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

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
