Answer:
// here is code in C++ to demonstrate a 2-dimensional array.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int r,c;
cout<<"enter the number of row:";
// read the value of row
cin>>r;
cout<<"enter the number of column:";
// read the value of column
cin>>c;
// create a 2-d array
int arr[r][c];
// read the value of array
cout<<"enter the elements of array:"<<endl;
for(int a=0;a<r;a++)
{
for(int b=0;b<c;b++)
{
cin>>arr[a][b];
}
}
cout<<"elements of the array are:"<<endl;
// print the array
for(int a=0;a<r;a++)
{
for(int b=0;b<c;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 rxc. 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:3
enter the number of column:3
enter the elements of array:
1 2 3
9 8 7
2 4 6
elements of the array are:
1 2 3
9 8 7
2 4 6
