PHASE III

FUNCTION OVERLOADING:

Q 1. Write a program that use function overloading to do the following task-

n  Demonstrate the exact match

n  Demonstrate the integral promotion

n  Demonstrate the ambiguity error

n  Demonstrate the concept of default arguments along with function overloading

Q2. Write a program that use function overloading to do the following task-

n  Find the max. of two numbers

n  Find the max of three numbers

Q3. Write a program that use function overloading to do the following task-

n  Compute xy , where x and y both are of int type. 

n  Compute xy,  where x is float type and y is int type.

Q4. Write a C++ program to create a class called COMPLEX and implement the following overloading functions ADD that return a complex number:

a. ADD(a, s2) – where ‘a’ is an integer (to be added to real part only) and s2 is a complex number

b. ADD(s1, s2) – where s1 and s2 are complex numbers

c. ADD(s1, a) – where ‘a’ is an integer (to be added to real part as well as imaginary part) and s1 is a complex number

Q5. Demonstrate the concept of function overloading among the classes by designing three classes Square, Rectangle, & Circle. All the three classes must have functions getdata(), calc_area(), disp();

Operator Overloading

Q6. Write a complete definition for an overloaded + , - , * operator for the INTEGER class. It should add 2 INTEGER objects. It can solve the following expressions:

A=B*C

A=B*8;

A=B+C-D

A=B-C*D/E

Q7 A class Clock has following members:

Data members:

            Hour of type integer

            Minute of type integer

Second  of type integer

Member function:

            Readtime (int h, int m, int s);

            Showtime ();

            addTime(Clock);

addTime(Clock,Clock);

Write a complete program in C++ to input two different objects FT, ST. Print their sum (assuming 24 hour clock time) by overloading the + operator for class Clock

Q8. Write a complete definition for an overloaded + , - , * operator for the COMPLEX class. It should add 2 COMPLEX objects. It can solve the following expressions:

A=B*C

A=B+C

A=B*8;

A=A*B+C-5*D+8

A=8*B;

If some operation is not possible, mention the reason.

Q9. WAP to add one INTEGER with one FLOAT object, using overloading binary + operator using friend function for FLOAT class and member function for INTEGER class.

Q10. WAP to overload += operator overloading.

Q11. WAP to overload ++ operator overloading.(prefix & postfix)

Q12. WAP to overload -- operator overloading. (prefix & postfix)

Q13. WAP to overload == operator overloading.

Q14. WAP to overload << operator overloading.

Q15. WAP to overload >> operator overloading.
