Something wrong with the program - Modify the program to allow the user to enter

Question

Something wrong with the program - Modify the program to allow the user to enter name-score pairs. For each student taking a test, the user types the student's name followed by the student's integer test score. Modify the sorting function so it takes an array holding the student names and an array holding the student test scores. When the sorted list of scores is displayed, each student's name should be displayed along with his or her socre. In stepping through the arrays, use pointers rather than array subscripts.

float Average(int*score, int n){
   int i;
   float avg = 0.0;
   for (i = 1; i < n; i++){
       avg += score[i];
   }
   avg = avg / n;
   return avg;
}

Explanation / Answer

Bellow is the Modified code:

#include<iostream>
#include<string>
using namespace std;
// function
float Average(int *scores, int number);
void SortTestScores(int*scores, string *Names, int n);
int main()
{
//variable deslaration
int *testScores = new int[50];
string *Names = new string[50];
float averageScore;
int number, i;
cout << "Enter number of test Scores :";
cin >> number;
for (i = 0; i < number; i++)
{
cout << "Enter the names : ";
cin >> Names[i];
cout << "Enter test Scores : ";
cin >> testScores[i];
}
SortTestScores(testScores, Names, number);
cout << "Name " << "TestScore" << endl;
for (i = 0; i < number; i++)
{   
cout << Names[i] << " ";
cout << testScores[i] << endl;
  
}
averageScore = Average(testScores, number);
cout << "Average testScore is:" << averageScore << endl;
system("pause");
  
}
void SortTestScores(int *scores, string *Names, int number)
{
int temp;
string tempname;
int i, j;
for (i = 1; i < number; i++){
for (j = 0; j < i; j++)
{
if (scores[j]>scores[j + 1]){
temp = scores[j];
scores[j] = scores[j + 1];
scores[j + 1] = temp;
tempname = Names[j];
Names[j] = Names[j + 1];
Names[j + 1] = tempname;
}
}
}
}
float Average(int*score, int n){
int i;
float avg = 0.0;
for (i = 0; i < n; i++){
avg += score[i];
}
avg = avg / n;
return avg;
}

Out Put:

Enter number of test Scores :4

Enter the names : Naidu

Enter test Scores : 10

Enter the names : Rajev

Enter test Scores : 30

Enter the names : chandu

Enter test Scores : 5

Enter the names : deva

Enter test Scores : 25

Name TestScore

chandu 5

Naidu 10

deva 25

Rajev 30

Average testScore is:17.5
