Function

[kerem59]

Hello guys.I'm new at c++ programming.I have a question for you.The question is : Add a new function that find how many students have avscores>5 and calculate their average age.Which function should i need here?

  //Create a structure student with faculty number, name, age, avrscores. Create array with 5 students and calculate all avrscores,and
//find the student with age<20 and scores<5.
#include<iostream>
#include<string>
using namespace std;
struct student {
	string fnum;
	string name;
	int age;
	double avscores;
};

void create_data(student stud[]);
double avg(student stud[]);
void findstudent(student stud[]);



void main() {
	student stud[5];
	create_data(stud);
	cout << endl << "Total avrscores for 5 students is:" << avg(stud);
	findstudent(stud);

	system("pause");
}


void create_data(student stud[])
{
	for (int i = 0; i < 5; i++)
	{
		cin.ignore(1000, '\n');
		cout << endl << "Please enter faculty number";
		getline(cin, stud[i].fnum);
		cout << endl << "Please enter student name";
		getline(cin, stud[i].name);
		cout << endl << "Please enter student age";
		cin >> stud[i].age;
		cout << endl << "Please enter student scores";
		cin >> stud[i].avscores;
	}

}
double avg(student stud[])
{
	double total(0.0);
	for (int i = 0; i < 5; i++)
		total = total + stud[i].avscores;
	return total / 5;
}
void findstudent(student stud[])
{
	for (int i = 0; i < 5; i++)
		if ((stud[i].age <= 20) && (stud[i].avscores < 5))
		{
			cout << endl << stud[i].fnum; 
			cout << endl << stud[i].name;
			cout << endl << stud[i].age;
			cout << endl << stud[i].avscores;

		}

}

Hello kerem59,

If http://www.cplusplus.com/forum/beginner/274858/ did not answer your question I am not sure what you are looking for except it is the function(s) you hae not written yet.

In the "create_data" function line 33 should come after line 41 to work properly.

After that I will have to find what I worked on earlier to see what I did.

Guess this means that you have your answer?

That was fun to work on.
