Question

need help debugging. This is where my errors start.
return sum/howManyPlayers;
}
void displayBelowAverage(string names[], int scores[]);
{
double average =0.0;
average = calculateAverageScore(scores,howManyPlayers);
for (int k = 0; k < howManyPlayers; k++)
{
if (scores[k] < average)
{
cout << names[k] << "\t\t" << scores[k] << endl;
}
}
return;
}

Answer 1

a) attach the cpp files next time
b) we need the errors

Answer 2

first problems I see with your code:

your includes have semicolons at the end. they're of the format #include <cmath>

Answer 3

main function must return an int. the main method follows the pattern
int main() {
return 0;
}

line 50: there are 3 minuses in your decrement operation.

line 73: return sum/howManyPlayers is dividing a double by an int ARRAY.

Answer 4

Also, at the top left of your keyboard there's this symbol ` use it to make code by typing it three times to begin a block and end a block like this:

```
public static int number =8;
prettyColors("Super Cool Yo");
```
Yeah.

Answer 5

```
#include <iostream>
#include <string>

//Prototype all functions.
double calculateAverageScore(int scores[],int numberOfPlayers);
void displayPlayerData(std::string names[], int scores[],int numberOfPlayers);
void displayBelowAverage(std::string names[], int scores[], int numberOfPlayers);
int inputData(std::string names[], int scores[]);

int main()
{
std::string playerNames[100];
int scores[100];
int numberOfPlayers = inputData(playerNames, scores);

std::cout << "\n\nListing of players and their scores\n";
displayPlayerData(playerNames, scores,numberOfPlayers);

std::cout << "\nAverage Score: " << calculateAverageScore(scores,numberOfPlayers) << "\n\n";

std::cout << "\n\nListing of players with below avg scores\n";
displayBelowAverage(playerNames, scores, numberOfPlayers);

return 0;
}

double calculateAverageScore(int scores[],int numberOfPlayers) {
double sum = 0.0;
for (int i=0;i<numberOfPlayers;i++)
sum += scores[i];

return (sum/numberOfPlayers);
}

void displayPlayerData(std::string names[],int scores[],int numberOfPlayers) {
for(int i=0;i<numberOfPlayers;++i)
std::cout << '\t' << names[i] << '\t' << scores[i] << std::endl;
}

void displayBelowAverage(std::string names[],int scores[],int numberOfPlayers) {
double average = calculateAverageScore(scores,numberOfPlayers);
for (int i=0;i<numberOfPlayers;i++)
{
if(scores[i] < average)
std::cout << '\t' << names[i] << '\t' << scores[i] << std::endl;
}
}

int inputData(std::string names[], int scores[]) {
int numberOfPlayers = 0;
std::cout << "q to quit\n\n";
std::cout << "enter name\n";
std::cin >> names[0];

if(names[0] == "q") return 0;

std::cout << "enter score for " << names[0] << "\n";
std::cin >> scores[0];


while(numberOfPlayers<100 && names[numberOfPlayers] != "q") {
numberOfPlayers++;
std::cout << "Enter player name (Q to quit): ";

std::cin >> names[numberOfPlayers];

if(names[numberOfPlayers]=="q") {
//numberOfPlayers--; unnecessary because we increment at the start of the while loop
break;
}
else {
std::cout << "Enter score for " << names[numberOfPlayers] << ": ";
std::cin >> scores[numberOfPlayers];
}
}
return numberOfPlayers;
}
```

I could have just written the pseudocode but meh. comment/refactor as you will. it's mostly your code anyways

example of it running:
```
q to quit

enter name
harry
enter score for harry
38
Enter player name (Q to quit): mark
Enter score for mark: 86
Enter player name (Q to quit): q


Listing of players and their scores
harry 38
mark 86

Average Score: 62


Listing of players with below avg scores
harry 38
