Please help c++ program

I need help with the char function where i have to take the % and change it to the corresponding grade . and also the output function which has to look like this , we use setw()

Code:

---------------------------- | EXAM | SCORE | GRADE | ---------------------------- | HIGH | 100 | A | ---------------------------- | AVG | 83 | B | ---------------------------- | LOW | 61 | D | ---------------------------- | 1 | 100 | A | ---------------------------- | 2 | 73 | C | ---------------------------- | 3 | 94 | A | ---------------------------- | 4 | 61 | D | ---------------------------- | 5 | 87 | B | ---------------------------- # include <iostream.h> # include <iomanip.h> # include <math.h> // This program asks the user to enter a series of test scores // // Then it will determine the highest , lowest , and average scores// // The corresponding letter grade will be assigned to the scores// // And finally a table of output will be displayed// // ***** VARIABLE DECLARATIONS ******// int promptscore (void); void displayoutput (int[], int ); char examgrade (int); int avggrade ( int[], int ); int highestgrade ( int [], int ); int lowestgrade (int [] , int ); void clearscreen (void); const int maxels = 8; //maximum # of array elements int examscore [maxels]; //****** MAIN PROGRAM BODY *************// main () { int score , i = 0; clearscreen(); score = promptscore(); while (score = 0 && i < maxels ) { examscore[i++] = score; if ( i < maxels ) score = promptscore(); } displayoutput(examscore , i); } //****** THIS IS THE PROMPT FOR SCORE FUNCTION******// int promptscore(void) { int examscore; cout << " enter score , enter a negative number to quit : "; cin >> examscore; return examscore; // ******* THIS IS THE FUNCTION FOR HIGHEST GRADE *******// int highestgrade ( int exam [], int nbrofexams) { int i , highestgrade; highestgrade= exam[0]; for ( i = 0; i < nbrofexams; i++) { if (exam[i] > highestgrade) highestgrade = exam[i]; } } // ********** THIS IS THE LOWEST SCORE FUNCTION ********// int lowestgrade ( int exam [], int nbrofexams) { int i , lowestgrade; lowestgrade= exam[0]; for ( i = 0; i < nbrofexams; i ++ ) { if( exam [i] < lowestgrade) lowestgrade = exam[i]; } } //*** THIS IS THE INCOMPLETE !!!!!!! AVERAGE GRADE FUNCTION *****// float averagegrade ( int grade [] , int n ) { int sum = 0; for ( int i = 0 ; i < n; i ++ ) sum += grade [i]; return (sum) / n; } //!!!!!!!!!!!!! CHAR EXAM GRADE FUNCTION !!!!!!!!!!!!!!// // !!!!!!!!!!!!!! CLEAR SCREEN FUNCTION !!!!!!!!!!!!!!!!!!// void clearscreen(void) { cout << "\033[2j\033[h"; }

// !!!!!!!!!!!!! DISPLAY OUTPUT FUNCTION !!!!!!!!!!!!!!!!!!!!!!//

What exactly do you need help with?

No one here is going to your homework for you.

gg

What's so diificult about
if ( score >= 90 ) grade = 'A';
and so on through the score ranges

> while (score = 0 && i < maxels )
You don't want an assignment there. From code elsewhere, I guess you meant
while (score > 0 && i < maxels )

> int i , highestgrade;
Having a local var with the same name as the function is very poor style. Name shadowing (where an inner scope name hides an outer scope name) can lead to all sorts of fun.
Besides, there is no
return result;
in these functions

> void displayoutput (int[], int );
Naming parameters is a good idea - especially when you start writing code which spans many files.

