Reading File and printing it on the screen

[behzadkh]

Hey Guys;
I just saw a strange thing in my codes in reading file from a text file here is codes then I explain where is the strange thing...

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

int main(){
	char* name;
	int num;
	string s ;
	name = new char[20];
	ifstream fin;
	fin.open("students.dat",ios::in);
	if(!fin.good())
		cout<<"problem\n";
	else
		cout<<"fine";

	fin>>num;     \\first line in the file is number of lines
	cout<<num<<"number of record";

	while(!fin.eof()){
		cout<<"miracle";
		getline(fin,s);
		cout<<s;
       }
	return 0;
}

if i put cin.ignore(); before getline the out put wait for the enter and after entering appear....On the other hand, if i put \n in the end of cout<<"miracle"; half of the things come out....why?


thanks any one if explain what's happening when file is reading and the enter and cin.ingnore() what are doing over there?!....

cheers
