Why is logic programming different from procedural programming?

Expert Solution
Step 1

Logic programming is a programming paradigm that is based on formal logic, whereas procedural programming is a programming paradigm that is based on the step-by-step procedures or algorithms that a program should follow to achieve a specific task.

One of the primary differences between the two programming paradigms is that in logic programming, the program is written in terms of logical statements and rules that define relationships between objects and how they interact, rather than explicitly specifying a series of steps to execute.

In logic programming, the programmer specifies what the desired outcome should be, and the logic programming language's interpreter or compiler uses rules of inference and deduction to determine how to achieve that outcome. This approach is often called declarative programming because the programmer declares what they want the program to do, and the language handles the details of how to achieve it.

Procedural programming, on the other hand, focuses on defining a series of steps or procedures that a program should follow to accomplish a task. The programmer specifies the sequence of actions that the program should take to achieve a goal.
