🟢 Topic ➡ Operator Overload And Friend Function


01. Define a class Complex with appropriate instance variables and member functions.
Define following operators in the class :-
- a. +
- b. -
- c. *
- d. ==

02. Write a C++ program to overload unary operators that is increment and decrement.

03. Write a C++ program to add two complex numbers using operator overloaded by a
friend function.

04. Create a class Time which contains hours,minutes and seconds as data members. Write a C++ program using operator overloading for the following :-
1. == : To check whether two Times are the same or not.
2. >> : To accept the time.
3. << : To display the time.

05. Consider following :-
class Numbers
{
  int x,y,z;

};
Overload the operator unary minus (-) to negate the numbers.

06. Create a class CString to represent a string and define following
a. Overload the + operator to concatenate two strings.
b. == to compare 2 strings.

07. Define a class fraction
class Fraction
{
  long numerator;
  long denominator;

  Public:
  fraction (long n=0, long d=0);
};
Overload the following operators as member or friend:
a. Unary ++ (pre and post both)
b. Overload as friend functions: operators << and >>.

08. Consider a class Matrix
Class Matrix
{
     int matrix[3][3], rows = 3, cols = 3;
};
Overload the - (Unary) should negate the numbers stored in the object.

09. Consider the following class mystring
Class mystring
{
  char str [100];
};
Overload operator “!” to reverse the case of each alphabet in the string (Uppercase to Lowercase and vice versa).

10.Class Matrix
{
  int matrix[3][3],rows=3,cols=3;
};
Let m1 and m2 are two matrices. Find out m3=m1+m2 (use operator
overloading).

11. Define a class Complex with appropriate instance variables and member functions.
Overload following operators
a. << insertion operator
b. >> extraction operator

12. Overload subscript operator [] that will be useful when we want to check for an index
out of bound.

13. Create a student class and overload new and delete operators as a member function
of the class.

14. Create a student class and overload new and delete operators using friend function.

15. Create a complex class and overload assignment operator for that class.

16. Create an Integer class and overload logical not operator for that class.

17. Create a Coordinate class for 3 variables x,y and z and overload comma operator
such that when you write c3 = (c1 , c2 ) then c2 is assigned to c3. Where c1,c2,and
c3 are objects of 3D coordinate class.

18. Create an Integer class that contains int x as an instance variable and overload
casting int() operator that will type cast your Integer class object to int data type.

19. Create a Distance class having 2 instance variable feet and inches. Also create
default constructor and parameterized constructor takes 2 variables . Now overload ()
function call operator that takes 3 arguments a , b and c and set feet = a + c + 5 and
inches = a+b + 15.

20. Create a class Marks that have one member variable marks and one member
function that will print marks. We know that we can access member functions using
(.) dot operator. Now you need to overload (->) arrow operator to access that
function.
