#include "ccc_win.h"
#include <fstream>


int ccc_win_main()
{

ifstream myfile ("hshape.txt"); //open my filestream

while (! myfile.eof())
{
//Asking for name of file
cout << "Enter the file name: ";
cin.getline(myfile,Point,'\n');
myfile >> value >> Point;
cout <<Point<<endl;

Make an MyFile.txt in the program folder, then run this

#include <cstdio>
#include <cstdlib>
#include <iostream>
#include <fstream>
using namespace std;

void safeFn()
{
    ifstream myFile("MyFile.txt");
    int nInputValue;

    for(int n = 1; n <= 10; n++)
    {
        myFile >> nInputValue;

        if (myFile.fail())
        {
            break;
        }

        cout << n << " - " << nInputValue << endl;
    }
}

int main(int nNumberofArgs,char* pszArgs[])
{
    safeFn();

    system("PAUSE");
    return 0;
}

And this will suit your needs:

#include <cstdio>
#include <cstdlib>
#include <iostream>
#include <sstream>
#include <fstream>
using namespace std;

int main(int nNumberofArgs,char* pszArgs[])
{
    char filename[256];
    cout << "Enter the name of file you want to open: ";
    cin.getline(filename,256);

    for(int s = 0;s != '\n';s++)
    {
        if(filename[s] == NULL)
        {
            filename[s] = '.';
            filename[s + 1] = 't';
            filename[s + 2] = 'x';
            filename[s + 3] = 't';
            filename[s + 4] = NULL;
            break;
        }
    }
    cout << "Opening and reading contents of '" << filename << "'" << endl;

    ifstream File(filename);

    for(int n = 1;;n++)
    {
        char object[256];
        File.getline(object,256);

        if(File.fail())
        {
            break;
        }

        cout << n << " - " << object << endl;
    }

    system("PAUSE");
    return 0;
}
