Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores = {10, 20, 3

0, 40}, then newScores = {20, 30, 40, 10}. Note: These activities may test code with different test values. This activity will perform two tests, the first with a 4-element array (newScores = {10, 20, 30, 40}), the second with a 1-element array (newScores = {199}).
public class StudentScores {
public static void main (String [] args) {
final int SCORES_SIZE = 4;
int[] oldScores = new int[SCORES_SIZE];
int[] newScores = new int[SCORES_SIZE];
int i = 0;

oldScores[0] = 10;
oldScores[1] = 20;
oldScores[2] = 30;
oldScores[3] = 40;

/* Your solution goes here */

for (i = 0; i < SCORES_SIZE; ++i) {
System.out.print(newScores[i] + " ");
}
System.out.println();

return;
}

Answer:

The appropriate code for this query can be expressed as:

Code:

int lastVector = newScores.size() - 1; //define variable lastVector to store updated size of newScores.

newScores = oldScores; //assigning value.

for (i = 0; i < SCORES_SIZE - 1; i++) //initialize loop.

{

newScores.at(i) = newScores.at(i + 1); //store value in newScores.

}

newScores.at(lastVector) = oldScores.at(0); //place first element at the end.

Explanation:

The provided C++ program contains two defined vector arrays, named "oldScores and newScores". The oldScores array contains elements "10, 20, 30, 40".
The snippet above shifts the first element from oldScores to the last position in newScores. To achieve this, an integer variable "lastVector" is created.
This variable retains the size of newScores, and as such, all elements from oldScores are assigned to newScores. The loop involves using the at function to remove the first array element and append it to the end.
Lastly, a separate loop is used to print the elements of the newScores array.
