Overloading binary operators can be overloaded just as easily as unary operators. We’ll look at examples that overload arithmetic operators, comparison operators, and arithmetic assignment operators. Arithmetic Operators In the...

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...
A const member function guarantees that it will never modify any of its class’s member data. The CONSTFU program shows how this works. //constfu.cpp //demonstrates const member functions / class aClass { private: int...
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...
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...
