initializing 2d array c++ code example
Example 1: initialise 2d vector in c++
vector<vector<int> > vect{ { 1, 2, 3 },
{ 4, 5, 6 },
{ 7, 8, 9 } };
Example 2: get elements of 2d array c++
#include <array>
2 #include <iostream>
3
4 using namespace std;
5
6
7 const int ROWS = 2;
8 const int COLS = 3;
9
10 void printMatrix(array<array<int, COLS>, ROWS> matrix){
11
12 for (int row = 0; row < matrix.size(); ++row){
13
14 for (int col = 0; col < matrix[row].size(); ++col){
15 cout << matrix[row][col] << ' ';
16 }
17 cout << endl;
18 }
19 }
