Problem with C++ Exercise
 
Hey guys.. Im stucked at my final exam with this exercise

To create a class UnordArray which can store
a number of data (integers), the new
embedded data are placed at the end of the structure.
Create a class described by creating appropriate
header and implementation files, which contain
following data:

• buffer, which is a sequence of integers in which
stored data.
• numElem, which represents an integer which stores the number
the currently inserted in the data structure.
To define a constructor, which landed the initial
value of data member numElem. To define
following functions of the class members:

• int size (), which returns the number of data
structure.
• void insert (int val), which inserts the data value
val at the end of the structure.
• boolean delete (int val), searching the structure and if
it does not contain data with a value val, returns false; in
Otherwise removes data with value val, January
terminator structure, and returns true.

• int find (int val), searching through the structure if it
contains data with a value val, returns -1, otherwise January
Returns the value of the index which is the value val
structure.

• void print (), prints the data structure in
order from beginning to end.
To create a file koristi.cpp, which will be demonstrated
use of the newly created class and all UnordArray
Its features members. When creating the class
It is forbidden to use ready-library classes and
functions (other than iostream).

I Tryed 1000 times to make it work but it's always says SOMETHING MISSING!!!!:freak::freak:
Can u give me a hand here pls? ... Maybe some 1 can wrote some part of it.. or anything ? Pls guys , let's do it :S
Thank you
Kabom

You say that the you have tried 1000 times but can you tell me what you have coded so far ?

SOMETHING MISSING doesn't look like any C error message I've ever seen.

Post the latest version of your code (use code tags) and the error messages from the compiler and let's see what the problem is.

What version of what compiler are you using, and what operating system?

Code:

      }
           
      void insert(int val)
      {
          if(numElem >= 100)
                      cout << "Bufferot e veke poln! Nemozete da vnesuvate veke vrednosti" << endl;
          else

Im done.. if u want to translate it at english u can try it ;) it's on my Language - MACEDONIAN
see ya

So does the program compile without any errors? If not what are the error messages??

Re: Problem with C++ Exercise
 
What errors did you get? I compiled it in Visual Studio 2008 and got no errors, just one warning about an unused variable temp.

Tried running it but I don't speak Macedonian so haven't got a clue what it says or is supposed to do. If the problem is not that you got compile errors but that the runtime behaviour differed from what you expected, what input did you give, and what output did you expect? Remember I can't see your screen or read your mind, so I need some other way of understanding what the problem is.

By the way you don't need to ask if you need to translate code into English. The answer is almost always going to be yes, unless by sheer chance you just happen to get someone who speaks the same language as you, but that's only likely to happen on a Macedonian-specific forum, not an international forum like Go4Expert. On international forums you can always safely assume the dominant language is English.
