Intro to Conditionals

Conditionals are a fundamental concept in programming that allow a program to make decisions based on conditions. Programs evaluate Boolean expressions, which return either true or false, and then execute different actions depending on the result. This allows programs to respond dynamically to different inputs or situations.
