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

Why can't we have instance(stack) of a class as a member of
the same class like eg.Class A{A obj;} as we can have self
refential pointer

I want to write a C++ language program that:
1. Reads in the size of a square from the screen;
2. Prints a hollow square of that size out of “-“, “|” and
blanks on screen;
3. Prints the same hollow square onto a text file.
The program should work for squares of all side sizes
between 1 and 20.

Am studying basic c++ programming, have been given the
following assignment. Design a linear program to calculate
the maximum stress a material can withstand given a force
and a diameter of a circle. To find the required area pi
should be defined.
Have most of the program sorted out but am at a loss as to
how to show the calculations required. Can anyone help?
write a code for this. serial_number contained in the
header of the file will be read , if this serial number is
less than a previous serial number within a successfully
processed file, or is the same as another serial number
within a successfully processed file, or if the field
contains anything other than 7 digits, then the file must
error with the reason ‘Invalid SERIAL_NUMBER’.
