Conditional statements and loops #2

Lesson 2: Conditional Expressions and Loops

2.1 Conditional Statements (if, else, elseif)

Conditional expressions allow you to run different blocks of code depending on whether a certain condition is true or false. Here is an example:

This program checks whether the variable $not is 50 or greater and prints the message "You passed!" or "You failed." depending on the case.

2.2 Loops (for, while, do-while)

Loops are used to repeat a certain block of code as long as a certain condition is met.
