Reading in characters

[Wynd]

I want to write a program that opens a file with ifstream and reads each character in the file and prints it out. This is what I have so far:

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

int main()
{
    char a;
    ifstream fin;

    fin.open("test.txt");
    fin >> num;
    cout << num; // Works OK

    while (!fin.eof()) // ?
    {
        // What goes in here?
    }
    fin.close();

    return 0;
}
