Having said that each object contains its own separate data, we must now amend that slightly. If a data item in a class is declared as static, only one such item is created for the entire class, no matter how many objects there...

We’ve seen two ways to initialize objects. A no-argument constructor can initialize data members to constant values, and a multi argument constructor can initialize data members to values passed as arguments. Let’s mention...
It is the sheet metal operations of production of a hole in a sheet metal by the punch and die. In case of punching, a circular hole is produced, where as in the case of piercing, the hole produced may be of any...
To deform the metal permanently, the stress must exceed the elastic limit. At room temperature, the metal is in a more rigid state than when at higher temperature. Hot Working and Cold Working Metal Forming. Thus, to deform the...
In many programming situations, objects in programs represent C++ Objects as Physical Objects: things that can be felt or seen. These situations provide vivid examples of the correspondence between the program and the real world...
We mentioned that inline function save memory space because all the calls to the function cause the same code to be executed; the function body need not be duplicated in memory. When the compiler sees a function call, it normally...
The existence of functions makes possible a programming technique called recursion. Recursion c++ involves a function calling itself. This sounds rather improbable, and indeed a function calling itself is often a bug. However...
An overloaded functions appears to perform different activities depending on the kind of data sent to it. Overloading is like the joke about the famous scientist who insisted that the thermos bottle was the greatest invention of...
A relational operators compares two values. The values can be any built in C++ data type, such as char, int, and float, or as we’ll see later they can be user defined classes. The comparison involves such relationships as equal...
Investment Types of Casting Process It can cast very thin and complex features It offers excellent surface finish It offers excellent dimensional accuracy Can be used to cast all metals and alloys Investment Casting –...
