Pseudocode – Input, Output, and Operators

Input Command

INPUT <identifier>

- The identifier must be a variable.

- It may represent an individual element of a data structure (e.g., array or custom type).

Output Command

OUTPUT <value(s)>

- One or more values can be output in a single command.

- Multiple values are separated by commas.

Addition +

Subtraction -

Multiplication *

Division /

Notes:

- Division results should be of data type REAL, even if operands are integers.

- Use MOD and DIV for integer division, but explain their use explicitly.

- Multiplication and division have higher precedence than addition and subtraction.

- Use parentheses to make complex expressions clear.

Relational (Comparison) Operators

Greater than >

Less than <

Greater than or equal to >=

Less than or equal to <=

Equal to =

Not equal to <>

- The result of these operations is always BOOLEAN (TRUE or FALSE).

Logical Operators

AND: True if both conditions are true

OR: True if at least one condition is true

NOT: Reverses the logical value

- Operands and results are always of data type BOOLEAN.

String Operations

- Operations like concatenation, searching, and splitting vary between systems.

- Always explain clearly how they are used in pseudocode.

- When formatting numbers as strings for output, describe the function explicitly.

Random Number Functions

RANDOMBETWEEN(min, max): Generates a random integer between min and max.

RND(): Generates a random real number between 0 and 1.
