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 generates a jump to the function. At the end of the function it jumps back

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, when used correctly this technique can be surprisingly powerful. Recursion is much easier to understand with an example than with lengthy explanations,

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 all time. Why? “It’s a miracle device,” he said. “It keeps hot things hot, but cold things it

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 to, less than, and greater than. The result of the comparison is true or false;

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,

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.
