Submitted by Nidhi, on January 22, 2022

Problem Solution:

In this program, we will create a two-dimensional array. Then we read and print the elements of the 2D array.

Program/Source Code:

The source code to read and print the two-dimensional array is given below. The given program is compiled and executed successfully.

```# Ruby program to read and print
# two-dimensional array

TwoDArr = Array.new(2){Array.new(2)}

printf "Enter elements of MATRIX:\n";
i = 0;
while (i < 2)
j = 0;
while (j < 2)
printf "ELEMENT [%d][%d]: ", i, j;
TwoDArr[i][j] =  gets.chomp.to_i;
j = j + 1;
end
i = i + 1;
end

printf "MATRIX:\n";
i = 0;
while (i < 2)
j = 0;
while (j < 2)
print TwoDArr[i][j]," ";
j = j + 1;
end
i = i + 1;
print "\n";
end
```

Output:

```Enter elements of MATRIX:
ELEMENT : 1
ELEMENT : 2
ELEMENT : 3
ELEMENT : 4
MATRIX:
1 2
3 4
```

Explanation:

In the above program, we created a two-dimensional array TwoDArr. Then we read the elements of the 2D array. After that, we printed the 2D array.
