Scala program to add two integer arrays

Program/Source Code:

The source code to add two integer arrays is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to add two integer arrays

object Sample {
  def main(args: Array[String]) {
    var IntArray1 = Array(10, 20, 30, 40, 50)
    var IntArray2 = Array(11, 21, 31, 41, 51)
    var IntArray3 = new Array[Int](5)
    var i: Int = 0

    println("Elements of IntArray1: ");
    i = 0;
    while (i < 5) {
      printf("%d ", IntArray1(i));
      i = i + 1;
    }
    println()

    println("\nElements of IntArray2: ");
    i = 0;
    while (i < 5) {
      printf("%d ", IntArray2(i));
      i = i + 1;
    }
    println()

    i = 0;
    while (i < 5) {
      IntArray3(i) = IntArray1(i) + IntArray2(i);
      i = i + 1;
    }

    println("\nAddition of IntArray1 and IntArray2: ");
    i = 0;
    while (i < 5) {
      printf("%d ", IntArray3(i));
      i = i + 1;
    }
    println()
  }
}

Output:

Elements of IntArray1: 
10 20 30 40 50 

Elements of IntArray2: 
11 21 31 41 51 

Addition of IntArray1 and IntArray2: 
21 41 61 81 101

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 two arrays IntArray1, IntArray2.  Each array contains 5 integer items. Then we added elements of IntArray1 with IntArray2 and assigned the result into IntArray3. After that, we printed all arrays on the console screen.
