Coding is a valuable skill that is useful in different fields. The scope of programming is just growing day by day. It is already very important for students, college graduates, researchers, professionals, scientists, businesses, and so many other institutions. These days coding isn’t just for professional programmers. It is for people for all the different fields who take benefit of computer. So programming is a very important skill and it is better to learn it. Everyone can’t take a dedicated class in school, so we have selected some of the best websites to learn coding for free at your own time. You can learn by exploring and with help of experts to become a better coder.

What is Programming?

Computer programming is the process of providing a set of instructions to a computer so that it can perform a specific task. There are many things one user might need to do with a computer, and the program helps to achieve it. For example, it might be a webpage that provides information about a business. It can also be a mobile or Android application that helps to share files. Actually, there are many complex and big programs out there. All these applications have a large set of instructions or codes. These codes have a certain logic and meaning. The program codes help to execute steps according to a set process and algorithm.

Usually, there are a few important steps in programming. This includes understanding the problem, finding solutions, planning, creating algorithms, coding, debugging, and execution. The first steps are natural because we need to first find ways to solve a specific problem. Then only we can write an algorithm or steps to solve that on a computer. Finally, the core part or coding part comes. After writing many lines of code, there can be mistakes in logic, compilation, arithmetic, and syntax. So we might need to go through codes again to check and remove bugs. It is also called debugging and requires good knowledge of the programming language.

Programming Languages and Their Applications

There are so many programming languages available and everyone is different. The languages are classified into different types according to their features, properties, and application. So we must first know what to learn because that is very important. In order to know what to learn, one must know what is the goal and what is way to reach that.

For example, if you need to create a simple fast static website, then you can learn HTML and CSS. If you need a powerful and flexible website then you might need to learn PHP and Javascript. Another example is that if you are a civil engineer and you need to do the calculation of forces of truss elements without any FEM software, then you can learn MATLAB. Suppose you are a mechanical engineer and you need to make subroutines in Abaqus for FEA, then you might need to learn Python. Therefore first find out what you want to achieve.

Every programming language has its own syntax and ways of compiling. However, most of the time, their logic and working principles are the same. If you know how to code in one software and you understand algorithms, then you can get an edge while learning another language. So it is also very important to have a good idea of programming from the school level.

For example, I learned HTML at first, and then I learned QBASIC in school. The concepts of QBASIC helped me to learn C and C++ in my bachelor’s degree. Those concepts again helped me learn MATLAB in my master’s degree. So it is always useful to learn some type of language to improve skills.
