Write a piece of code that constructs a jagged two-dimensional array of integers named jagged with five rows and an increasing n
Ksivusya [100]

Answer:

Explanation:

The following code is written in Java and it uses nested for loops to create the array elements and then the same for loops in order to print out the elements in a pyramid-like format as shown in the question. The output of the code can be seen in the attached image below.

class Brainly {

   public static void main(String[] args) {

       int jagged[][] = new int[5][];

       int element = 1;

       for(int i=0; i<5; i++){

           jagged[i] = new int[i+1]; // creating number of columns based on current value

           for(int x = 0; x < jagged[i].length; x++) {

               jagged[i][x] = element;

               element += 1;

           }

       }

       System.out.println("Jagged Array elements are: ");

       for ( int[] x : jagged) {

           for (int y : x) {

               System.out.print(y + " ");

           }

           System.out.println(' ');

       }

       }

Answer:

The Matlab code is as given in the explanation, paste the code in the new script file, save it and run.

Explanation:

The code is as follows

Code:

<em>%% Initialization of the code</em>

<em>% The code takes an array of six AIS scores of the form [AIS1 AIS2 AIS3</em>

<em>% AIS4 AIS5 AIS6] of order 1x6.</em>

<em>AIS=input('Please enter the AIS array of the form [AIS1 AIS2 AIS3 AIS4 AIS5 AIS6]');%taking input of the array</em>

<em>AISs=sort(AIS,'descend');%sorting the array in the descending order</em>

<em>iss=(AISs(1,1)^2)+(AISs(1,2)^2)+(AISs(1,3)^2);%Calculating the ISS</em>

<em>disp(['The injury severity score (ISS) for the entered array is ', num2str(iss)])%Displaying the output</em>

Output:

<u><em>Please enter the AIS array of the form [AIS1 AIS2 AIS3 AIS4 AIS5 AIS6][3 0 4 5 3 0];</em></u>

<u><em>The injury severity score (ISS) for the entered array is 50</em></u>
