C++ programming tutorial basic concepts - { UPPOG2 }

Introducing C++

(pronounced "see plus plus") is a general-purpose, statically typed, free-form, multi-paradigm programming language supporting procedural programming, data abstraction, and generic programming. If these concepts are unfamiliar, do not worry, they will be introduced in subsequent sections. During the 1990s C++ grew to become one of the most popular computer programming languages. Today C++ remains high on the Tiobe rankings.

Why learn C++ ?

Why not? This is the most clarifying approach to the decision to learn anything. Although learning is always good, selecting what you learn is more important as it is how you will prioritize tasks. Another side of this problem is that you will be investing some time in getting a new skill set. You must decide how this will benefit you. Check your objectives and compare similar projects or see what the programming market is in need of. In any case, the more programming languages you know, the better.

C++ is not the ideal first language. However, if you are willing to dedicate a more than passing interest in C++, then you can even learn it as your first language. Make sure to dedicate some time understanding the different paradigms and why C++ is a multi-paradigm, or hybrid, language.

If you are approaching the learning process only to add another notch under your belt, that is, willing only to dedicate enough effort to understand its major quirks and learn something about its dark corners, then you would be best served in learning two other languages first. This will clarify what makes C++ special in its approach to programming. You should select one imperative and one object-oriented language. C will probably be the best choice for the former, as it has a good market value and a direct relation to C++, although a good substitute would be ASM. For the latter, Java is a good choice, mostly because it shares much of its syntax with C++ but it does not support imperative programming. Read the language comparison section for better understanding the relations.

Although learning C is not a requirement for understanding C++, you must know how to use an imperative language. C++ will not make it easy for you to understand some of these deeper concepts, since in it you, the programmer, are given the greater range of freedom. There are many ways of doing things in C++. Understanding which options to choose will become the cornerstone of mastering the language.

You should not learn C++ if you are solely interested in learning Object-oriented Programming. C++ offers some support for objects, but is still not truly Object-oriented, and consequently the nomenclature used and the approaches taken to solve problems will make it more difficult to learn and master those concepts. If you are truly interested in Object-oriented programming, you should learn Smalltalk.

As with all languages, C++ has a specific scope of application where it can truly shine. C++ is harder to learn than C and Java but more powerful than both. C++ enables you to abstract from the little things you have to deal with in C or other lower level languages but will grant you more control and responsibility than Java. As it will not provide the default features you can obtain in similar higher level languages, you will have to search and examine several external implementations of those features and freely select those that best serve your purposes
