What is programming logic

Programming Logic is a way to organize your thoughts while following a specific logic, which can be applied by a computer program¹.

Programming logic is a tool used to ease the process of creation of a computer program by a person. This is important because a machine can not understand the human language, as there are several languages, writing styles and even vocabulary. With this in mind, a computer can only understand its own language.

However, a computer’s language is extremely extensive and difficult, as it is based on codes that are read by the processor. This “tongue” also needs to contain defined and clear instructions, which follow a specific order.

Considering this, another ways to “communicate” and command what must be done by a computer program were created. For this, we use programming logic that will create a proper order to write and interpret a code, which will be developed with algorithms and programming languages.


What are algorithms?


Algorithms² are tools used in programming logic, which try to create a logic sequence of steps to reach a specific goal.

They are like a “cake recipe”, in which we define the steps that will be followed to reach the objective.

This way, algorithms are representations of what must be done to solve the problem the program is working on. Moreover, they do not necessarily need to be written in a code, and they can be created in the human language. You can see a graphic example of an algorithm bellow.

Furthermore, algorithms can only be understood by a machine if they are written in their language. For this, it is necessary to use a “translator” between the human and computer tongues. This translation is done by the programming language.


What is a programming language?


A programming language³ is the language used to write the computer program. This means that both the programmer and the computer will be able to understand it. The language is a “translator” for the machine.

In order to write a code, it is necessary to apply the programming logic. We create a clear and defined order of events, which will be used to implement the code.

There are several programming languages, such as JavaScript, Python, Ruby, C++, C#, and others.

These programming languages can be learned by anyone who is interested. It can be in live or online courses and tutorials. Every one of them has its own characteristics, and some work better for specifics situations. However, the language used is mostly a choice made by the programmer.

With this in mind, programming logic is a necessary tool to reach the goal of creating a program. Without it, it is impossible to create a line of thought to be followed by the computer.

You can learn programming logic on tutorials, online and live courses or posts on many websites. This theme is also part of many computation colleges’ curriculum.

If you choose to begin a course, they can be found in many prices, in knowledge trails about programming and even for free. A good Google search will show you many models and school platforms that can be helpful with this choice.
