Let’s start off by overloading a unary operators. unary operators act on only one operand. (An operand is simply a variable acted on by an operator.) Examples of unary operators are the increment and decrement operators ++ and –, and the unary minus, as in -33. “Objects and Classes,” we created a class Counter to

We noted at the beginning of this chapter that two kinds of strings are commonly used in C++: C-strings and strings that are objects of the string class. In this section we’ll describe the first kind, which fits the theme of the chapter in that C-strings are arrays of type char. We call these strings

We’ve seen how an object can contain an array. We can also reverse that situation and create an arrays of objects. We’ll look at two situations: an array of English distances and a deck of cards. Arrays of English Distances “Objects and Classes,” we showed several examples of an English Distance class that incorporated feet

In this part we discuss mobile robots, a class of robots that are able to move through the environment. The figures show an assortment of mobile robots that can move over the ground, over the water, through the air, or through the water. This highlights the diversity of what is referred to as the robotic

The term introduction of robot means different things to different people. Science fiction books and movies have strongly influenced what many people expect a robot to be or what it can do. Sadly the practice of robotics is far behind this popular conception. One thing is certain though robotics will be an important technology in

A Diesel power plant (also known as Stand by diesel power station) uses a diesel engine as prime mover for the generation of electrical energy. This power station is generally compact and thus can be located where it is actually required. This kind of power station can be used to produce limited amounts of electrical

An agile process reduces the agility and cost of change because software is released in increments and change can be better controlled within an increment. Agility argue that a well designed agile process “flattens” the cost of change curve shown in following figure, allowing a software team to accommodate changes late in a software project

The best software process is personal and team process model one that is close to the people who will be doing the work. Watts Humphrey proposed two process models. Models “Personal Software Process (PSP)” and “Team Software Process (TSP).” Both require hard work, training, and coordination, but both are achievable. Personal Software Process (PSP) The

Unified process (UP) is an architecture centric, use case driven, iterative and incremental development process. UP is also referred to as the unified software development process. The Unified Process is an attempt to draw on the best features and characteristics of traditional software process models, but characterize them in a way that implements many of

Component Based Development The component based development model incorporates many of the characteristics of the spiral model. It is evolutionary in nature, Specialized process model demanding an iterative approach to the creation of software. However, the component based development model constructs applications from prepackaged software components. Modeling and construction activities begin with the identification of
