An "if" or an "only-if" statement. It is conditional because its truth value is determined by the truth value of two other statments. Logical Reasoning

a set of commands that executes if a specified condition is true

a statement expressing the relation of material implication

a statement that we're all familiar with

an "if p, then q" compound statement (ex. If I throw this ball into the air, it will come down); p is called the antecedent, and q is the consequent. A conditional asserts that if its antecedent is true, its consequent is also true; any conditional with a true antecedent and a false consequent must be false. For any other combination of true and false antecedents and consequents, the conditional statement is true.

A logical statement involving a comparison, which yields a Boolean (True or False) value.

A statement that can be expressed as an if-then statement. For example, "If a polygon is a hexagon, then it has exactly six sides" (Lesson 2.3). The first part of the conditional is called the antecedent. The second part is called the consequent (Lesson 14.8).

In computer science, conditional statements are a vital part of a programming language. These statements are requests to the computer to make an execution choice based on a given condition.
