Hey I need to make a program that reads information from a .txt file and outputs it on the screen and I have the basic understanding of reading/writing from .txt file. What I need ehlp with, is if I can get turing to read only part of the line because I have the name of the event and the date on the same line but I want them saved in separate variables. I have a picture here of the text file and also heres some code:

: * reads in the whole line. You can read in one word at a time, if you don't use it. Alternatively you could read in the entire line, and then figure out what is what in it. Perhaps with the help of index |

Before I begin to explain, do remember that there is more than one way to do things. I created a Database a little while back for a game (Maplestory) to hold all my data for items. In there I needed to hold a lot of variables in the same line. So when I decided how I was going to format my text file, I decided on a system like this:
After I decided on the format, I went through the file and took out all the data. (In the Turing Walkthrough, the tutorial File I/O explains how to do this. Aswell, the tutorial String Manipulation explains how to do what I'm about to talk about) Once I had all the data, I searched through each string. Now lets say I wanted to get the name. I'd go through the string and find the first [. Then I'd go through and find first ]. Finally, I'd assign the name to whatever was between [ and ]. Then I was able to do that for everything else. Likewise, I was able to easily get information in pieces. (I'll attach the Database if you'd like to see it. Warning: It's an old project, and the code is on the bad side. Though running the program will show you it in function, the code is rather messy and inefficient.) |

and thats actually sick. so you enter in items that you want to keep prices for so its kind of like a storage place for everything you enter in? |

Pretty much. I still play, too, just not much. I was going to add a remove button, and an edit button, but I have yet to. (You might notice the pictures in the file) I may go back to developing the program, but I'd be rewriting it. It's high innefficient, and quite stupid, in all honesty. Anyways, was your question answered? |
