    #1 cin.getline() works with c character arrays
    Code:
    char cMOvie[255];
    cin.getline(cMovie,sizeof(cMovie));
    if you use std::string object
    Code:
    std::string cMovie;
    getline(cin,cMovie);
    #2: I never heard of getwidth(), but that doesn't mean it doesn't exist

    To use it with strings

    Code:
    getline(cin,string_name);
    cin can also be replaced with a file stream, ect.

    Code:
    getline(cin, sMovie);
    Problem with that, if there is a space (example "The Matrix") I need to hit enter twice.

    So how do you format your output in a console window? (with coulombs)

    Let me guess, VC6.
    That is actually a bug in VC6. They fixed it in .net but did not fix it in any of the service packs for VC6.
    Get a different compiler

    Specifically look a setw

    *edit*
    Btw though, you can fix the getline function your self:

    That is a pretty well known bug in VC6, and I fixed it on my compiler, but as I remember it, it was very hard to figure out which file contained the line of code you are supposed to change: msdn didn't have clear instructions on that.

    This is probably the solution to the problem.

    That's the same link Enahs gave. Here's another one: http://www.dinkumware.com/vc_fixes.html

    The file you need to modify is <string>.
