Using 2D Arrays

Document preview thumbnail
Preview 1 out of 1 pages

The provided C++ code defines a program that initializes a 2D array (a table) with 3 rows and 2 columns containing integers. The `main` function initializes this array with specific values and then calls the `showValues` function to display the elements of the array. The `showValues` function takes a 2D array as an argument and uses nested loops to iterate through each element of the array, printing each value followed by a tab. After printing each row, it outputs a newline to separate the rows visually in the console. Overall, the functionality of this code is to display a 3x2 grid of integers in a formatted manner.

#include <iostream>
using namespace std;

const int ROW = 3;
const int COL = 2;

void showValues(int table[][COL]);


int main()
{
int table[ROW][COL] = {{2,4}, {6, 8}, {10, 12}};

showValues(table);
}

void showValues(int table[][COL])
{
for (int i = 0; i < ROW; i++)
{
for (int j = 0; j < COL; j++)
{
cout << table[i][j] << "\t";
}
cout << endl;
}
}
