One-way selection

A selection structure where actions are taken based only on a single condition being true.

Two-way selection

A selection structure where different actions are executed based on a condition being either true or false.

Multi-selection

A selection structure that allows the program to choose from multiple actions based on the value of an expression, such as the switch statement.

IF Statement

A statement that executes a block of code if a specified boolean expression evaluates to true.

IF/ELSE Statement

A statement that executes one block of code if a condition is true and another block if the condition is false.

SWITCH Statement

Logical Operators

Operators that combine multiple boolean expressions, evaluating them to true or false.

Assignment Operator

Flowchart

A visual representation used to illustrate the flow of the program, particularly for control structures.

Example of IF statement

If average greater than 60, output 'PASSED'.

Logical Expression
