container is also sorted. Further includes() is used to check if the elements from first container ... Read More

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 ... Read More

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 ... Read More

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(){ ... Read More

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 ... Read More

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 ... Read More

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);   ... Read More

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 ...
