INTRODUCTION OF METHOD

Classes usually consist of two things instance variables and methods.

Methods are defined as follows:

· Return type

· Name of the method

· A list of parameters

· Body of the method.

Syntax:

return type method name (list of parameters)

{

//Body of the method

}

return type specifies the type of data returned by the method. This can be any valid data type including class types that you create. If the method does not return a value, its return type must be void, Means you can say that void means no return. Methods that have a return type other than void return a value to the calling routine using the following form of the return statement:

return value;

The list of parameter is a sequence of type and identifier pairs separated by commas. Parameters are essentially variables that receive the value of the arguments passed to the method when it is called. If the method has no parameters, then the parameter list will be empty.

Class which have methods and data members both

Standard and Formatted Input / Output in C++

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called input operation and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called output operation . Standard Input and Output in C++ is done through the use of streams . Streams are generic places to send or receive data. In C++, I/O is done through classes and objects defined in the header file <iostream> . iostream stands for standard input-output stream. This header file contains definitions to objects like cin , cout , etc. /O Library Header Files There are...

Genetic Algorithm: Population, Fitness Function, Parent Selection, Cross over, Mutation

Genetic Algo Population Population is a subset of solutions in the current generation. It can also be defined as a set of chromosomes. There are several things to be kept in mind when dealing with GA population − The diversity of the population should be maintained otherwise it might lead to premature convergence. The population size should not be kept very large as it can cause a GA to slow down, while a smaller population might not be enough for a good mating pool. Therefore, an optimal population size needs to be decided by trial and error. The population is usually defined as a two dimensional array of – size population, size x, chromosome size . Population Initialization There are two primary methods to initialize a population in a GA. They are − Random Initialization − Populate the initial population with completely random solutions. Heuristic initialization − Populate the initial population using a known heuristic for the problem. It has been observed that the e...

Normalization in DBMS: 1NF, 2NF, 3NF and BCNF in Database

Normalization is a process of organizing the data in database to avoid data redundancy, insertion anomaly, update anomaly & deletion anomaly. Anomalies in DBMS There are three types of anomalies that occur when the database is not normalized. These are – Insertion, update and deletion anomaly. Let’s take an example to understand this. Example : Suppose a manufacturing company stores the employee details in a table named employee that has four attributes: emp_id for storing employee’s id, emp_name for storing employee’s name, emp_address for storing employee’s address and emp_dept for storing the department details in which the employee works. At some point of time the table looks like this: emp_id emp_name emp_address emp_dept 101 Nikhil Kangra D001 101 Nikhil Kangra D002 123 Ashish Shimla D890 166 Rahul Pathankot D900 166 Rahul Pathankot D004 The above table is not normalized. Update anomaly : In the above table we have two rows for employee Nikhil as he belongs ...
