    the end of file is a flag that literally marks the end of a file. YOu could use it while reading a file

    so

    while(!=EOF)
    read file

    you dont have to define it as when the data in a file ends there is an eof flag - i think its marked by a -1 value but im not 100% sure on that

    well how would EOF work in this code?



    #include <iostream.h>
    int main()
    {
    char ch;
    int count = 0;
    cin.get(ch);
    while (cin.fail() == false)
    {
    cout<<ch;
    count++;
    cin.get(ch);
    }
    cout<<"\n"<<count<<"characters read\n";
    return 0;

    }

    how does taht get the output of

    u type in anything u want
    it repeats itself once
    keeps this apttern up till u hit ctrl+z

    how does that work

    there are no references to eof in that code, it uses cin.fail() - im not quite sure what this does - its something do with the data stream being checked for 'bad' values - i dont know if EOF is included in that.
