sir i want to know which posting to apply since i am BE
CSE.. also want to know what are the rounds there for my
interview...Expecting for ur valuable answer....
write a code for this:trailer recordId contains a value
other than 99, then the file must error with the
reason ‘Invalid RECORD_ID’(User Defined Exception).

How to handle exception in c++,
For example in a functions i am assigning memory to some
variables and also in next instructions in am dividing one
variable also.
If this functions generates a error while allocating memory
to those variable and also while dividing the variable if i
divide by zero then catch block how it will identify that
this error has cone from perticular instruction
When is the last time you coded in C/C++? What is the most
lines of original C/C++ code you have personally written in
one project? How confident are you in your ability to write
C or C++ without a reference?

Question In a class, there is a reference or pointer of an
object of
another class embedded, and the memory is either allocated
or assigned to the new object created for this class. In
the constructor, parameters are passed to initialize the
data members and the embedded object reference to get
inialized. What measures or design change should be advised
for proper destruction and avioding memory leaks, getting
pointers dangling for the embedded object memory
allocation? Please suggest.

There is something to be taken care in destructor, in copy
constructor, suppose the memory is assigned to the embedded
member object pointer with the parameter passed value, but
if some other objects of different class also are pointing
to this memory, then if some one deletes the object then
this class member pointer object will become dangling, or
if the object is not deleted properly then there will be
memory leak. Please suggest the design change required to
handle or avoid this situation

how can i access a direct (absolute, not the offset) memory
address?
here is what i tried:
wrote a program that ask's for an address from the user,
creates a FAR pointer to that adress and shows it. then the
user can increment/decrement the value in that address by
pressing p(inc+) and m(dec-).
NOW, i compiled that program and opened it twice (in 2
different windows) and gave twice the same address to it.
now look what happen - if i change the value in
one "window" of the program, it DOES NOT change in the
other! even if they point to the same address in the memory!
here is the code snippet:
//------------------------------------------------------
#include <stdio.h> //INCLUDE EVERY KNOWN HEADER FILE
#include <conio.h> //FOR ANY CASE...
#include <iostream.h>
#include <dos.h>
#include <process.h>
main()
{
int far *ptr; //FAR POINTER!!!
long address;
char key=0; //A KEY FROM THE KEYBOARD
int temp=0;
clrscr();
cout<<"Enter Address:";
cin>>hex>>address; //GETS THE ADDRESS
clrscr();
(long)ptr=address; temp=*ptr; //PUTS THE ADDRESS IN THE PTR
cout<<"["<<hex<<(unsigned long)ptr<<"]="<<*ptr<<" = "<<
(char)(*ptr);
//SHOWS: [address]=value=ASCII symbol.
while (key!=27) //WHILE YOU DONT PRESS ESC.
{
while(!kbhit()) //WHILE KEY IS NOT PRESSED
{
if (temp!=*ptr) { temp=*ptr; clrscr(); cout<<"["<<hex<<
(unsigned long)ptr<<"]="<<*ptr<<" = "<<(char)(*ptr); };
//IF THE VALUE HAS CHANGED, CLEAR THE SCREEN AND SHOW
//AGAIN
if (key=='p') {key=0; (*ptr)++; } //INCREMENT VALUE
if (key=='m') {key=0; (*ptr)--; } //DEC. VALUE
};
key=getch(); //IF A KEY IS PRESSED, READ IT FROM THE
//KEYBOARD
};
return 0; //IF ESC WAS THE KEY, EXIT THE PROGRAM
}
