i want you to read each section, and i mean really read it. After you will have a full understanding and you will probably be kicking yourself. I myself did not even take a c++ class but this learncpp.com taught me everything (somewhat) that i know today

I promise If I can get thru tonight, I will print the entire thing and read it in and out....Ive only got one hour left tonight to finish my program. Did you get my email?

[nikc121]

Yes Im back.. Got an extension...I have my code up to par, I think. Did alot of reading on functions and arrays last night. This latest code is working ok, but only prints the average of the last number I enter. ANd I think I am missing average = sum/10 cout<<Average:"<<average;/ Im just not sure where it goes exactly. Again thanks to all the patients...You guys are way better than my instructor 3 days and no replies from her.

#include <iostream> 
using namespace std; 
 
const int NumScores = 10; 
 
int main () 
{   
    int score[NumScores];  

    for (int i=0; i<NumScores; i++) //loop that inputs arrays data
    { 
        cout <<"Enter score for 10 test:"<< (i+1) <<endl; 
        cin >> score[i]; 
	
    } 
    for (int i=0; i<NumScores; i++) 
    {  
        cout<<"Average for scores: "<<(i+1)<<" is "<<score[i]<<endl; 
		//system ("pause");
    } 
	int sum = 0;
	for(int i = 0; i<NumScores; i++)
	sum = sum + score[i];
	return sum/10;
}

int main() is the entry point of your program, when main hits its return value the program ends and the return value is sent to the Operating System. dont return the value out of main, just output the value

#include <iostream> 
using namespace std; 

const int NumScores = 10; 

int main () 
{ 
	int score[NumScores]; 

	for (int i=0; i<NumScores; i++) //loop that inputs arrays data
	{ 
		cout <<"Enter score for 10 test:"<< (i+1) <<endl; 
		cin >> score[i]; 

	} 
	int sum = 0;
	for(int i = 0; i<NumScores; i++)
		sum = sum + score[i];
	cout<<"Average : "<<sum/NumScores<<endl;

	//pause the window before closing
	cin.ignore();
	cin.get();
	return 0; //always return 0 from main
}

HI, Ive never used cin.ignor or cin.get. I changed the code but now have 5 errors. Error 5 error C2001: newline in constant c:\documents and settings\my documents\visual studio 2008\projects\arraycall3\arraycall3\arraycall3.cpp 24
Error 4 error C2143: syntax error : missing ';' before ':' c:\documents and settings\my documents\visual studio 2008\projects\arraycall3\arraycall3\arraycall3.cpp 24
Error 2 error C2065: 'Average' : undeclared identifier c:\documents and settings\my documents\visual studio 2008\projects\arraycall3\arraycall3\arraycall3.cpp 24
Error 1 error C2065: 'i' : undeclared identifier c:\documents and settings\my documents\visual studio 2008\projects\arraycall3\arraycall3\arraycall3.cpp 23

I cant win for losing.

you need to learn how to recognize compiler errors.

I havent even see the code but i will tell you what they are

error 1: your missing a semi colon somewhere
error 2: your using a variable that has not been declared yet
error 3: you have not declared the variable i

You STILL don't have a function!!! Hell-oooooo!?!?!

Dont worry, This is my first and last C++ class, after tonight youll never here from me. I just have to get this thing to run before midnight and then youll be done with me.

hes not saying to never return to DIC, were here to help you. Hes just pointing out that your assignment ask for your to use a function

Yea I know, Im not taking offense. By the way I found the errors, It did build but Im getting the error message when I debug that MSVCP90d.dll was not found. I ran into this before and ended up having to reinstall VS. So not sure what the output looks like, Im assuming its good..Since you did it....Im turning it in now..Wish me luck....

[jjl]

i thought you need to use a function? and dont just assume its good just because i did it, you need to understand how basic arrays work

[IngeniousHax]

If you come back...

#include <iostream>

//declare a function prototype
double avg(int a[])

int main()
{
//your codes to fill the array
total = avg(a[arrName]);
cout << "The avg of all the numbers is: " << total << endl;
return 0;
}

double avg(int a[arrName])
{
  //calculat the average
return (/*value of all numbers added than divided by total elements*/)
}

Your right. Instructor sent exam back says I need to use a funciton. I know the funtion is double avg (int a[]). If you look as some of my previous post I was using it, just in the wrong places. Now i just need to figure out after I put that above int main () what else I have to add.

[snoopy11]

I think your instructor is looking for something like this

#include <iostream>
using namespace std;

const int NumScores = 10;
int AverageScore (const int NumScores, int score[]);


int main ()
{
        int score[NumScores];
        int Average;
        for (int i=0; i<NumScores; i++) //loop that inputs arrays data
        {
                cout <<"Enter score for 10 test:"<< (i+1) <<endl;
                cin >> score[i];

        }
        Average = AverageScore(NumScores, score);
        cout<<"Average Score : "<<Average<<endl;

        //pause the window before closing
        cin.ignore();
        cin.get();
        return 0; //always return 0 from main
}


//***********************
//*function AverageScore*
//***********************
int AverageScore (const int NumScores, int score[])
{
int Average;
int sum = 0;
        for(int i = 0; i<NumScores; i++)
                sum = sum + score[i];
Average = sum/NumScores;

return Average;
}

but you need to read up on functions and how to call them.

[Kohana]

Snoopy you have taken my code and filled in the function for him. The objective is not to provide code to these people but help them understand. Never mind, there goes another computer scientist who will probably end up with a degree he doesn't understand.

[jjl]

Seriously its not a hard concept if you just read the material that i post for you. And i know you did not read the last material i posted becuase theres not even a funciton in your code.

start here and read each section
http://www.learncpp....k-at-functions/

Then read the part on arrays, if you dont understand any of this then i feel there is no chance that you will learn object oriented programming, which is key in c++
