my program

[femina]

with reference to your previos answer i jus tried a samll program but it has an error while compiling c++ eual.cpp
eual.cpp: In member function `bas bas::operator=(const bas&)':
eual.cpp:28: error: no matching function for call to `bas::bas()'
eual.cpp:22: note: candidates are: bas::~bas()
please help with the reaons behind this and also help me to solve this
#include<iostream>
using namespace std;
class bas{
int n;
public:
bas();
bas(const bas &ba);
bas operator=(const bas &r);
~bas();
};
bas::bas()
{
n=0;
cout<<"cons \n";
}
bas::bas(const bas &ba)
{
n=ba.n;
cout<<"ccons \n";
}
bas::~bas()
{
cout<<"des";
}
bas bas :: operator=(const bas &r)
{
if(this==&r) return *this;
bas::~bas();
this->n=r.n;
return *this;
}

main()
{
bas b;
bas b1;
b=b1;
}

Other than adding an int return type for main(), your code compiles and links witrh no errors using Visual Studio.NET 2005.
