struct / class - Need pointers

blackstar (30)
Need Pointers on this, went through my book again trying to solve this question and running into brick walls

define the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members. (Note that the data members of the class studentType must be private.)

Write a program to illustrate how to use the class studentType.

Struct studentType:

struct studentType
{
string firstName;
string lastName;
char courseGrade;
int testScore;
int programmingScore;
double GPA;
};


Test Contents

TEST(Grades, 1) {
testing::internal::CaptureStdout();
studentType student;
studentType newStudent("Brain", "Johnson", '*', 85, 95, 3.89);

student.print();
cout << "***************" << endl << endl;

newStudent.print();
cout << "***************" << endl << endl;
std::string output = testing::internal::GetCapturedStdout();
ASSERT_EQ(output, "Name: \nGrade: F\nTest score: 0\nProgramming score: 0\nGPA: 0\n***************\n\nName: Brain Johnson\nGrade: A\nTest score: 85\nProgramming score: 95\nGPA: 3.89\n***************\n\n");
}

It seems that this assignments wants you learn about getter and setter functions. Setter functions are used to manipulate the data while getter functions are used to fetch data. From what I learned, getter functions (in classes) are denoted with a const following the () as a way of "promising" to not modify anything within the class. After all, getters should only fetch data, not modify it.

Your class should looks something like this:
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
 
class studentType
{
  public:
    /* Getter functions */
    string getFirstName()        const;
    string getLastName()         const;
    char   getCourseGrade()      const;
    int    getTestScore()        const;
    int    getProgrammingScore() const;

    /* Setter functions */
    string setFirstName(const std::string&);
    string setLastName(const std::string&);
    char   setCourseGrade(const char&);
    int    setTestScore(const int&);
    int    setProgrammingScore(const int&);

  private:
    string firstName;
    string lastName;
    char courseGrade;
    int testScore;
    int programmingScore;
    double GPA;
};

Or similar.

If i did tht would i leave the struct student type as well since it wants to define the struct and then define the class with same components or would the struct be placed in one of the other files?
fiji885 (306)
You can't have the struct and the class share the name. Are you sure they want you to implement the both the struct and class with the same name? If so, you can't unless you use namespaces. It wouldn't matter if they're in different files, since the compiler will just link all the data in the end. Classes and structs will be declared (usually) in the header files if you want to use them in other cpp files, but that's usually for bigger programs.
blackstar (30)
i should probably take the grades from the last file and only put them in the middle file?

added void print(); above for the print
but im getting errors about being set to priavte
fiji885 (306)
What do you mean by "middle" file? The errors that you are getting are because you trying to access private data. This is why you have setter and getter functions, as they will access the data for you because they are part of the class.

Also, I made a mistake. The return type for the setters should be void (I was sloppy copying-pasting from the getters functions and made a small mistake).

These are your setter functions
1
2
3
4
5
6
 
    /* Setter functions */
    void setFirstName(const std::string&);
    void setLastName(const std::string&);
    void setCourseGrade(const char&);
    void setTestScore(const int&);
    void setProgrammingScore(const int&);


In your cpp file for the studentType, it should look like this:
1
2

/* In the cpp file, you will implement the functions of the class from

 */

/* For example, to the getter function for first name will be */
string studentType::getFirstName() const {
  return firstName;
}

/* And the setter function for the first name will be */
void studentType::setFirstName(const std::string& s) {

if i implement that should i scrap the other information i already had placed in my studentTypeImp.cpp?
fiji885 (306)
Yes. Scratch it and reimplement it. A lot of it should be scrapped, but some parts can be reused like this part:
1
2
3
4
5
6
7
8
9
10
 
if (score >= 90)
        newStudent.courseGrade = 'A';
    else if (score >= 80)
        newStudent.courseGrade = 'B';
    else if (score >= 70)
        newStudent.courseGrade = 'C';
    else if (score >= 60)
        newStudent.courseGrade = 'D';
    else
        newStudent.courseGrade = 'F';

You may have to modify it a bit.

In the end, I think you are trying to aim for something like this in your cpp file that contains the main function:
1

/* You can implement the print function here and use the getter functions to

void print(studentType& s) {
  cout << "Student" << endl
       << "-------" << endl
       << "First name: " << s.getFirstName() << endl
       << "Last name: " << s.getLastName() << endl

       << "Test score: " << s.getTestScore() << endl
       << "Programming score: " << s.getProgrammingScore() << endl;
}

int main() {
  studentType student;
  student.setFirstName("Richard");
  student.setLastName("Feynman");

  /* The setCourseGrade doesn't really have to be here. If you can find a way
   * to set the course grade from what the student scores are, that would also
   * work (which you get the idea as you have demonstrated above). */
  student.setCourseGrade('A');

  student.setTestScore(100);
  student.setProgrammingScore(100);
  print(student);

  /* If you have a user defined constructor, you can also do this */
  studentType student2("Bjarne", "Stroustrup", 'A', 95, 100);
  print(student2);

  return 0;
}


with its output being (similar to):

$ ./a.out 
Student
-------
First name: Richard
Last name: Feynman
Course grade: A
Test score: 100
Programming score: 100
Student

BTW i had a original working post posted at
http://www.cplusplus.com/forum/beginner/252211/
Now this one was working but not passing the argument, could their be any possible way to modify this one with the work above ?

