C++ offers several ways to shorten and clarify your code. One of these is the arithmetic assignment operators. This operator helps to give C++ listings their distinctive appearance. The following kind of statement is common in most languages. total = total + item; // adds “item” to “total” In this situation you add something to

In any language C++ programming basics there are some fundamentals you need to know before you can write even the most elementary programs. This chapter introduces three such fundamentals: basic program construction, variables, and input/output (I/O). It also touches on a variety of other language features, including comments, arithmetic operators, the increment operator, data conversion,

C++ is derived from the C language. Strictly speaking, it is a superset of C: Almost every correct statement in C is also a correct statement in C++, although the reverse is not true. The most important elements added to C to create C++ concern classes, objects, and object oriented programming. (C++ was originally called

Let’s briefly examine a few of the major elements characteristics of object oriented programming languages in general, and C++ in particular. Objects When you approach a programming problem in an characteristics object oriented programming language, you no longer ask how the problem will be divided into functions, but how it will be divided into objects.

Object oriented programming was developed because limitations were discovered in earlier approaches to programming. To appreciate what object oriented programming does, we need to under stand what these limitations are and how they arose from traditional programming languages. Procedural Languages C, Pascal, FORTRAN, and similar languages are procedural languages. That is, each statement in the

What is an array? An array is defined as an ordered set of similar data items. All the data items of an array are stored in consecutive memory locations in RAM. The elements of an array are of same data type and each item can be accessed using the same name. How to declare and

A dearearator is a device widely used for the removal of air and other dissolved gases from the feedwater to steam generating boilers. In particular, dissolved oxygen in boiler feed waters will cause a serious corrosion damage in steam systems by attaching to the walls of metal piping and other metallic equipment and forming oxides

What is Virtual Function? Virtual means existing in appearance but not in reality. When virtual functions are used, a program that appears to be calling a function of one may in reality be calling a function of a different class. Why are virtual functions needed? Suppose you have a number of objects of different classes

A boiler which generates steam at pressure greater than 80bar, a temperature of about 500°C, producing, steam more than 250 tons per hour called high pressure boilers. By using high pressure boilers, low grade fuels can be burned easily. High pressure boilers are water tube boilers and use pulverized coal firing. Examples of these boilers
