Understand the Problem

The questions are asking about the syntax of the switch statement in programming and what happens when none of the case conditions match. The first question tests knowledge of programming syntax, while the second assesses understanding of control flow in switch statements.

Answer

Correct syntax: 'switch (expression) { case value: break; }'. Default code block executes if no match.

The correct syntax for the switch statement is 'switch (expression) { case value: break; }'. If none of the cases match, the 'default' code block will be executed.

Answer for screen readers

The correct syntax for the switch statement is 'switch (expression) { case value: break; }'. If none of the cases match, the 'default' code block will be executed.

More Information

Switch statements simplify decision-making by allowing execution of specific code blocks based on the evaluated expression. The 'default' option is critical when no specific case is matched.

Tips

A common mistake is using incorrect syntax, such as missing colons or 'break' statements. Always include 'break' to prevent unintended fall-through.
