Which of the following data types can be used in a switch controlling expression? int, char, and enum int

Ah, the switch statement! A programmer's best friend when it comes to handling multiple choices with ease. In languages like C, C++, and Java, you can use integers, characters, and enumerated types (enums) as controlling expressions in a switch statement. This flexibility allows for cleaner and more readable code compared to multiple if-else conditions. However, keep in mind that using floating-point numbers, strings, or complex data types in switch statements is a no-go! They can lead to unpredictable behavior or errors, so it's essential to stick to the primary types mentioned to keep your code both functional and bug-free!
