C++, Visual Studio

Hello, i need help with code.

1) removing "#include " and ALL of the "stoi" in the code.

2) Average won't calculate correctly. This is what is shown when calculating the average compared to what it's supposed to calculate:

RESTRICTIONS:

No global variables

No labels or go-to statements

No infinite loops

No break statements

This is the code:

#include

#include

#include

#include //CHANGE / REMOVE!!

using namespace std;

// Function Prototypes

double calcAverage(int testScore[], int& sum, double& average);

void validateUserInput(string& userEntry);

void determineGrade(int testScore[], char grade[]);

void bubbleSort(int testScore[]);

void displayTestScores(int testScore[], char grade[], int sum, double average);

int main()

{

// declare Array to hold test scores

int testScore[5];

// declare Array to hold grades

char grade[5];

// Initializations and declarations

string userEntry;

int i = 0;

double average;

int sum;

while (i

{

// Lets the user input each test score one by one

cout

getline(cin, userEntry);

validateUserInput(userEntry); // Calls validateUserInput function

int userEntryInt = atoi(userEntry.c_str()); // CHANGE / REMOVE!!!

testScore[i] = userEntryInt; // Scores each score in an array called testScore

i++;

}

bubbleSort(testScore); // Calls bubbleSort function

calcAverage(testScore, sum, average); // Calls calcAverage function

determineGrade(testScore, grade); // Calls determineGrade function

displayTestScores(testScore, grade, sum, average); // Calls displayTestScores function

system("pause");

return 0;

}

double calcAverage(int testScore[], int& sum, double& average)

{

for (int i = 0; i

{

// Adds all the test scores

sum = sum + testScore[i];

}

average = sum / 5;
