reading in chars from file

[AJOHNZ]

ok i have a few questions about this code. it is supposed to display the first name alphabetically and the last name alphabetically from the list.

1. i don't think the strcpy function has been covered yet in the book so i was wondering if there was a different way to assign the current char to the first and last variables.

2. when i used the strcpy function i got a warning saying i should use strcpy_s instead. i have no idea what the difference is could someone explain.

3. when i read in the file it prints to the screen just right but the "last" student is displayed as what i initilized it as which is "aaaaa". how come the name after that alphabetically is not being stored in the "last" variable?

here is my code so far:

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

int main()
{
	ifstream infile;
	infile.open("LineUp.dat");

	if (!infile)
	{
		cout << "Corrupt File " << endl;
	}

	int numStudents = 0;
	char first[21] = "zzzzzz";
	char last[21] = "aaaaaaa";
	char name[21];

	while (infile >> name)
	{

		if (strcmp(name,first) < 0)
		{
			strcpy_s(first, name);
		}
		if (strcmp(name,last) > 0)
		{
			strcpy_s(last, name);
		}
		cout << name << endl;
		numStudents++;
	}

	cout << "The first student is " << first << endl;
	cout << "The last student is " << last << endl;
	cout << "There are " << numStudents << " students. " << endl;

	return 0;
}

> #include <cstring>
Since this is C++, why are you using C strings at all?
They're horrible and bug prone compared to the C++ version.

#include <string>
	string first = "zzzzzz";
	string name;

	while (infile >> name)
	{

		if ( name < first )
		{
			first = name;
		}
