    C++ style tables

    Hi everybody!

    The project I'm working on contains a lot of tables, which are now defined as pointer-type arrays :
    Code:
    typedef struct {
      string name;
      double value;
      int multiplicity;
    } myParameters;
    
    static const double just_some_parameters[] =
    {
      {"one", 1.0, 1},
      {"two", 2.0, 2},
      {"three", 3.0, 1},
      {"four", 4.0, 2},
      {"five", 5.0, 3},
    };
    I would like to convert this to a more STL like array, but then I'll probably need a (static) function to initialize my tables ? I mean:
    Code:
    typedef struct {
      string name;
      double value;
      int multiplicity;
    } myParameters;
    
    static const std::vector<myParameters> = {} // will not work, of course
    Any ideas of how to get rid of pointer-type arrays when using tables ?

    Thanks for your answer!

    Two choices:
    You write code to convert your static array into the vector.
    Write code to push_back(myParameters("one", 1.0, 1)) etc.

    Third choice: leave this stuff as it is. There's absolutely nothing wrong with it.

    I fully agree with that.
