Movie Ticket Program. struct, ifstream

[Gujuboy]

I have assignment to do, but i dont know how to start it off. I read from a text file( also print movies r playing first) , read each line and assign to each string and next line is the price so and customer should be able to choose a more then one movie, and at the end print the add up the price with tax(5%). can some one help me please. Thankx alot in advance.

so here is the output should be like

This is my movie.txt file

Transformers                       
$8.50
Rush Hour 3                        
$8.50
The Game Plan                   
$9.50
 
 

This is Output I want.

Movies that are Playing now:
 
Transformers                       $8.50
Rush Hour 3                        $8.50
The Game Plan                   $9.50
 
Your Movie Ticket:
 
Rush Hour 3                        $8.50
The Game Plan                   $9.50
 
Total:                                 $18.00
Tax:                                   $0.90

Like how to start off da program. i could get struct fuction in put file, i could get to da point where it will print whole file in screen but i dont kno whow to get each line and assingt it to each string. like let say

struct movieNametype
     {
          char movieName [ ]
          double price;
     }
 
movieItemtype movies[30];

so let say

ifstream InFile;
InFile.open ("movies.txt");

so here is the question how do i get to read each line from "movies.txt" file and assign it like this

movies[0].movieName="Rush Hour 3";
movies[0].price=8.50;

and this repeats until to end of it.

Yea i read that before, but i dont get it how to read from file and assign to string line by line.

You're going to need an array of strings, and if you can't read that and figure out how to read from a file, you're going to have to tell us why you don't understand that - we can't read your mind and figure out what you're stuck on.

[Gujuboy]

okay, let say


cout<<"movie name: ";
cin>>movie_name;

okay so how do i get each line from a file (movies.txt) and
cin>>movies[0].movieName;

so if first line in file says Rush hour 3
it should be stored in movies[0].movieName
.. i guess i explained ma self this time?

cout<<"movie name: ";
cin>>movie_name;

cin>>movies[0].movieName

Yep. That's pretty much exactly it, only in a loop so that you pull the line in to a different spot in the array each time, and you test that the file hasn't reached the end. You'll probably want to increment the array index, and you're not using cin. I believe there's another that might be better for C++, let me look it up.

But aside of that (and having looked at the getline page) do you understand it? If not, can you post the line you're having trouble with?

#include <fstream>

fstream InFile;
char str[2000];
InFile.open ("C:\Documents and Settings\%username%\Desktop\movie_c\movie.txt",ios ::in);
while (!InFile.eof())
{
InFile.getline(str,2000);
cout<<str;
}

it compiles but, i dont get any output in screen?

Have you added:

system("PAUSE"); 

at the end??

yea,, i have getch(). wat i ment i dont get anything on screen for output is dat... i dont get any output. screen is there but No OUTPUT whatsoever.

You need to post the code - we're sitting here guessing and giving you functions, but we've seen no implementation. If you're not getting output, are you getting errors? Are you printing stuff out, or are you printing stuff to a file? I know you're reading in from a file (wasn't that in your original problem?), so are you printing it out after that, or are you just performing some action (adding movie to db, removing from collection, throwing it against the wall, etc...) and then not printing to standard output (cout) the success or failure of that?

Code that i have in my previous post. datz one i am useing to read from jst file and print out thats it. same code. it compiles everything no error, but in OUTPUT SCREEN, nutthing prints on it. so i dont know what is the problem there because, there is no error or anything it just doesnt print anything on it.

Can you post your whole program?

[Gujuboy]

Can you post your whole program?

{
 
    char str[2000];
    fstream file_op("C:\Documents and Settings\Administrator\Desktop\menu_c\menu.txt",ios::in);
        while(!file_op.eof())
        {
              file_op.getline(str,2000);
              cout <<str;
        }         file_op.close();
        cout <<endl;
 
 
}

[sicarie]

First of all, you need to put 'using namespace std;' after your library declarations.

    fstream file_op("C:\Documents and Settings\Administrator\Desktop\menu_c\menu.txt",ios::in);
 

Then, I believe this is your problem, you need to be backwhacking the filepath - the compiler interprets a single backslash as an escape character so you can use things like \n, \t, etc... which are newline and tab characters. So your compiler is trying to figure out what \D, \A, \m mean, etc... So you need C:\\Documents and Settings\\yourpath\\your file.

PS - as we have a policy against posting full code, I've snipped it down, but that's just due to the forum rules.