First, let's take a look at your header file. In your studentType.h
file, you should have
1
2
 
#ifndef STUDENTTYPE_H
#define STUDENTTYPE_H


and at the end of the header file, you'll want to have an #endif .

On line 37, you are instantiating an object of the class studentType, which is
not what you're suppose to be doing. Can you explain to me what you're trying
to accomplish there so I can help you? Same thing going on with line 59. Lines
38 through 58 will not do anything useful. I can see what you're trying to do
there, but how you're implementing it is wrong. You should use a function
instead of doing what you're doing.



Now, let's take a look at your studentTypeImp.cpp file. On line 7, you have a
global variable. Remove it. I don't know why it's there. The studentTypeImp.cpp
file is suppose to be where you implement the functions from the class (look at
my example from above). Why do you have the fstream header included? Are you
suppose to read data in from a file? You're going at the cpp file the wrong
way. Implement the class functions from the header file into the header file.

You can reuse some parts, but you may have to adjust them to work. For example,
the user-defined constructor for the struct can be used again to work with the
class.

i oddly feel like im onto something here but confused as well. (mabye im going insane now) lol staring at this for the last 20 hrs
Took the old code and am currently modifying it

keep staring at the test output

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from Grades
[ RUN      ] Grades.1
/root/sandbox1014ee0d/nt-test-b5843ca6.cpp:14: Failure

Expected: output
Which is: "Name:    \nGrade:  \nTest score: 0\nProgramming score: 32\nGPA: 0\n***************\n\nName: Brain Johnson\nGrade: *\nTest score: 85\nProgramming score: 95\nGPA: 3.89\n***************\n\n"

[==========] 1 test from 1 test case ran. (0 ms total)
[  PASSED  ] 0 tests.
[  FAILED  ] 1 test, listed below:
[  FAILED  ] Grades.1

 1 FAILED TEST


if i keep staring at it im noticing some things especially here like mabye this shows what needs to be private/public/modified?

Value of: 
Name:  \nGrade: F\nTest score: 0\nProgramming score: 0\nGPA: 0\n***************\n\n
Name: Brain Johnson\nGrade: A\nTest score: 85\nProgramming score: 95\nGPA: 3.89\n***************\n\n

Expected: output
Which is: 
Name:    \nGrade:  \nTest score: 0\nProgramming score: 32\nGPA: 0\n***************\n\n
Name: Brain Johnson\nGrade: *\nTest score: 85\nProgramming score: 95\nGPA: 3.89\n***************\n\n"


the test contents are noted as this also

TEST(Grades, 1) {
  testing::internal::CaptureStdout();
  studentType student;
  studentType newStudent("Brain", "Johnson", '*', 85, 95, 3.89);

  student.print();
  cout << "***************" << endl << endl;

  newStudent.print();
  cout << "***************" << endl << endl;
  std::string output = testing::internal::GetCapturedStdout();
  ASSERT_EQ(output, "Name:  \nGrade: F\nTest score: 0\nProgramming score: 0\nGPA: 0\n***************\n\nName: Brain Johnson\nGrade: A\nTest score: 85\nProgramming score: 95\nGPA: 3.89\n***************\n\n");
}


now all that is based on this current code, so idk if the program is actually inputting or just trying to read and get the correct data out of it like a database

Don't work on modifying the old code. You're just going to confuse yourself
even more. You can use some of the old code, but you will have to modify
it. The goal here was that you turn the struct into a class and add
functions to manipulate the private data. Stick to what you had with the class.

define the struct studentType to implement the basic properties of a
student. Define the class studentType with the same components as the
struct studentType, and add member functions to manipulate the data
members. (Note that the data members of the class studentType must be
private.)


Look at the class definiton I had given you. All you literally have to do is
implement the functions in the cpp file. I am not sure what you're using to
compile or to even test, so that output doesn't tell me much.

I've said in previous posts that you have to implement the functions in the
cpp file. You've done none of it. I even provided you an example. From what
it seems, you don't don't really seem to know how basic classes work.

http://www.cplusplus.com/doc/tutorial/classes/

Read up on this before trying to do anything further.

sorry
fiji885 (225)

ill read over the classes again, my brain is all over the place and i dont really get all over it, specially getten confused bc i got 2 .cpp files
its how the grade compiler works on the cenage site.
ill read over your class link again and then read over my chapter again on classes and see if i can put something more together
and thanks for helping a dummy like me, i know its frustrating XD
