Some thoughts about programming language tutorials and books. First, I want to welcome you to "Computer Science for Everyone". I made this course in the hopes that those who are seeking to learn programming would be able to. I realize that this is a complex topic, and it may seem overwhelming at first. Once you learn this skill, you will have many opportunities open to you that were not open before. You may be able to get a better job, or perhaps even to create your own product and start your own company. At the very least, you will have access to far more tools that will enable you to do more than you could do before.
The C++ 'const' Declaration: Why & How The 'const' system is one of the really messy features of C++. It is simple in concept: variables declared with ‘const’ added become constants and cannot be altered by the program. However it is also used to bodge in a substitute for one of the missing features of C++ and there it gets horridly complicated and sometimes frustratingly restrictive. The following attempts to explain how 'const' is used and why it exists. Simple Use of ‘const’ The simplest use is to declare a named constant. Fear the Beard: Everything You Ever Wanted to Know About Facial Hair (Infographic) Ever wonder if growing facial hair has a purpose beyond making it easier to play “Spot the Hipster” at trendy urban coffee houses? Apparently it does. While modern may might grow a beard to intimidate opposing batters, prehistoric men grew beards to keep warm, intimidate enemies and protect their faces from punches. Plus, ancient civilizations saw beards as a sign of honor, and women today — while admitting they find bearded men to be 67% as attractive as clean shaven men — consider guys with full facial hair to be more respected, powerful and of higher status.

The Earth – and Its Average Inhabitant – at 7 Billion People (Infographic) According to the U.N. Population Fund, on October 31, 2011, the earth became home to 7 billion people. And the population is growing quickly. Estimates put the planet at 8 billion in another 14 years, which is an eye blink compared to the 123 years it took us to go from 1 billion to 2 billion. Mobile Computing with iPhone and Android The dates for each paper presentation are listed below. For each paper, a student or group of students will be asked to present the paper. The presentation should present a technical overview of the paper and argue the merits and flaws of the paper.
guide-to-advanced-programming-in-C C language is language of choice for systems programming, embedded systems and also viable option for many other applications. While it is not likely to have serious interest in computer programming and not to be touched by C, it is extremely challenging to understand all its aspects and shady corners. This article attempts to provide dense material to illuminate some of those areas. Namely: integer promotions, memory allocation, array to pointer conversions, explicit inlining, interpositioning and vector conversions. Diamond problem Details Multiple inheritance allows programmers to use more than one totally orthogonal hierarchy simultaneously, such as allowing Cat to inherit from Cartoon character and Pet and Mammal and access features from within all of those classes. The widespread view that multiple inheritance is “bad” or “dangerous” is not justified; most of the time, it results from experience with imperfect multiple inheritance mechanisms, or improper uses of inheritance. Well-applied multiple and repeated inheritance is a powerful way to combine abstractions, and a key technique of object-oriented software development. Implementations
What is an Operating System Not all computers have operating systems. The computer that controls the microwave oven in your kitchen, for example, doesn't need an operating system. It has one set of tasks to perform, very straightforward input to expect (a numbered keypad and a few pre-set buttons) and simple, never-changing hardware to control. For a computer like this, an operating system would be unnecessary baggage, driving up the development and manufacturing costs significantly and adding complexity where none is required. Instead, the computer in a microwave oven simply runs a single hard-wired program all the time.
