    You can use remove(char* filename) to do this task.

    remove() is not a ofstream member function, if you include <cstdio> it will be a global function so you can call it like this -

    int deleteContact()
    {
    remove("blah.txt");

    return menu();
    }


    assuming that blah.txt is in your current directory. Otherwise you'll have to include the full path for the file.

    The default behavior of getline is to terminate when a newline is entered. I'm not sure what you mean by ternial_char, but is quite easy with i/o to leave characters in the buffer that affect how getline works. Post the code.

    Ooops my bad. I neglected to say that remove() is a regular c function. I'll be more specific next time.
