## Scala – Printing the Transpose Matrix

Here, we will create a 2X2 matrix using a two-dimensional array and then we will read elements of the matrix and then print the transpose of the matrix on the console screen.

## Scala code to print the transpose of matrix

The source code to print the transpose of MATRIX is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

```// Scala program to print the transpose of MATRIX

object Sample {
def main(args: Array[String]) {
var TwoDArr = Array.ofDim[Int](2, 2)
var i: Int = 0
var j: Int = 0

printf("Enter elements of MATRIX:\n")
i = 0;
while (i < 2) {
j = 0;
while (j < 2) {
printf("ELEMENT(%d)(%d): ", i, j);
j = j + 1;
}
i = i + 1;
}

printf("MATRIX:\n")
i = 0;
while (i < 2) {
j = 0;
while (j < 2) {
printf("%d ", TwoDArr(i)(j));
j = j + 1;
}
i = i + 1;
println();
}

printf("MATRIX TRANSPOSE:\n")
i = 0;
while (i < 2) {
j = 0;
while (j < 2) {
printf("%d ", TwoDArr(j)(i));
j = j + 1;
}
i = i + 1;
println();
}
}
}
```

## Output

```Enter elements of MATRIX:
ELEMENT(0)(0): 10
ELEMENT(0)(1): 20
ELEMENT(1)(0): 30
ELEMENT(1)(1): 40
MATRIX:
10 20
30 40
MATRIX TRANSPOSE:
10 30
20 40
```

## Explanation

In the above program, we used an object-oriented approach to create the program. We created an object Sample, and we defined main() function. The main() function is the entry point for the program.

In the main() function, we created a 2X2 matrix using a two-dimensional array, and then we read the elements of the matrix from the user. Then print the elements of the matrix and also print its transpose on the console screen.
