Error Handling

[livesinabox]

So my Turbo C doesn't handle errors. And in school we used VC++ but I don't have it at home. So can anyone tell if the code snippets for Queue and Dequeuing a Queue and Pop and Push operations in Stack are right?

\int queue::dequeue()
{
try
{
if(front>rear)
throw 0;
}
catch(int)
{
cout<<"queue is empty\n";
return 0;
}
return a[rear];
}

void queue::enqueue(int ch)
{
try
{
if(cap==size)
throw size;
}
catch(int)
{
cout<<"queue is full\n";
return;
}
a[++rear]=ch;
size++;
}

void stack::push(int op)
{
try
{
if(top==SIZE)
throw top;
}
catch(int)
{
cout<<"Stack is Full \n";
return;
}
++top;
stck[top]=op;
}
int stack::pop()
{
try
{
int(top==0)
throw 0;
}
catch(int)
{
cout<<"Stack is Empty!\n";
return 0;
}
top--
return stck[top];
}

yeah, it would work!!!!!

But try using exception hierarchy in future.....it is more elegant, easy for complex problems

Why not? The express version is free for the asking (downloading). Would you build an engine for a 50 year-old car and expect it to work on a 2010 model?
