I have 3 methods one that inputs the details of the students, one that inputs the marks and one to view student details and their marks. My question is how I can use a hash table to get the Id of a student and then use it to input the marks and then how to retrieve both the student details and their marks altogether. Please help me if you can.

  • easy hex/float conversion

    - by yeus
    I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link: http://docs.python.org/library/stdtypes.html#additional-methods-on-float Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes... thx for the answers!

    - by Zubair
    I would like to evaluate some clojure code entered by users interactively, and I would like to "use" certain namespaces and "import" certain Java classes as well. I end up running the code using: (defn execute-command [string-command] let [ code-with-context (add-code-context string-command) result (eval(read-string code-with-context)) ] result ) My question is how can I program "add-code-context" to add the required context to the code in "string-command"?

    Hi Using RubyMine 2.0.2 for the first time today, on Mac OSX Leopard. If I create files in the filesystem (with, say, script/generate) those new files do not appear in rubymine. I have had limited success with restarting the program, in that the files in the db/ folder are added and removed, but unfortunately new folders in the views directory are not shown. Pardon my french, but wtf? Thanks

  • Typed metaprogramming languages

    - by Jacques Carette
    I want to do some metaprogramming in a statically typed language, where both my programs and my meta-programs will be typed. I mean this in a strong sense: if my program generator compiles, I want the type system to be strong enough that only type-correct programs can be generated. As far as I know, only metaocaml can do this. (No, neither Template Haskell nor C++ templates fit the bill -- see this paper).

  • Changing the icon of a .JAR file

    - by Demonick
    How can I change the icon of a .JAR file I want to distribute? I have changed the icon that shows when the program is run, but I want to change the icon in the environment (e.g. Windows XP), that is for the file itself. I googled, but the best I could find is converting the .JAR to a .EXE, which is not the best choice.
