2. 2D Vector In C++ With User Defined Size - GeeksforGeeks

   www.geeksforgeeks.org/2d-vector-in-cpp-with-user-defined-size

   A 2D vector is a vector of the vector. Like 2D arrays, we can declare and assign values to a 2D vector! Assuming you are familiar with a normal vector in C++, with the help of an example we demonstrate how a 2D vector differs from a normal vector below:

3. 2D Vectors in C++ - A Practical Guide 2D Vectors - DigitalOcean

   www.digitalocean.com/community/tutorials/2d-vectors-in-c-plus-plus

   Also referred to as vector of vectors, 2D vectors in C++ form the basis of creating matrices, tables, or any other structures, dynamically. Before arriving on the topic of 2D vectors in C++, it is advised to go through the tutorial of using single-dimensional vectors in C++ .

4. c++ - Multi-dimensional vector - Stack Overflow

   stackoverflow.com/questions/823562

   Just use the following method to use 2-D vector. int rows, columns; // . . . vector < vector < int > > Matrix(rows, vector< int >(columns,0)); Or vector < vector < int > > Matrix; Matrix.assign(rows, vector < int >(columns, 0)); // Do your stuff here...

5. c++ - Initializing a two-dimensional std::vector - Stack Overflow

   stackoverflow.com/questions/17663186

   std::vector<std::vector<int> > v (A_NUMBER, std::vector <int> (OTHER_NUMBER, DEFAULT_VALUE)) Here, the vector 'v' can be visualised as a two dimensional array, with 'A_NUMBER' of rows, with 'OTHER_NUMBER' of columns with their initial value set to 'DEFAULT_VALUE'.

    What is a 2D vector? Vector of Vectors is a 2D vector, it is nothing but a dynamic array in C++ means it has the ability to resize itself automatically, whenever we add or remove elements in it. Like a 2D array, it consists of rows and columns where each row is a different type of vector.