You also seem to have creeping indentation. The file is becoming progressively more indented as you go.

you have to understand this is my first programming class , i was just asking for some help i have no idea how to go about forming the table for the output I know i can make a const char line = "-------------" to make the first line and divider lines too i guess but putting it all together is where im a little flustered

i dont think the functions were supposed to return results , simply do the work so that it can be outputted into the final table

So write some code which has a few cout statements to ouput the raw information.

cout << "HIGH" << highestgrade << endl;

One you've outputted all the information, then start refining the formatting by using setw() and some cout statements for the dashes.

was just looking for some help finishing my last 2 functions , im not a kid im trying to learn this stuff at 28 years old and never having a c or c++ class before

so cut me some slack im not asking anyone to do my homework for me i got most of it done myself

im just having trouble putting everything together , i have most of it but just not sure how to complete it ,, i dont know its frustrating im sure youre looking at this like youre kidding right but its supposed to be an intro class and believe it or not theres 6 of us left in the class from over 20

it is not that tough if you think about it you put your graes in a heap and the heap is already sorted then you take all the grades in the heap and add them together then divide by how many tests there are and if you want you can use modulus to find the exact average you dont need hardly any of that stuff that you are doing now but you might have to read about heaps if you dont know

this is the way we were supposed to do it for class , he named the functions and said do the program

you can still use heaps just read up on them you will understand

ok ill look it up

Don't worry about it :) Everyone has to start somewhere, and were here to help.

My FULL advice on this one, is pseudo code! Write out everything you need to do in your program, and examine how you would do it with what you know and whats required. Then start writing your functions. If you have good pseudo code everything will make sense to you.

>was just looking for some help finishing my last 2 functions

But, beyond that..what functions do you need help with? And what do you need them to do?

well i guess if i sit down ill be able to figure out my output table , and for my char function i need it to assign a grade to the test %

so i guess all i do is take the inputted grade and do the

if ( grade > 90 )
grade = 'A'

i know thats rough but the idea

im worried about setting the table

By the way salem I went to your website , and im not here trying to get people to do my homework i had 80-85% of it done myself . You have to remember this is my first class , and also that you were not born a computer genius . Im just trying to get through school while working full time to better my career .

Not looking for a free ride this was my first ever post for help

Its just a simple matter of calling the relevant functions in the right order, with lots of cout statements.

First 3 lines are HIGH, AVG and LOW, so my guess is you call

highestgrade ( examscore , i );
avggrade ( examscore , i );
lowestgrade (examscore , i);

say

Code:

cout << "| HIGH |" << setw(6) << highest << " | " << gradetocode(highest) << " |" << endl;

And the rest is just a for loop iterating through the array of individual scores.

thank you for your help

FYI, you claim you have 80-85% of the code done. What you posted was less than 1% done. You should post at least the portion of the code you are having trouble with so we can see what you are doing and be able to help you. That would have helped us not waste time with 7 or 8 irrelevant posts.

So for next time, post enough info to give us a complete picture of the difficulty.

Well Walt if you would have read through all the irrelevant posts you would have seen that this is my first class , and 80 -85 % of the overall code was complete - if you find my post and the replies irrelevant then dont bother replying , like I said before you all werent born computer programmers , you started somewhere . Now I am starting somewhere and since im having trouble with the info I was asking about , I may have not been able to communicate properlyy what I needed help with exactly , but dont worry I wont post anything else since this seems to be a website where everyone is an absolute genius and forget where they started from .

I apologize. With the advent of the new board, I completely missed the rest of the code. I did not notice the scroll bar since this board never had them before. All I noticed was up to an include.

It wasn't your fault, it was mine.

its ok its just frustrating for me ive been out of high school since 1993 and this is my first programming class and i know to most of you it looks easy but to me and my classmates its really starting to get hard for us . I really dont want a free ride because i wont learn anything and this is the first class if i dont get everything i need from it I will fail in all my future classes .

No hard feelings , I appreciate the message .

Computer programming is a great interest of mine i love working it through and seeing the end result .

And I promise I will never ask what int means

You know what walt I just looked at my original post and I dont see a way to scroll through the rest of my program , do you have to reply to it to see the full code ?
