Categorical logic deals with the relationships between categories or classes of objects, focusing on the inclusion and exclusion of these categories (e.g., all, some, none). It uses terms like "All A are B" to establish connections between different categories. In contrast, propositional logic focuses on the truth values of entire statements or propositions, using logical connectives like "and," "or," and "not" to form complex expressions. Thus, while categorical logic emphasizes relationships between groups, propositional logic centers on the truth conditions of statements.

Flowchart it is diagrammatic Program it is coding. A flowchart is drawn out on paper, and shows the logic of an if/then/else statement. The programming actually is the if/then/else, not just the logic.
Truth tables are essential in propositional logic as they provide a systematic way to evaluate the truth values of complex logical expressions based on the truth values of their individual components. By listing all possible combinations of truth values for the propositions involved, truth tables help in determining the validity of logical arguments and the equivalence of different expressions. Additionally, they serve as a foundational tool for teaching the principles of logic, aiding in the visualization of logical operations such as conjunction, disjunction, and negation. Overall, truth tables enhance understanding and facilitate problem-solving in logical reasoning.
Its a algorithm. DPLL/Davis-Putnam-Logemann-Loveland algorithm is a complete, backtracking-based algorithm for deciding the satisfiability of propositional logic formulae in conjunctive normal form, i.e. for solving the CNF-SAT problem.

Difference between Propositonal and Predicate logic
in propositional logic a complete sentence can be presented as an atomic proposition. and complex sentences can be created using AND, OR, and other operators.....these propositions has only true of false values and we can use truth tables to define them... like book is on the table....this is a single proposition... in predicate logic there are objects, properties, functions (relations) are involved.
To ensure the soundness and completeness of propositional logic, we must verify that all logical arguments are valid and that all valid conclusions can be reached using the rules of propositional logic. Soundness means that the premises of an argument logically lead to the conclusion, while completeness means that all valid conclusions can be derived from the premises. This can be achieved through rigorous proof methods and adherence to the rules of propositional logic.
categorical logic
Categorical logic originated with Bill Lawvere's Functorial Semantics of Algebraic Theories (1963), and Elementary Theory of the Category of Sets (1964)
Have a look at this website.. It answers your question very nicely. http://www.rbjones.com/rbjpub/logic/log003.htm
Proposition in logic refers to the statements that are either true or false, but not both. Such kind of statements or sentences are usually called propositions.
Krister Segerberg has written: 'Results in non-classical propositional logic' -- subject(s): Addresses, essays, lectures, Logic, Modality (Logic)
Examples of formal logic include propositional logic, predicate logic, modal logic, and temporal logic. These systems use symbols and rules to represent and manipulate logical relationships between statements. Formal logic is used in mathematics, computer science, philosophy, and other fields to reason rigorously and draw valid conclusions.

Categorical Logic
A statement that is either true or false is known as a propositional statement or a proposition. For example, "The sky is blue" is a propositional statement because it can be evaluated as true or false based on the conditions at a given time. Propositional logic relies on these types of statements to form logical arguments and reasoning.
