class definition without a private section

[kyleg033]

Can anybody help walk me through this? This is my homework for an entry level Computer Science Class. I have no idea where to start. Any advice? I'm not looking for the answer, I am trying to understand these concepts and the tutoring center in my school is closed so you guys are my only hope!



Class interface implied by client code:

Write the class definition, without a private section (as you cannot tell what would be in it), implied by the following client code. That is, create a class definition with an interface required to implement the following code.

Baz foo(const Baz& tex)
{
Baz* var = new Baz(5, "This is fun!");

tex.set("This string.");
for (int i = tex.howMany(); i < Baz::MAX; ++i)
{
doc->write();
} // end for

return *doc;
} // end func

Use CODE tags...

Here the structure of a class definition...

class AValidClassNameHere
{
public:
    //This area is for public functions/methods
   // This area is also for public variables

private:
   //This area is for private functions/methds
   //This area is also for private variables
};

Now you need to fill in the important stuff like functions and variables.

See here aswell...

http://cplusplus.com/doc/tutorial/classes2/

Your code:

Baz foo(const Baz& tex)
{
   Baz* var = new Baz(5, "This is fun!");

   tex.set("This string.");
   for (int i = tex.howMany(); i < Baz::MAX; ++i)
   {
       doc->write();
   } // end for

   return *doc;
} // end func 

I am unclear on the statement, is the foo function to wrapped in a class or are you to define the Baz class? If the Baz class... then look for all the function/method calls. Look for all the member variables. Create the class definition. i.e.

class AValidClassNameHere
{
public:
    //This area is for public functions/methods
   // This area is also for public variables
   int SomeFunctionNameHere(int someParameterHere);
   
   float SomeMemberVariableHere;
private:
   //This area is for private functions/methds
   //This area is also for private variables
};

Thanks for the help! That was a perfect explanation!

Post your work, and I'll help you if you still have problems. Its not overly tough, but it is a good learning assignment (however unusefule the code actually is).

woah woah woah

Baz foo(const Baz& tex)
{
   Baz* var = new Baz(5, "This is fun!");

   tex.set("This string.");
   for (int i = tex.howMany(); i < Baz::MAX; ++i)
   {
       doc->write();
   } // end for

   return *doc;
} // end func  

A few things:

1) Why are you making 'var' and then never using it?
2) Where did 'doc' come from? Was 'doc' supposed to be 'var'?
3) You have a memory leak. You're making 'var' with new, but you're never deleting it.

Disch, it is a homework assignment given by a teacher to try to get the student to understand the different methods and member variables used with classes. I.e. constructor. Its not a useful code example by any other means.
