What is one key purpose of using the case structure in pseudocode?

It only serves to identify a boolean expression.
It simplifies the syntax of complex conditionals. (correct)
It can replace all if statements.
It allows for infinite cases without conditions.

In a switch statement, what does the 'break' command accomplish?

It terminates the entire program.
It exits the switch and does not execute further statements. (correct)
It allows the execution to continue into the next case.
It restarts the switch statement from the beginning.

How does the structure of CASE OF differ from an IF statement in pseudocode?

CASE OF allows for multiple conditions to be handled separately. (correct)
IF statements allow for more complex nested conditions.
IF statements cannot incorporate boolean expressions.
CASE OF must always include a default case.

IF statement syntax

The basic syntax for an IF statement in programming involves checking a boolean expression and executing code if the expression is true.

CASE structure

The CASE structure is a way of organizing conditional logic, similar to nested IF statements, making code more readable and easier to understand.

Switch statement

A switch statement is a concise way of expressing multiple conditional branches based on a variable's value. It often replaces nested IF-ELSE structures for cleaner code.

Break statement

The break statement is used inside a switch statement to exit the current block of code after a matching case is found. It prevents unintended execution of subsequent cases.
