Input file help

[UndeadNexus]

I am having trouble making the program open a file. What this program does is that it prompts the user for a file name so that it can open that file and count the number of chars, words and lines it contains (like when using the wc command). I'm coding it in a way where it keeps asking the user for another file name until the user hits ^C. Any suggestions?

#include <iostream>
#include <string>
#include <sstream>
#include <fstream>

using namespace std;

main()
{

    string word, line, fish;
    int chars = 0, words = 0, lines = 0;
    istringstream line_string;
    
    cout << "Enter file name: " << line;
    getline(cin, line);
    while (!cin.eof())
    {

        ifstream myfile (line);

        lines++;

        chars += line.length() + 1; 

        line_string.str(line); 

      
        while (line_string >> word) 
            words++;

        line_string.clear(); 
        
        getline(cin, line);

        cout << lines << ' ' << words << ' ' << chars << endl;

    }

   
}

I changed some code around and it sort of works. I just need help on making it open files

#include <iostream>
#include <string>
#include <sstream>
#include <fstream>

using namespace std;

main()
{

    string word, line, fish;
    int chars = 0, words = 0, lines = 0;
    istringstream line_string;
    
    while (!cin.eof())
    {
        cout << "Enter file name: " << line;

        getline(cin, line);

        lines++;

        chars += line.length() + 1; 

        line_string.str(line); 
      
        while (line_string >> word) 
            words++;

        line_string.clear(); 

        cout << lines << ' ' << words << ' ' << chars << endl; 
        
        line.erase();

        lines = 0;
       
        words = 0;

        chars = 0;
      
    }

    
}

You should always put int in front of the main function even if the compiler allows you to do it with out int.
maybe try something like this

#include <iostream> //std::cout , std::flush , std::endl
#include <fstream> //std::ifstream

int main()
{
    std::string input = "" , info = "";

    std::cout << "Please enter the filename.\n> " << std::flush;
    std::getline( std::cin , input ); //best to use getline for strings not cin
    
    std::ifstream in( input.c_str() )
    while( in.good() )
    {
        std::getline( in , info );
    }
    std::cout << info << std::endl;
}
