Don't do stuff like this. Here's a rule of thumb: Forget about char arrays, use std::strings instead. i.e.

// Console.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
 
int main(int argc, char* argv[])
{
	ifstream ifs("C:\\a.txt");
	if (ifs)
	{
		unsigned int line = 1;
		string s;
		while (getline(ifs, s))
		{
			cout << "Line " << line++ << ": " << s << endl;
		}
	}
 
	return 0;
}

Unless you're optimising code or have some other compelling reason don't get user input in char arrays.

init_statement;
while (condition) {
    instructions;
    increment_statement;
};
