c++ Structures export data for specific name

structures

That is the structure that I created:

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


struct Students
{
	char first_name[10];
	char last_name[10];
	char country[20];


};
int main()
{
	Students array[10];
	int n, i;
	cin >> n;

	for (i = 0; i < n; i++)
	{
		cout << "Name:";
		cin >> array[i].first_name;
		cout << "Last Name:";
		cin >> array[i].last_name;
		cout << "Country:";
		cin >> array[i].country;

	}

	for (i = 0; i < n; i++)
	{
		cout << array[i].first_name << " ";
		cout << array[i].last_name << " ";
		cout << array[i].country << " ";


	}
	system("pause");


}

And I have to write code that once I enter John (for example) displays all information about him: last name, country. And when I enter country to export: first name, last name. Maybe I don't explain it properly. Because my english is bad. Maybe that's the reason that i can't find specific information or similar examples.

Ouput example:

n=2
Name:John
Last Name: Doe
Country: England

Name:Pete
Last Name: Donaldson
Country: USA

And that's the part that i can't do:

/Info about student/
Enter Name for check:
John

and here the output must be:

Name:John
Last Name: Doe
Country: England

another check:
if I enter Pete:

Name:Pete
Last Name: Donaldson
Country: USA

I should be able to make unlimited checks.

I tryed to make it like this:

for (i = 0; i < n; i++)
char name_for_check[10];
cin >> name_for_check;
for (i = 0; i < n; i++)
{
	if (strcmp(array[i].first_name, name_for_check) == 0)
	{
		cout << array[i].first_name << " ";
		cout << array[i].last_name << " ";
		cout << array[i].country << " ";
	}
}
}

But how to do so that I can make an unlimited number of requests for name_for_check.
I mean that i can check name more than one time.
