What are some disadvantages of a case statement versus repeated elsif
statements?

When comparing the disadvantages of a case (or switch) statement versus repeated elsif (else if) statements, several points can be considered:

1. Limited Data Types: Case statements typically only handle expressions of integer or character data types. This means you cannot use them with floating-point numbers or strings in some languages, which restricts their use to a narrower range of scenarios[4][6].

2. No Support for Complex Conditions: Case statements generally do not support logical expressions or range checking. They are designed to match a single value or expression against a set of constants. In contrast, elsif statements can evaluate complex conditions involving multiple variables and logical operators, allowing for more nuanced decision-making[2][3].

3. Fall-Through Behavior: One of the most notable features of case statements is their fall-through behavior, where if a break statement is not explicitly used, the execution will continue to the subsequent case. This can lead to bugs and unintended behavior if not managed carefully. While this behavior can be useful in certain scenarios, it often requires additional attention to ensure that break statements are correctly placed to prevent fall-through[2][5].

4. Verbosity for Simple Conditions: If the conditions being evaluated are very simple, using a case statement can sometimes be more verbose than necessary, especially if there are only a few conditions to check. In such cases, elsif statements might be more straightforward and easier to read[5].

5. Error Handling: In some languages, if there are no matches within a case statement and there is no default or else clause, it can result in an error and halt execution. This is not the case with elsif statements, which will simply continue execution if no conditions are met[5].

6. Limited to Constants: Case statements typically require that the case labels be constants. This means you cannot use variables or expressions that evaluate at runtime as case labels, which can limit their flexibility compared to `elsif...
