Question

Write a loop that sets new scores to old scores shifted once left, with element 0 copied to the end. ex: if old scores = {10, 20, 30, 40}, then newscores = {20, 30, 40, 10}.

Answer 1

For the given problem, define the size equal to 4 since four scores are given. Now, create two arrays: one for storing old score values and second for storing new score values. After this, assign old scores in an array and then create a loop that will shift the old score from second element until the one less than the size . Now, display the old scores and new scores as shown in output.

Further explanation:

Code:

The Java code to set the new scores from given old scores is as given below:

//Define the StudentScore class

public class StudentScores

{

//main method

public static void main(String[] args)

{

//Define final variable

final int SCORES_SIZE=4;

//Create two array

int[] oldScores = new int[SCORES_SIZE];

int[] newScores = new int[SCORES_SIZE];

//Declare a variable

int i = 0;

//Assign values to array

oldScores[0]=10;

oldScores[1]=20;

oldScores[2]=30;

oldScores[3]=40;

/*Your solution goes here*/

int firstOldScore=oldScores[0];

//Run for loop to shift the old score from second element until the one less than the size

for(int index=0;index<SCORES_SIZE-1;index++)

{

//shift oldScores to newScores

newScores[index]=oldScores[index+1];

}

newScores[SCORES_SIZE-1]=firstOldScore;

System.out.println("oldScores:");

for(i=0;i<SCORES_SIZE;++i)

{

// Display the oldScores

System.out.print(oldScores[i]+" ");

}

System.out.println();

// Print the new scores

System.out.println("newScores:");

for (i=0;i<SCORES_SIZE;++i)

{

//Display newScores

System.out.print(newScores[i] + " ");

}

System.out.println();

return;

}

}

Output:

oldScores:

10 20 30 40

newScores:

20 30 40 10

Answer 2

#include <iostream>
using namespace std;

int main() {
   const int SCORES_SIZE = 4;
   int oldScores[SCORES_SIZE];
   int newScores[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) {
      cout << newScores[i] <<" ";
   }
   cout << endl;

   return 0;
