There are courses of programming that start from the lowest levels, so you do not need to have previous knowledge in the matter and others in what you have to have a basic level, you only have to choose the one that best suits your level of knowledge.
For those who start in the world of programming we wanted to give them this small informative theme.
This Pack of free online courses of programming is aimed at all those people, who have previous knowledge in the subject or not, people who want to learn the latest technologies of programming or improve their level of knowledge.
Programming is a creative process that instructs a computer on how to do a task. Hollywood has helped instill an image of programmers as technology experts who can sit in front of a computer and break any password in seconds. The reality is much less interesting.
A programming language is a set of commands, instructions, and other syntax use to create a software program. The languages that programmers use to write code are called "high-level languages ". This code can be compiled into a "low-level language ", which is recognized directly by the computer hardware.
High-level languages are designed to be easy to read and understand. This allows programmers to write the source code naturally, using logical words and symbols. For example, words reserved as function, while, if, and else are used in most major programming languages. Symbols like <, >, = = and! = are common operators. Many high-level languages are similar enough so that programmers can easily understand the source code written in multiple languages.
Examples of high-level languages include C + +, Java, Perl, and PHP. Languages such as C + + and Java are called "compiled languages " because the source code must first be compiled in order to be executed. Languages such as Perl and PHP are called "interpreted languages " because the source code can be executed through an interpreter without being compiled. In general, compiled languages are used to create software applications, while interpreted language is used to run scripts, such as those used to generate content for dynamic Web sites.
Low-level languages include assembly and machine languages. An assembly language contains a list of basic instructions and is much harder to read than a high-level language. In exceptional cases, a programmer may decide to encode a basic program in an assembly language to ensure that it works in the most efficient manner possible. An assembler can be used to translate the assembly code into the machine code. Machine code, or machine language, contains a series of binary codes that are directly understood by a computer's CPU. It goes without saying that the machine language is not designed to be human-readable.
Computer programming is used for a variety of purposes: computer programming helps develop programming languages that are used to transform computing problems into instructions.
C + +
Some programs do not need to be compiled separately. Rather, it is made up of a just-in-time process on the computer for which it is running. These programs are called interpreted programs. Popular computer programming languages interpreted include:
The following are some of the important features of a good programming language:
1. Language should allow the programmer to write simple, clear and concise programs.
2. Language should be simple to use so that a programmer can learn it without any explicit training.
3. Language must be platform-independent. In other words, the program developed using the programming language can be executed in any computer system.
4. The graphical user interface (GUI) of the language must be attractive, friendly and self-explanatory.
5. The function library used in the language must be well documented so that the necessary information about a function can be obtained when developing the application.
6. Several language-compatible programming constructions must match the application area for which you are using.
7. Programs developed in language should make efficient use of memory and other computer resources.
8. Language must provide the tools necessary for the development, testing, debugging and maintenance of a program. All of these tools must be incorporated into a single environment known as the Integrated development environment (IDE), which allows the programmer to easily use them.
9. Language must be consistent in terms of syntax and semantics.
Here are the 10 easiest-to-learn programming languages, and the percentage of developers who designated them as well, based on a series of surveys conducted on different programmers.
1. HTML (13.3%)
HTML was designated as the easiest to learn programming language, and with which programmers are more comfortable, found WP Engine. Created in 1990, this markup language is one of the main tools for creating Web pages and standard applications in any browser.
2. Python (9%)
Python is known for its high readability and simple syntax that is easy to learn, according to the report. "For the new encoders, especially the consistency and simplicity of Python contribute to its ease of use and accessibility," said the report. Initially created in 1989, Python has been in use for almost 25 years since its first release in 1994.
4. PHP (4.9%)
PHP is a general-purpose open-source scripting language that is especially suitable for web development and can be integrated into HTML.
5. Java (4.6%)
Java is a general-purpose programming language that is specifically designed to have as few deployment dependencies as possible. Created in 1991, Java was also ranked as one of the most popular and versatile languages to write.
6. R (4.4%)
R is an open source programming language for computation and statistical graphics supported by the R Foundation for statistical Computing.
7. Shell (4.4%)
A shell script is a computer program designed to be run by the Unix shell. Typically used for file manipulation, program execution, and text printing.
8. Ruby (4.1%)
Ruby is a dynamic, open-source programming language with a focus on simplicity. He also held a prominent place in the list of the most creative programming languages.
9. Erlang (3.8%)
Erlang is a functional, concurrent and general-purpose programming language. It is used to develop concurrent and distributed systems.
10. GO (3.6%)
Go, Google's open-source programming language, is useful for developing Web applications with minimal frames, Web servers, or APIs, the report said. It is also easy to implement a Go application that runs on the Google Cloud Platform. Go was also classified as one of the most intuitive programming languages.
11. C# or C Sharp
A relatively new language, but do not confuse this. Thanks to its resemblance to C / C ++ as the JAVA has acquired an almost explosive popularity among lovers of programming, this supported by the implementation of the MONO project that allows it to run not only on Windows platforms, but also in LINUX, IOS, ANDROID
