Call to a function

[Zenith1900]

Helle, i need a function printsresults, not a member function, to print out final couts. I don't understand how to call that function from the main and what parameters it should receive.

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;

class Quizdata
{
	private:
		 string  name;
		 double total;
		 int   number;
		 
	public:
		Quizdata(string n){
			setName(n);
			total=number=0;
		}
		
		void setName(string studentName){
			name = studentName;
		}
		string get_name(){
			return name;
		}
		int add_quiz(int, int);
			
		
		
		double get_total_score(){
			return total;
		}
		double get_average_score(){
		    return total/number;
		}
	
};

int Quizdata::add_quiz(int n, int grade)
{
	int quizNum = n;
	int score = grade; 


	while ( n!=0){
        cin>> grade;
    if (grade>=10 && grade<=100){
        total +=grade;
        number++;
    	n--;
		}	
	else 
		{
		cout << "Invalid input, score range is from 10 to 100";
		}
	}
}
    	


int main()
{
	string name;
	int quizNum, score, total;
    
    cout << "This program accepts students' name,\n"
         << "number of quizes and their scores.\n"
         << "Quiz scores must be in the range of 10 to 100\n";
	cout << "\nWhat is the students name? ";
    getline(cin, name);
	Quizdata student1(name);
    cout << "How many quizes grades would you like to enter? ";
    cin >> quizNum;                                                //why cant move to add_auiz???
    cout << "Enter " << quizNum << " quize grades: "; 
    student1.add_quiz(quizNum, score);
		                             //Move to printresults???
    cout << fixed << showpoint << setprecision(2) << endl;;
    cout << "\nStudent's name is:\t" << student1.get_name() <<endl;
    cout << "Student's total is:\t" << student1.get_total_score()<< endl;
    cout << "Student's average is:\t" << student1.get_average_score()<< endl;

	return 0;
     
     
}

try the following?

void printresults(Quizdata student_to_print)
{
  // code to print here
}

[Zenith1900]

doesnt seem to work, It must be the call from the main that wrong. What would the call look like?

[squished18]

The call should be

printresults(student1);

[novellof]

so you need a function that takes in the object as a parameter?

void print(Quizdata qd)
{
  // then print anything associated with the class like: 
   cout << qd.name << endl; 
  
}

When you call the function it will look like this

Quizdata student; //declare your object

print(student); // pass in the instance of the object name
