setget function in a template class

[YourSurrogateGod]

#include <iostream>
#include <iomanip>
using namespace std;

template <class T, int element>
class Array
{
public:
  void putElement(T x, int index);
  T getElement(int index);
  int &setgetInteger();

private:
  T item[element];
  int integer;
};

template <class T, int element>
void Array<T, element>::putElement(T x, int index)
{
  item[index] = x;
}

template <class T, int element>
T Array<T, element>::getElement(int index)
{
  return item[index];
}

template <class T, int element>
int Array<T, element>::setgetInteger()
{
  return integer;
}

int main()
{
  char *name[] = {"Meier", "Schulze", "Lehmann", "Aust"};
  double contents[]= {2200.5, 1300.5, 1700.30, 4888.80};

  Array<char *, 4> nameArray;
  Array<double, 4> contentsArray;

  nameArray.setgetInteger() = 56;

  for(int i = 0; i < 4; i++)
  {
    nameArray.putElement(name[i], i);
    contentsArray.putElement(contents[i], i);
  }

  for(i = 0; i < 4; i++)
  {
    cout << setiosflags(ios::left) << setw(10) << nameArray.getElement(i) 
         << resetiosflags(ios::left) << setw(8) << contentsArray.getElement(i) << endl;
  }

  cout << "Integer output: " << nameArray.setgetInteger() << endl;

  return 0;
}

This doesn't compile because of the setget function that I put in. My question is why can't I make it work with a specific value being returned? Is this a limitation of template classes or something? Sorry for the silly question, I'm just not familiar with this.

I've tried something like this ...

template <class T, int element, int integer>

... and making all of the appropriate changes along the way, but that still didn't work .

Maybe you tell us what the compiler error is first
By the way:

nameArray.setgetInteger() = 56;

This doesn't do anything but initializing an anonymous temporary variable with 56.

I think what you meant is that (note the reference type):

template <class T, int element>
int & Array<T, element>::setgetInteger()
{
  return integer;
}

Just as a side note.

I just recognized your declaration and definition of setgetInteger() don't fit. In the definition you return an int, in the declaration an int ref.

Yeh, fixed it. I need to get home asap, this is killing me to be so long abroad .

Ja, aber hast du irgendwann diese Fehler in CodeGuru geposted?
