Overview of If-Else Branches

• If-Else statements enable conditional branching in programming, altering execution flow.

Flowchart Explanation

• Flowcharts visually depict programming logic, exemplified by a Hotel Rate Discount Program where

  • Initial rate: $155; if user age > 65, rate decreases to $135.

Calculating Absolute Values

• Absolute value reflects distance from zero:

  • Positive stays the same (|5| = 5); negative becomes positive (|-10| = 10).

• Steps: Input number, check if < 0, convert if true, output.

If-Else Structure

• Determines outcomes based on conditions, e.g., insurance payments based on age.

Python Implementation

• Translates flowcharts: if condition true, execute; else, execute alternative.

• Uses == for equality checks.

Multi Branch & Logical Operators

• elif handles multiple conditions; use logical operators (AND, OR, NOT) for combining conditions.

Summary of Boolean Logic

• Boolean variables are true/false; evaluated conditions yield boolean results.
