    Read data from my .txt?

    I wanna make a program that can easily read data from my document!

    If I have a .txt with these values

    ABC 1 2 3
    DEF 4 5 6
    GHI 7 8 9
    I want to use it as a database...

    But how do I make a function that reads data from a specific line and pulls out the numbers behind and gives them all names like

    Name = "DEF";
    Value1 = 4;
    Value2 = 5;
    Value3 = 6;

    The thign I need is that that I can type in, I want the data from line 10 and then the program takes the data and puts in into my variables

    I want to use fstream btw... Iam just not very good at streams atm...

    struct CEntry
      std::string Name;
      int Value1;
      int Value2;
      int Value3;
    std::vector<CEntry> EntryList;
    std::ifstream File("MyData.txt");
      CEntry Entry;
      File >> Entry.Name >> Entry.Value1 >> Entry.Value2 >> Entry.Value3;
    } its simplest form. May need some tweaking/error testing though.

    So you are storing the data in a vector? Which I can then take the data from?

    Ahem - eof in a control loop FAQ ?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
