What Is Unary Operator?

So, a #unaryoperator is just a fancier way of saying a single operator that executes an action on one #operand. This is because a #unaryoperator only works with one #operand. Imagine it as a #robot with only one arm that can perform a #specific task using the hand it has been given. It is analogous to a lever with only one side that can be pushed or pulled. One example of a unary operator that can negate a numerical value is the #negation operator also referred to as the minus sign. If you start with the number 5 and then place the negation operator in front of it, the result is the negative number -5. The robot's arm is switching the value of the number from positive to negative or vice versa. One more type of unary operator is the increment operator (++), which takes a numerical value and adds one. If you already have the number 5 and apply the increment operator, the result is the number 6 instead. The robot's single arm was adding one to the total. The #decrement operator (--), which reduces a numerical value by 1, is the following operator. If you start with the number 5 and then apply the decrement operator, the result is the number 4 instead. It's almost as if the robot's single arm deducted one from the total. You can also get the memory address of a variable by using the #address-of operator (&), which does the same thing. The #dereference operator represents the symbol * and returns the value currently stored at a specific memory address. Last but not least, there is an operator known as the logical not (!) that flips the value of a boolean. If you start with the boolean value true and then apply the logical-not operator to it, the result is that the value is changed to false. That wraps up what you need to know about unary operators! In the world of programming, despite their apparent simplicity, these tools are among the most powerful there. They may only have one arm, but they can still complete the task at hand, just like a robot with only one arm. #ComputerScience #Programming #Coding #Programming
