ABSTRACT

Templates allow us to define generic class and function. So it supports generic programming. Generic programming is an approach where generic types are used as parameters in algorithms so that they work for a variety of suitable data types and data structures. A template can be used to create a family of classes or functions. For example, it can be used with class like student etc and it also can be used for function mul() etc. A template is also known as a kind of macro. Whenever template is created for any class it required substituted data types. Since template is define with a parameter for classes or functions so it is sometime called as parameterized classes or functions.

The main aim of this thesis is to show various ways to use template either with function or class.

INTRODUCTION

Template is one which supports generic class and function. So it supports generic programming. Generic programming is an approach where generic types are used as parameters in algorithms so it supports variety of suitable data types and data structures.

CLASS TEMPLATE

Following is syntax of class template. template class class-name { //………… // class members specification // with anonymous type T // whenever appropriate //………… };

As shown in syntax we can give any valid name in place of T. Now consider the following class, class student { int rno; public: void input() { coutrno; } void display() { cout

References Executive summary Introduction The aim of this report is to critically analyse the architecture of the website www.flinders.ed.au. The information gathered from the analysis will be used to devise solutions to problems with the website. The technique of examination for the website was to thoroughly explore the different pages of the website and grade each area of the website using appropriate criteria. Dave Gehrke (1999) states that” without efficient and user=friendly navigation, the user is likely to get confused, lost or frustrated and leave the site for good”. A resultant survey run by Gehrke (1999) showed that page loading speed and navigational efficiency are the most important things to users. The most important user type that needs to be happy with the website for it to be successful is prospective students as they make a majority of the people visiting the site. Prospective students are more likely to turn into current students if they like the feel of the website. This analyst took on the role of prospective student to test......

...kin31937_ch.02.qxd 10/23/06 2:06 PM Page 11 THESIS SENTENCE TEMPLATES A thesis sentence is a sentence in the introduction that tells the reader what the topic or argument of the essay is. Experienced writers have little difficulty writing thesis sentences. This is because they have read and written thousands of them. You, the emerging writer, don’t have it so easy. So, you have to accelerate the process. You do this via thesis sentence templates. A thesis sentence template is the basic machinery of a thesis sentence, what makes it work. It is like a car minus the hood, the doors, the engine, the side panels, the wheels, and the air conditioner. On that basic structure, thousands of different cars can be built. From a thesis sentence template, thousands of thesis sentences can be constructed. The introduction for any piece of writing is very important. This is where you establish a relationship with the reader. The introduction will always be read, while the body of the paper might sometimes be glossed over (not carefully read) by graders of standardized tests like the SAT® or TOEFL®. ? HOW THE THESIS SENTENCE TEMPLATES WORK Each type of thesis sentence presented in this section is followed by two or three examples of how very different thesis sentences can be written using the template. Then you will write two or three thesis sentences of your own using the template. If you find the template difficult, just do one sentence on your own. But the more......

Meeting Human Services Challenges with Technology

...Meeting Human Services Challenges with Technology Gina Sharra BSHS-351 January, 24th, 2011 Nate Hooper Meeting Human Services Challenges with Technology Technology has grown so much in the last decade that it is something that really should be used in the human services organizations today. It can help any of the organizations to not only grow with the demands that need to be met in human services, but it can also help the many services that are already being used or help to implement new technology uses that are not being used at this time for instance updating their systems. Technology can be used in many ways to benefit human services businesses, organizations as well as the non-profit services. There are so many different software’s that can be used to upgrade systems, add in systems that are old-school in which it will not only benefit these places in time management, privacy, HIPPA laws and in many other areas. One challenge for human services non-profit organization is it needs the proper tools to be able to provide its community with the services that are needed. But if they do not have the tools to get the information out into the community on what services they do provide than the community not only has no idea about this organization and what they provide, but the organization actually looses too because they themselves have no clientele. The different types of strategies that can help in this particular situation would be to add different ways for......

...recognition algorithms identify facial features by extracting landmarks, or features, from an image of the subject's face. For example, an algorithm may analyze the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These features are then used to search for other images with matching features. Other algorithms normalize a gallery of face images and then compress the face data, only saving the data in the image that is useful for face recognition. A probe image is then compared with the face data. One of the earliest successful systems is based on template matching techniques applied to a set of salient facial features, providing a sort of compressed face representation. Recognition algorithms can be divided into two main approaches, geometric, which looks at distinguishing features, or photometric, which is a statistical approach that distills an image into values and compares the values with templates to eliminate variances. Popular recognition algorithms include Principal Component Analysis using eigenfaces, Linear Discriminate Analysis, Elastic Bunch Graph Matching using the Fisherface algorithm, the Hidden Markov model, the Multilinear Subspace Learning using tensor representation, and the neuronal motivated dynamic link matching. 3-dimensional recognition A newly emerging trend, claimed to achieve improved accuracies, is...

Objects are created and eventually destroyed. Also during that lifetime, the attributes of the object may undergo significant change. class and object for same related methods class is nothing but same related to variable to methods. eg car is a class maruti santro bolero this is on object A Class is a template. An object is an instance of class. Every data member of an object contains its own value, where as Class only declares the data members. ------------------------------------------------------------------------------- What is the difference between class and structure? ->Structure: Initially (in C) a structure was used to bundle different type of data types together to perform a particular functionality. But C++ extended the structure to contain functions also. The major difference is that all declarations inside a structure are by default public. Class: Class is a successor of Structure. By default all the members inside the class are private. ------------------------------------------------------------------------------- What is encapsulation? ->Packaging an object?s variables within its methods is called encapsulation. itis protective wrapper which prevents the data from...
