Vector in C++ STL - GeeksforGeeks

C++ vector is a dynamic array that stores collection of elements same type in contiguous memory. It has the ability to resize itself automatically when an element is inserted or deleted. Create a Vector. Before creating a vector, we must know that a vector is defined as the std::vector class template in the < vector > header file.. C++

c++ - Passing vectors by reference - Stack Overflow

Another option is to pass around iterators instead of containers. This is the approach the standard library takes in <algorithm>.They are slightly more verbose at the calling site, but they have the advantage that they work for parts of a collection as well as complete collections and decouples the algorithm from the container.

Vector insert() in C++ STL - GeeksforGeeks

In C++, the vector data() is a built-in function used to access the internal array used by the vector to store its elements. In this article, we will learn about vector data() in C++.Let’s take a look at an example that illustrates the vector data() method:C++#include <bits/stdc++.h> using nam

Sorting a Vector in C++ – TheLinuxCode

A vector in C++ is a sequence container that provides dynamic array functionality. Unlike traditional arrays, vectors can resize themselves automatically when elements are inserted or deleted. They store elements in contiguous memory locations, which means they offer the performance benefits of arrays while providing additional flexibility. ...

C++ developments - C++ Forum - C++ Users

Yes I use std::tuple. I like it, but its not as convenient. Don't like the "std::get<>" syntax much. You can't add more elements to it easily as you could something like a vector. I was thinking similar to a Python array which could easily hold and deal with multiple types. I don't think this kind of thing will ever come to C++ though.

2D Vector in C++ - GeeksforGeeks

Inserting Elements in a 2D Vector. In 2d vectors, there are two types of insertion: Inserting a new row. Insert a value in an existing row. These can be inserted at any given position using vector insert() and at the end using vector push_back(). As vector can dynamically grow, each row can have different size like Java's jagged arrays.
