Answer to Question #260517 in C++ for malika

Question

Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores = {10, 20, 30, 40}, then newScores = {20, 30, 40, 10}.

Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int oldScores[4]). See "How to Use zyBooks".

If the submitted code tries to access an invalid array element, such as newScores[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached".

#include <iostream>

using namespace std;

int main() {

  const int SCORES_SIZE = 4;

  int oldScores[SCORES_SIZE];

  int newScores[SCORES_SIZE];

  int i;

  for (i = 0; i < SCORES_SIZE; ++i) {

   cin >> oldScores[i];

  }

  /* Your solution goes here */

  for (i = 0; i < SCORES_SIZE; ++i) {

   cout << newScores[i] << " ";

  }

  cout << endl;

  return 0;

}

Source code

#include <iostream>


using namespace std;


int main() {


  const int SCORES_SIZE = 4;


  int oldScores[SCORES_SIZE];


  int newScores[SCORES_SIZE];


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


   cin >> oldScores[i];


  }


  /* Your solution goes here */
    int last=oldScores[0];
    for (int i=0;i<(SCORES_SIZE-1);i++)	
		newScores[i] = oldScores[i + 1];		
	
	newScores[SCORES_SIZE-1] = last;


  for (i = 0; i < SCORES_SIZE; ++i) {


   cout << newScores[i] << " ";


  }


  cout << endl;


  return 0;


}
