write a program for conversion from decimal to binary ,octal and hexadecimal .the program should be developed as follows:

(a).the base class convert has two variables initial and result in which initial is a number before conversion and result is 

after conversion.

(b). it has two member functions getinit() and getconv() which return the initial value and converted value respectively.

(c). write a function compute which is a pure virtual function that actually does the conversion.

(d). separate derived classes for hexadecimal ,binary, octal, does the conversion by implementing the function compute.

(e). create the objects for each class using new operator.

(f). use the convert class type pointer to call the compute functions of the derived classes.

write a program to copy content of one file to another file in c++

Create a person class with name as data member provide four functions in getname() to get input from user and put name to display output write two virtual functions getdata() and outstanding() where both these functions takes no argument and getdata() returns no value but outstanding() returns Boolean value . Derive student and professor from person. student class should contain gpa as its float type and overrides the virtual functions appropriately . In professor class provide number of applications as data members and override the virtual functions appropriately . Write a main program to declare a array of pointers to person object and depending on the choice from user create either a student object or professor object and store it in person array for n persons and display the details along with whether the person is outstanding or not

Write a program to create a numeric file and split the file into two files, one containing all odd

numbers and another with even numbers.

create a class Matrix the stores it in a safe 2D array .that is it it should check for array index bounds .a constructor should allow the programmer to specify the actual dimensions of the matrix. define number functions : putel() for taking 3 argument row index , column index and the element storing it in the corresponding location. getel() for taking 2 arguments row and column indexes and returns the elements from that location . overload the operators +,-,and * appropriately

create a person class with name as it's data member . provide 4 functions getname() to get input from user and putname() to display output. Write two virtual functions getdata() and outstanding() where both these functions takes no argument and getdata() returns no value but outstanding () returns a Boolean value. Derive student and professor from person. student class should contain GPA as its float type data member and overrides the virtual functions appropriately .in professor class provide number of publications as data member and overrides the virtual functions appropriately. write a main program to declare an array of pointers to person object and depending on the choice from user create a student object or professor object and store it in person array for n persons. display the details along with whether the person is outstanding or not
