C++, Visual Studio
Hello, i need help with code.
1) removing "#include
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
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;
