Question

8.6 Code Practice: Question 2

Answer 1

Answer:

In Java:

import java.util.*;

public class Main{

public static int sumArray(int []arr, int lent){

    int sum = 0;

    for(int i = 0; i<lent; i++){

     sum+=arr[i];

 }

 return sum; }

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 System.out.print("Number of elements: ");

 int lent = input.nextInt();

 Random rd = new Random();

 int [] intArray = new int[lent];

 for(int i = 0; i< lent; i++){

     intArray[i] = rd.nextInt(100)+1;

 }

 System.out.print("Total: "+sumArray(intArray,lent));

}

}

Explanation:

No previous code was provided; So, I had to write the program from scratch (in Java)

Also, the elements of the array were generated randomly

See attachment for program source file where I used comments for explanatory purpose.
