Write a program to compute for numeric grades for a course.
The course records are in a file that will serve as the
input file. The input file is in exactly the following
format: Each line contains a student's first name, then one
space, then ten quiz scores all on one line. The quiz scores
are in whole number and are separated by one space. Your
program will take it input from this file and sends it
output to a second file. The data in the output file will be
exactly the same as the data in the input file except that
there will be one additional number (of type double) at the
end of each line. This number will be the average of the
student's ten quiz scores. Use at least one function that
has file streams as all or some of its arguments.

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.

Answer # 1 use copy constructors 0 Shanthila 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
