Classes and Object problem

[hpacleb]

I'm having trouble in our final project mostly dealing with classes and objects

#include<iostream>
#include<string.h>
#include<conio.h>
using namespace std;

class Student{
      public: 

        void SetQuiz(float q){
        quiz = q;
        }
        void SetMidterm(float m){
             midterm = m;
        }
        void SetFinals(float f){
             finals = f;
        }
        void SetProject(float p){
             project = p;
        }
        void SetName{string n){
             name = n;
        }
      protected:
          float quiz;
          float midterm;
          float finals;
          float project;
          string name;

             

};

class Students: public Student{
      public:
             char GetRank(){
                  //some equation to return respective grades and letter
                  return 'A';
                  }
      };

int main ()
{
    int x,c;
    string name;
    float lquiz,me,fe,pg;
    char k;
    cout << " Please enter the number of students in your class : " << endl;
    cin >> x;
    system("cls");
    
    for(c=0;c<x;c++)
    {
    Students s[c];
    }
    
    for (c=0;c<x;c++)
    {
        do{
        system("cls");
        cout << "Student #" << c+1;
        cout << "Enter name of student " << c+1;
        cin >> name;
        cout << "Enter long quiz result : "  ;
        cin >> lquiz;
        cout << "Enter midterm exam result : " ;
        cin >> me;
        cout << "Enter finals exam result : " ;
        cin >> fe;
        cout << "Enter project grade : " ;       
        cin >> pg;
        system("cls");
        cout << "Name of student : " << name << endl;
        cout << "Long Quiz Result : " << lquiz << endl;
        cout << "Midterm Exam Result : " << me << endl;
        cout << "Finals Exam Result : " << fe << endl;
        cout << "Project Grade : " << pg << endl;
        cout << "Confirm Submission? (Press Y to confirm)" << endl;
        k = getch();
        }while((k!='Y')||(k!='y'));
        
        s[c].SetQuiz(lquiz);
        s[c].SetMidterm(me);
        s[c].SetName(name);
        s[c].SetProject(pg);
        s[c].SetFinals(fe);
    
}
system("pause>0");
}

So many errors show up when I compile my code, can someone help me point out which ones should I change for it to work?

Okay, well first you should include <string> not string.h, string.h is for c style strings. Also on line 21 you put a bracket instead of parentheses. Then in line 55 you are trying to create variable length arrays on the stack? I presume that you meant to create a single variable length array, if so you need to create it on the heap or use a vector to do it for you. Thus, with a couple of quick fixes and the program will run.

#include<iostream>
#include<string>
#include<conio.h>
using namespace std;

class Student {
public:

	void SetQuiz(float q) {
		quiz = q;
	}
	void SetMidterm(float m) {
		midterm = m;
	}
	void SetFinals(float f) {
		finals = f;
	}
	void SetProject(float p) {
		project = p;
	}
	void SetName( string n){
	name = n;
	}
protected:
	float quiz;
	float midterm;
	float finals;
	float project;
	string name;



};

class Students : public Student {
public:
	char GetRank() {
		//some equation to return respective grades and letter
		return 'A';
	}
};

int main()
{
	int x;
	string name;
	float lquiz, me, fe, pg;
	char k;
	cout << " Please enter the number of students in your class : " << endl;
	cin >> x;
	system("cls");

	Students* students = new Students[x];

	for (int c = 0; c < x; c++)
	{
		do {
			system("cls");
			cout << "Student #" << c + 1;
			cout << "Enter name of student " << c + 1;
			cin >> name;
			cout << "Enter long quiz result : ";
			cin >> lquiz;
			cout << "Enter midterm exam result : ";
			cin >> me;
			cout << "Enter finals exam result : ";
			cin >> fe;
			cout << "Enter project grade : ";
			cin >> pg;
			system("cls");
			cout << "Name of student : " << name << endl;
			cout << "Long Quiz Result : " << lquiz << endl;
			cout << "Midterm Exam Result : " << me << endl;
			cout << "Finals Exam Result : " << fe << endl;
			cout << "Project Grade : " << pg << endl;
			cout << "Confirm Submission? (Press Y to confirm)" << endl;
			k = getch();
		} while ((k != 'Y') || (k != 'y'));

		students[c].SetQuiz(lquiz);
		students[c].SetMidterm(me);
		students[c].SetName(name);
		students[c].SetProject(pg);
		students[c].SetFinals(fe);

	}
	delete[] students;
	system("pause>0");
}

We haven't tackled about vectors yet but it wouldn't hurt to add it to my program so thanks for the input!
For line 55 , I have no idea how to define my class based on the user's input of number of students.
I want to make it work like this:
User inputs 10.

Student s1,s2,s3,s4,s5,s6,s7,s8,s9,s10;
