Arrays in C++

[kenny24]

Hi everyone,

I am trying to write a program that inputs 7 scores into an array and then drops the lowest score and averages the remaining scores. However, I am having trouble getting the program to run, I thought I had all the code I needed but visual studio won't run my program. Any help is greatly appreciated, thank you. Below is my code that I have written so far.

#include <iostream>
#include <iomanip>
using namespace std;

//function prototypes
double GetLowest(const double[], int);
void GetScores(double[], int);
double GetTotal(const double[], int);

int main()
{
	const int SIZE = 7;
	double TestScores[SIZE],
		total,
		Lowestscore,
		average;

	cout << fixed << showpoint << setprecision(1);

	GetScores(TestScores, SIZE);

	total = GetTotal(TestScores, SIZE);

	Lowestscore = GetLowest(TestScores, SIZE);

	total -= Lowestscore;

	average = total / (SIZE - 1);

	cout << "The average of the test scores with the lowest score excluded is " << average << ".\n";

	return 0;
}
void GradeArray(double score[], int size)
{
	int count;
    //get the 7 test scores
	for (count=0; count <= size; count++)
	{
		cout << "Enter test score number " << (count + 1) << ": ";
		cin >> score[count];
	}
}
double GetTotal(const double array[], int size)
{
	double total = 0;

	for (int count = 0; count < size; count++)
		total += array[count];
	return total;
}
double GetLowest(const double array[], int size)
{
	double lowest;

	lowest = array[0];

	for (int count = 1; count < size; count++)
		lowest = array[count];
	return lowest;
}

void GetScores(double[], int);

Function definition is unavailable.

void GradeArray(double score[], int size)

Looks like this is GetScores function.

@12 const int SIZE = 7;
@13 double TestScores[SIZE],
@34 void GetScores(double score[], int size)
@38 for (count=0; count <= size; count++)
@49 total += array[count];

The loop index range is 0-7 which means memory access of array[0]....array[7]. But array is of size 6 elements array[0]...array[6]. The for loop should be

for (count=0; count < size; count++)

Thanks for the help!
And the program is giving me an average of 80.7 instead of 82.66667. Which is what I need, I believe it may be dropping my last entered score instead of my lowest score. But I'm really not sure.

#include <iostream>
#include <iomanip>
using namespace std;

//function prototypes
double GetLowest(const double[], int);
void GetScores(double[], int);
double GetTotal(const double[], int);

int main()
{
	const int SIZE = 7;
	double TestScores[SIZE],
		total,
		Lowestscore,
		average;

	cout << fixed << showpoint << setprecision(1);

	GetScores(TestScores, SIZE);

	total = GetTotal(TestScores, SIZE);

	Lowestscore = GetLowest(TestScores, SIZE);

	total -= Lowestscore;

	average = total / (SIZE - 1);

	cout << "The average of the test scores with the lowest score excluded is " << average << ".\n";

	return 0;
}
void GetScores(double score[], int size)
{
	int count;
    //get the 7 test scores
	for (count=0; count < size; count++)
	{
		cout << "Enter test score number " << (count + 1) << ": ";
		cin >> score[count];
	}
}
double GetTotal(const double array[], int size)
{
	double total = 0;

	for (int count = 0; count < size; count++)
		total += array[count];
	return total;
}
double GetLowest(const double array[], int size)
{
	double lowest;

	lowest = array[0];

	for (int count = 1; count < size; count++)
		lowest = array[count];
	return lowest;
}

@28 average = total / (SIZE - 1);

This should be just SIZE. Like:

average = total / SIZE;

Also, the function "GetLowest" is wrong. it doesn't find the lowest,but just assign the last iteration within the loop.
