Pseudocode Representation of Dual Alternative Decision Structure

In pseudocode, a dual alternative decision structure is represented using an IF-THEN-ELSE statement. Here's a generic example: IF [condition] THEN [block_of_code_if_condition_is_true] ELSE [block_of_code_if_condition_is_false] ENDIF In this structure, the following elements are present: 1. "IF": The keyword representing the beginning of the decision structure. 2. "[condition]": The condition to evaluate. It can be any logical expression that returns a boolean value (True or False). 3. "THEN": The keyword that indicates the start of the code block to be executed if the condition is true. 4. "[block_of_code_if_condition_is_true]": The code to be executed if the condition mentioned is true. 5. "ELSE": The keyword that indicates the beginning of the alternative code block to be executed if the condition is false. 6. "[block_of_code_if_condition_is_false]": The code to be executed if the condition mentioned is false. 7. "ENDIF": The keyword that denotes the end of the decision structure.
