Different Ways to Initialize a vector in C++
In this article we will discuss different ways to initialize a std::vector in C++. Initializing std::vector elements with same value std::vector<int> vec_1(5, 10); It will create a vector of 5 element and initialize  each element is initialized to 10. Advertisements Initializing std::vector elements with passed argument list std::vector<int> vec_2 = {10,20,30,40,50}; It will create a vector of 5 …
5 Different ways to Initialize a vector in c++
In this article we will discuss different ways to initialize a vector in C++. Creating a vector object without any initialization will create an empty vector with no elements i.e. Advertisements std::vector<int> vecOfInts; But we generally want to initialize a vector with huge values and calling push_back() that many times to add element in vector is not an …
Different ways to Initialize a list in C++
In this article we will discuss the different ways to initialize a std::list in C++. std::list provides various overloaded constructors for creation and initialization of list. Let’s see different ways to create & initialize a std::list in C++ i.e. Advertisements Creating an Empty List in C++ std::list has a default constructor that will create an empty …
Different Ways to initialize an unordered_map
In this article we will discuss the different ways to initialize an unordered_map. unordered_map provides different overloaded constructors. We will use some of them to initialize an unordered_set in 3 different ways i.e. Initializing through an initializer_list Initializing through a iterable range. Initializing through an another map. Lets see them in detail, Advertisements Initializing an unordered_map …
Different ways to insert elements in an unordered_map
In this article we will discuss the different ways to insert elements in an unordered_map. Unordered_map provides different overloaded versions of insert() member function to insert key value pairs in an unordered_map. Lets discuss them one by one. Advertisements Inserting multiple elements in unordered_map through an initializer_list unordered_map provides an overloaded version of insert that …

Overriding a method with different return type in Java
In this article we will discuss how to override a method in Java with different return type. The basic rule for overriding a method in Java is that the new overriding method in derived class should have same signature as of Base class’s method. But there is on exception to this rule i.e. Advertisements Overriding method …

Let’s discuss them one by one, Advertisements Inserting a Single element in Set and checking the result Set is an associative container and contains only unique elements, …
Different ways to iterate over a set in C++
In this article we will discuss different ways to iterate over a set in C++. Let’s create a set of strings i.e. Advertisements // Set of strings std::set<std::string> setOfStr = { “jjj”, “khj”, “bca”, “aaa”, “ddd” }; Now let’s iterate over it and print the contents on screen using different methods i.e. Iterating over a …
C++ : Different Ways to iterate over a List of objects
In this article we will discuss different ways to iterate through std::list of objects. Suppose we have a struct Player that contains id and name i.e. Advertisements struct Player { int id; std::string name; Player(int playerId, std::string playerName) : id(playerId), name(playerName) { } }; Lets create a list Player objects i.e. std::list<Player> listofPlayers = { …
