C++ difficulty

Hello I have a problem with this task at the moment:

A concert agency wants to manage their events to introduce a new computer system.
It is an event by means of a structure and all events are described
Events of the Agency as a linked list of events.
program
- A function void output (...)
which shows the data of an event on screen. The parameters can be suitably
be elected
- A function void output list (Event * start)
which, as all events of the list on the screen indicating the first element
This parameter is passed.
Test the functions using a suitable driver. Here, a list of
at least 4 concatenateded events are fixed (no need to read).
Other functions can be added as needed.
As a second project team to design the structure of event involved, you need to
Development first implement a simple prototype for this. as
Minimum requirement should be the prototype next to the pointer to the next element
- A description of the event
- The number of available seats
- The number of unsold seats
included.

I have problems at the moment in the beginning.


How should I define the function void output?

I hope somebody can help me.

And do you also have an idea how I can do this:

- A function void output list (Event * start)
which, as all events of the list on the screen indicating the first element
This parameter is passed.

How should I define this function?

Sorry I have a little problem with this task , that `s why I am asking.

How can I show the first element as a parameter?

if event is a datatype, use this:

1
2
3
4
 
void output_list(Event *start)
{
    /*your code here*/
}

#include <iostream>

using namespace std;

int main()
{
    void output(int a; int b; int c;)
{
    for(from start to end of all parameters
   {
       std::cout << parameter[i];
   }
   void output_list(Event *start)
{
    
    
}
}
}






void Output( /* Whatever parameters here*/ )
{
// Code that shows data of event
}



Can somebody tell me which kind of events I could take ?

That would me help a lot.

I'm assuming your Event class has a container member. Just output that container.
Casey21 (25)
What do you mean by container member?

Which container should I output?
ResidentBiscuit (3106)
Well I don't know, I have no idea what the Event class looks like.
Casey21 (25)
Is atleast my output now right?

{
    int a = theater;
    int b = seats;

    int c = unsolved seats;


    for(from start to end of all parameters
   {
       std::cout << parameter[i];
   }
   void output_list(Event *start)
{


}
}
}


Or when there is a mistake , how can I correct it?

{
    void output(int a; int b; int c;) //cant declare function in another function. Parameter list is separated by commas, no semi colons.
{
    int a = theater; //What is theatre? What is seats? None of these are defined as far as I can tell
    int b = seats;

    int c = unsolved seats;


    for(from start to end of all parameters   //This isn't actually anything. It's an example for you to base off of. People expect you to be able to write something yourself.

       std::cout << parameter[i];

   void output_list(Event *start)

Casey21 (25)
Oh sorry. I have a little difficulty with programming and not so much idea like you people

How can I define seats and theatre?

You're allowed to declare a function within a function, but you cannot give it a body. For instance:

1
2
3
4
5
6
7
8
9
 
int main( )
{
    int SomeFunction( );
}

int SomeFunction( )
{
    // Some code that I hope is worth typing.
}

I don't know if you knew that already, though :)

Can you show me how the code of the first function should be than I can try the other function myself?

Because I have problems in the beginning so that I cant really start with the task.

I would be really thankful for that.

Are you sure? I've never heard this before, and it wouldn't make any sense.
Casey21 (25)
I have nö idea that's why I am asking.


Can please someone help me ?
ResidentBiscuit (3106)
People have already told you how to get started, yet you haven't shown anything of your own yet.

After reading this, output_list() gets passed in the first node of a linked list. All you need to do is output the relevant information, move on to the next node, and repeat until you hit the last node.

I'm 100% sure. Declaring functions within another functions may seem like nonsense, but declaring function in such a way has its uses, however.

ResidentBiscuit (3106)
Well now you've sparked my curiosity. Why would this ever be useful? The only thing I can think of is to limit the scope of it, but why have a function that can only be used by one specific other function? And if you can't place the body of the function with it, where does that go?
