trying to calculate and display average ...

trying to calculate and display average of the four highest scores. NEED HELP!!

#include "stdafx.h"
#include <iostream>
using namespace std;

void getScore(int &, int &, int &, int &, int &);
void calcAverage(double, double, double, double, double);
int findLowest();

int main()
{
int s1, s2, s3, s4, s5;

cout << "I am staring in function main.\n";

getScore(s1, s2, s3, s4, s5);
cout << "Now back in main. The 5 test score are: " << endl;
cout << s1 << endl << s2 << endl << s3 << endl << s4 << endl << s5 << endl;

cout << "Now back in main." << endl;
cout << "The average of the 4 highest test scores is: ";
calcAverage(s1, s2, s3, s4, s5);
cout << s1 << endl << s2 << endl << s3 << endl << s4 << endl << s5 << endl;
return 0;
}

void getScore(int &s1, int &s2, int &s3, int &s4, int &s5)
{
cout << "Enter 5 test scores: ";
cin >> s1 >> s2 >> s3 >> s4 >> s5;

// Input Validation// while (s1 < 0 || s1 > 100 && s2 < 0 || s2 > 100 && s3 < 0 || s3 > 100 &&
s4 < 0 || s4 > 100 && s5 < 0 || s5 > 100)
{
cout << "Invaild value entered !!" << endl;
cout << "Please enter a value between 0 through 100: ";
cin >> s1 >> s2 >> s3 >> s4 >> s5;
}

}

void calcAverage(double s1, double s2, double s3, double s4, double s5)
{

cout << (s1 + s2 + s3 + s4 + s5) / 4 << endl;

}

Hi jrock,
I think U should write the problem statement.

Gud to see the code. But U can make it better If u would have used the "insert code" button while posting.

AnyWay I think If U r wondering why it is not providing the right output the problem lies below:


cout << (s1 + s2 + s3 + s4 + s5) / 4 << endl;

U r taking sum of five values, where as dividing it by 4 to get the Average of 5 numbers !!!

Please post questions in one forum only! There are links to a couple of guidance articles at the bottom of this, please read them.

jrock wrote (in other forum):
| Write a program that calculates the average of a group of test scores,
| where the lowest score in the group is dropped. It should use the
| following functions:
|
| a.) voidgetScore() should ask the user for a test score, store it in a
| reference parameter variable, and validate it. This function should be
| called by main once for each of the five scores to be entered.
|
| b.) voidcalcAverage() should calculate and display the average of the
| four highest scores. This function should be called just once by main, and
| should be passed the five scores.
|
| c.) int findLowest() should find and return the lowest of the five scores
| passed to it. It should be called by calcAverage, who uses the function to
| determine which of the five scores to drop.
|
| // Input validation // DO NOT ACCEPT TEST SCORES LOWER THAN 0 OR
| HIGHER THAN 100

Part a, says to use the function void getScore() to get a score...

1 2 3 4

void getScore(int& val)
{
...
}

Part b, You would have to do somthing along the line of

1 2 3 4

sum equals the sum of values 1 through 5
sum equals sum minus findLowest()
average = sum divided by 4
display average

part c, you would have somthing like

1 2 3 4 5

lowest value equals 100
if value 1 is less than lowest then lowest equals value 1
if value 2 is less than lowest then lowest equals value 2
...
Return lowest

First, let it be known, mainly to Grey Wolf, being an ass to someone is not the most optimized way to solve a problem.

Next, on to helping jrock. Multiple functions isn't necessary for such a small task, you could just stick inside of main.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

// four highest scores average.cpp : main project file.

#include "stdafx.h"
#include <iostream>

using namespace std;
using namespace System;

int main() 
{
	int scores[5], temp;
	do {
		cout << "Please enter a score: ";
		cin >> scores[0];
	} while(scores[0] < 0 || scores[0] > 100);

	for(int i = 1; i < 5; i++){
		do {
		cout << "\n\nPlease enter a score: ";
		cin >> scores[i];
		} while(scores[i] < 0 || scores[i] > 100);
		
		if(scores[i] < scores[0]) {
			temp = scores[i];
			scores[i] = scores[0];
			scores[0] = temp;
		}
	}

	double average = (scores[1] + scores[2] + scores[3] + scores[4]) / 4;
	cout << "\n\nAverage of the four highest scores: " << double(average) << "\n\n";

	return 0;
}

Exactly how was I being an ass to someone?

It may not be necessary but it is what the OP has been asked to do!

Your welcome. I am glad you asked, it was fun to make this.
