Nested If Statements: Nested if statements are if statements that are placed inside other if or else if statements. They allow for more complex decision-making by checking additional conditions within existing conditions.
Boolean Expressions:Boolean expressions represent logical values (true or false) and are used in conditional statements like else if. They involve comparison operators such as equals (==), greater than (>), or less than (<).
Control Flow: Control flow refers to the order in which instructions are executed in a program. Else if statements help control the flow by providing alternative paths based on specific conditions.
