Create a c++ program that declares, initializes, and outputs the values contained in a two-dimensional array

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int r_size,c_size;

cout<<"enter the number of row:";

// read the value of row

cin>>r_size;

cout<<"enter the number of column:";

// read the value of column

cin>>c_size;

// create a 2-d array

int arr[r_size][c_size];

// read the value of array

cout<<"enter the elements of array:"<<endl;

for(int x=0;x<r_size;x++)

{

for(int y=0;y<c_size;y++)

{

cin>>arr[x][y];

}

}

cout<<"elements of the array are:"<<endl;

// print the array

for(int a=0;a<r_size;a++)

{

for(int b=0;b<c_size;b++)

{

cout<<arr[a][b]<<" ";

}

cout<<endl;

}

return 0;

}

Explanation:

Here we have demonstrate a 2- dimensional array. In which, how to read the elements and how to print elements of array.Read the value of row and column from user.Create a 2-d array of size r_sizexc_size. then read the elements of array either row wise or column wise. Then print the elements.To print the elements, we can go either row wise or column.

Output:

enter the number of row:2

enter the number of column:3

enter the elements of array:

1 2 3

2 3 4

elements of the array are:

1 2 3

2 3 4
