nested switch or case statements?

Nested switch or case statements are used when we need to evaluate multiple conditions in a program. In this approach, we have a switch statement inside another switch statement. The outer switch statement evaluates a condition and based on that condition, the inner switch statement is executed to evaluate further conditions.

While nested switch statements can be useful in certain situations, they can also make code harder to read and maintain. It is generally recommended to avoid using too many nested switch or case statements. In most cases, there are other programming constructs like if-else statements or loops that can achieve the same functionality in a more readable and maintainable way.
