9. statements (conditional statements)
This document discusses different types of flow control statements in C/C++, including sequential statements, conditional statements, and iterative/looping statements. Conditional statements include if, if-else, nested if-else, and if-else ladders. If statements execute code if a condition is true, if-else adds else blocks to execute if false, nested if-else places if-else blocks within each other, and if-else ladders check multiple conditions in sequence. Examples are provided for each type of conditional statement.
