Computer Programming for Beginners – Programming Foundations  #01

Let’s learn all about computer programming for beginners – Study the basic concepts and elements of programming on any platform using any language. Explore the different uses of different languages and learn how to decide on the right language for a given task. . Work with common processes such as loops, variables, conditions and memory. Familiarize yourself with the flow of a program and its structure. while exploring the dynamics of the program behind the scenes.

Computer Programming for Beginners : What is Programming?

So what is computer programming? You could say it is a set or a series of steps and instructions; a way to command the computer to do what you want it to do. The instructions are given in the form of code which is understood by the computer, with the end goal of solving problems or doing specific tasks. Every computer program you interact with operates through carrying out a certain set of instructions, a series of small and different commands that are implemented one by one.

When programming, these instructions are given to the computer in the form of statements. Each statement, just like everyday language includes words, numbers and punctuation to express a single command. Statements used in most programming languages are usually short, but the exact wording and punctuation that must be used depends on what programming language you use. It is important to understand the rules, or syntax of the different languages when programming.

What programming languages do you need to learn?

The programming language you need to use can change depending on what the end purpose of your program will be. There have been countless programming languages since the dawn of computers, but what’s actually considered popular can change from time to time. Here are a handful of languages that are widely used today.

Java
C
C++
C#
Python
Objective-C
JavaScript
Perl
PHP
Visual Basic
Ruby

When studying computer programming for beginners, you’ll see that it gets easier to learn new languages overtime. Though programmers are sure to learn a number of languages over the course of a career, it must be noted that none of these languages are actually  literally understood by the computer. The only language that your CPU could really understand is called ‘machine code’, which gives direct commands to the computer.

The reason we use programming languages instead of plain machine language is because machine code is extremely tedious and pretty much impossible to write. Also different CPUs would require different machine codes to run because machine language works at the level of your CPU. Due to this, programming languages have been invented that can connect the distance between humans and machines.

The  closer a programming language resembles the machine language, the more difficult it is to write, because a thorough and in-depth knowledge of computer hardware is .required at this stage. Low level languages such as the Assembly language are close to machine code.

High-level languages such as Python, JavaScript, Ruby, and C do not require a programmer to be extensively familiar with computer hardware. They are simpler to write and shareable among other computers and platforms.

Other high-level languages include C++, C#, Objective-C, ActionScript, VB and NET. These languages can work at slightly lower speeds than low-level languages because they are not as close to machine code. However, this is not something you need to worry about on today’s computers.

Whatever language your code is written in, your computer must translate it into machine language before it can follow your instructions. Since this is done automatically by the CPU, all you really need to worry about is your source code; the sequence of instructions you will be writing for the computer.
