Hi,
I have a query related to exceptional handling. I pasted the code I tried
following this mail.
My intention is , what happens in a sistuation when any exception is caught in
main , so while destructing the objects till that instant again if any
exception is caught (stack unwinding concept).
similary in constructor. For constructor I know that the desctructors of the
sub objects will be called . But how that exception is handled .
#include<stdio.h>
#include<conio.h>
#include<iostream>
using namespace std;
class var1
{
public:
var1()
{
cout<<"I m in var1 conc"<<endl;
}
~var1()
{
cout<<"I m in var1 desc"<<endl;
}
};
class MyCls
{
public:
var1 *obj;
MyCls():obj(NULL)
{
obj=new var1();
cout<<"I m in cons"<<endl;
}
~MyCls()
{
cout<<"I m in desc"<<endl;
throw "excepto";
delete obj;
cout<<"Deleted obj"<<endl;
}
};
void main()
{
try
{
MyCls obj;
cout<<"Obj Created"<<endl;
throw "error";
cout<<"Obj after throwing err"<<endl;
}
catch(char *x)
{
cout<<x<<endl;
}
catch(...)
{
cout<<"I m in last"<<endl;
}
}

I don't think Turbo C supports exceptions. You need to upgrade to a
modern compiler like Dev-C++ or MS Visual C++ Express (they are free)
and not use something that is 15+ years old.
