Help with a void function. For school

[cecil258]

Hey everyone... I'm in a beginning C++ class right now and below is the code I've written for my current assignment... What I need to do is put all of the input code (basically the huge chunk of stuff from main, into a void function. I'm not quite sure how to do this. I was just introduced to structs and arrays, and had trouble understanding functions when we were taught them a week or two ago so I'm a lagging a little bit. I don't expect you guys to finish my homework for me, but if someone could point me in the right direction and give me a sample or an idea of what to do, I would greatly appreciate it. Thanks, Adam.

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

struct Student
{
string name;
string address;
string city;
string state;
int zip;
char gender;
int id;
float gpa;
};




void printData(Stude nt& x)
{
cout << "Name=" << x.name << ", Address=" << x.address << ", City=" << x.city << ", State=" << x.state << ", ZIP Code=" << x.zip << ", Gender=" << x.gender << ", Student ID=" << x.id << ", GPA=" << x.gpa << endl;
}




int main()
{
Student a;
Student b;
Student c;

cout << "I need the following information for all 3 students " << endl;
cout << "Name: " ;
getline(cin, a.name);
cout << "Address: ";
getline(cin, a.address);
cout << "City: ";
getline(cin, a.city);
cout << "State: ";
getline(cin, a.state);
cout << "ZIP Code: ";
cin >> a.zip;
cin.ignore(1000 ,10);
