canteen-management-system
The main objective of this project is to manage the details of canteen Employee ,Item, Stock and Sales . It manages all the information about the canteen customer and sales The object is totally built at administration end and thus only the administrator is guaranteed the access . The purpose of the project to build an application program to reduce the manual work for managing the Canteen , Employee, Customer and Items . It tracks all the details about the items , stock and sales
QUIZ-USING-MULTITHREAD-
ABSTRACT Modern education system includes conducting various activities. Exams are the most traditional method among that. Even in that traditional method for testing knowledge of students, technology has made it easier. In all the fields such as government exams and many exams are conducted online. We built a program to conduct these tests. The main intention of this project is to build Quiz app using multithreading. This project makes use of multithreading and java swing concepts. The built app is user friendly, easy to use and very helpful in schools and universities.
-this-Pointer-in-cpp
this’ pointer, it is important to know how objects look at functions and data members of a class.
Access-Specifiers-in-Cpp
In C++, there are three access specifiers: • public - members are accessible from outside the class • private - members cannot be accessed (or viewed) from outside the class • protected - members cannot be accessed from outside the class, however, they can be accessed in inherited classes.
Array-of-Objects-in-cpp
To print the area of two rectangles having different dimensions, create two objects of the Rectangle class, each representing a rectangle. Before moving to the concept of array of objects, let's first see an example of printing the area of two rectangles. The syntax for declaring an array of objects is class_name array_name [size] ;

Catching-class-Type-Exceptions-in-cpp
An exception can be of any type, including class types that you create. Actually, in real-world programs, most exceptions will be class types rather than built-in types. Class type exception is defined so as to create an object that describes the error that occurred. This information can be used by the exception handler to help it process the error. For example
Classes-Objects-in-C-
A class is a blueprint for the object. A class is defined in using keyword class followed by the name of class. Class binds the data and its associated functions together. Class has two specifications: 1. Class declaration 2. Class function definations
Constructors-in-cpp
A constructor is a member function of a class which initializes objects of a class. In C++, Constructor is automatically called when object(instance of class) create. It is special member function of the class. How constructors are different from a normal member function? 1. Constructor has same name as the class itself 2. Constructors don‟t have return type 3. A constructor is automatically called when an object is created. 4.If we do not specify a constructor, C++ compiler generates a default constructor for us (expects no parameters and has an empty body).

Destructors-in-cpp
Destructor is a member function which destructs or deletes an object.
Exceptions-in-cpp
An exception is a problem that arises during the execution of a program. A C++ exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero.
Friend-Function-in-cpp
Like friend class, a friend function can be given special grant to access private and protected members. A friend function can be: a) A method of another class b) A global function Eg: class Node { private: int key; Node *next; /* Other members of Node Class */ friend int LinkedList::search(); // Only search() of linkedList // can access internal members };
Function-overriding-in-cpp
�Function overriding is a feature that allows us to have a same function in child class which is already present in the parent class. A child class inherits the data members and member functions of parent class, but when you want to override a functionality in the child class then you can use function overriding. It is like creating a new version of an old function, in the child class.
Function-templates-in-cpp
•Function templates are special functions that can opera te with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. •In C++ this can be achieved using template parameters. A template parameter is a special kind of parameter that can be used to pass a type as argument: just like regular function parameters can be used to pass values to a function, template parameters allow to pass also types to a function. These function templates can use these parameters as if they were any other regular type. The format for declaring function templates with type parameters is: template <class identifier> function_declaration; template <typename identifier> function_declaration; only difference between both prototypes is the use of either the keyword class or the keyword typename
Inheritance-in-cpp
In C++, inheritance is a process in which one object acquires all the properties and behaviours of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviours which are defined in other class.
Member-Functions-in-Classes
There are 2 ways to define a member function: 1.Inside class definition 2.Outside class definition To define a member function outside the class definition we have to use the scope resolution :: operator along with class name and function name. Note: All the member functions defined inside the class definition are by default inline.
Multiple-catch-Statements-in-cpp
There can be more than one catch block for a single try block. Each catch must catch a different type of exception. For example, this program catches both integers and strings.
Polymorphism-in-cpp
Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions.
Pure-Virtual-functions
�A pure virtual function (or abstract function) in C++ is a virtual function for which we don’t have implementation, we only declare it. A pure virtual function is declared by assigning 0 in declaration. �A pure virtual function is implemented by classes which are derived from a Abstract class.

So swapping two numbers using pointers means we are using call by reference method. Swap two numbers without using third variable . Swap two numbers using third variable .
The-diamond-problem-in-cpp
�The diamond problem The diamond problem occurs when two super classes of a class have a common base class. For example, in the following diagram, the TA class gets two copies of all attributes of Person class, this causes ambiguities.
