What are Boolean Values?
To begin, it’s essential to understand what exactly boolean values are. In the context of programming , a boolean value is a data type that can have one of two values: true (usually represented by “true”) or false (represented by “false”). At first glance, it might seem like a simple concept, but behind that apparent simplicity lies immense power that drives decision-making in the most complex programs and systems.
Boolean values are inspired by Boolean logic, developed by mathematician and philosopher George Boole in the 19th century. Boole proposed an algebraic system that allowed logical reasoning to be represented by operations with two values: true and false . This binary logic paved the way for the creation of logic gates, digital circuits, and ultimately the foundations of modern computing.
The Logic behind Boolean Values.
The essence of boolean values lies in their ability to express logical propositions and, consequently, allow programs to make decisions based on their veracity. Through three fundamental operators: AND, OR, and NOT, these values can be combined and manipulated to create more complex and sophisticated conditions. Let's see a brief description of each of them:
a) AND: This operator requires that both linked propositions be true for the result to be true. Otherwise, if one or both are false, the result will be false.
b) OR: Here, the result will be true if at least one of the propositions is true. It will only be false if both propositions turn out to be false.
c) NOT: It is a unary operator, which means that it only needs one proposition to work. Its purpose is to invert the original boolean value; if the proposition was true, the result will be false and vice versa.
