Question

I am suppose to create a program to compute a students weighted course grade but I am not getting the results I want and the the program to display how I want it to. Below is the intstructions for the project along with how it is suppose to output when ran but when I debug my code and run it it does not compute the overall average how I want it. when I use the numbers given in the example to test the program it outputs an overall grade of 94.4 instead of the average 80.93. I also for some reason can't get the percent sign to show. I am missing a step but not sure where..I knwo that 101/150 is

Answer 1

Write a program to compute a student's weighted course score. There are three tests in the class. The user should enter the maximum points for each test (they do not have to be the same) (integer), the student's score on each test (integer), and the weight of each test (as a percent of 1.0 (0.4 = 40%)) (floating-point value). Your code should output the student's weighted course grade.

Example 1:

Weight of first test: 30
Maximum on first test: 100
Score on first test: 93

Weight of second test: 30
Maximum on second test: 100
Score on second test: 87

Weight of third test: 40
Maximum on third test: 150
Score on third test: 101

Your overall grade is 80.93%

Answer 2

my code
#include <iostream>
#include <string>

using namespace std;

int main()
{




int score1 = 0;
int score2 = 0;
int score3 = 0;
int test1 = 0;
int test2 = 0;
int test3 = 0;
double weight1 = 0;
double weight2 = 0;
double weight3 = 0;
double weight = 0;



cout << "Weight of first test:";
cin >> weight1;

cout << "Maximum on first test:";
cin >> test1;

cout << "score on first test:";
cin >> score1;





cout << "Weight of second test:";
cin >> weight2;

cout << "Maximum on second test:";
cout >> test2;

cout << "Score on first test:";
cin >> score2;






cout << "Weight of third test:";
cin >> weight3;

cout << "Maximum on third test:";
cin >> test3;

cout << "score3 on first test:";
cin >> score3;



weight = score1* weight1 + score2 * weight2 + score3 * weight3;

cout << " Your overall grade is " << weight << "\n";

system ("pause");
return 0;



}

Answer 3

not sure what I am not seeing or missing..

Answer 4

cout>>test2; it has to be cin>>test2;

Answer 5

oh wow .. how did I not catch that

Answer 6

ok when changed it still doe s not compute how I want it too.. am I missing an equation

Answer 7

ya. that's vat I am working on right nw:)

Answer 8

You should probably divide the score of the test by the maximum score somewhere.

Answer 9

so I would make intergeer for the equation lilke int score1= score1/test1?

Answer 10

(( score1* weight1)/test1)

Answer 11

so it would be int double then

Answer 12

For as far as I know `int double` doesn't exists. It'll be just `double`.

Answer 13

u have to divide the product of score and weight by the corresponding maximum score nd finding the sum of them gives u the desired output

Answer 14

Does that help? @RemyJDH

Answer 15

yes that makes sense. I was in ball park but had it jerry rigged

Answer 16

thank you for your assistance

Answer 17

also quick question this has been baffling me. how do I create spaces between lines.. I know it something simple but I can t seem to remeber how to do it.

Answer 18

welcome:) for the percentage sign u can include it in the cout statement after weight

Answer 19

Add "\n" to your string or use cout << endl;

Answer 20

when I use the endl; or "\n" on my cout statement it does not output in format below

Weight of first test: 30
Maximum on first test: 100
Score on first test: 93

Weight of second test: 30
Maximum on second test: 100
Score on second test: 87

Weight of third test: 40
Maximum on third test: 150
Score on third test: 101

Your overall grade is 80.93%

Answer 21

Sorry, I probably misunderstood you. What output do you have right now?

Answer 22

it spaces my input. so it ask the question and imy input will be under the sentence I can seem to create space between the the groups like when writing a new paragragh

Answer 23

If I understand correctly, you have output something like this:

Weight of the first test:
100

while your code is something like

cout << "Weight of first test:\n";
cin >> weight1;

If that's the case, you just need to replace the '\n' by a single space and it should be fine.

Answer 24

let me see f that works

Answer 25

I still get no spcae between the groups it out puts like this below

Weight of first test: 30
Maximum on first test: 100
Score on first test: 93
Weight of second test: 30
Maximum on second test: 100
Score on second test: 87
Weight of third test: 40
Maximum on third test: 150
Score on third test: 101

Answer 26

instead of Weight of first test: 30
Maximum on first test: 100
Score on first test: 93

Weight of second test: 30
Maximum on second test: 100
Score on second test: 87

Weight of third test: 40
Maximum on third test: 150
Score on third test: 101

Answer 27

After each cin statement which enables u to input test score insert cout<<endl;. hope this works:)

Answer 28

cout << "Weight of first test:";
cin >> weight1;

cout << "Maximum on first test:";
cin >> test1;

cout << "score on first test:";
cin >> score1;
cout<<endl;
cout << "Weight of second test:";
cin >> weight2;

cout << "Maximum on second test:";
cout >> test2;

cout << "Score on first test:";
cin >> score2;
cout<<endl;

Answer 29

let m see if that works

Answer 30

hmm k:)

Answer 31

IT WORKED OMG .. sweeet

Answer 32

not i can apply that to my outher project im working on too and it will be complete yay

Answer 33

now*
