Can a switch statement evaluate enum?

Yes , You can use Enum in Switch case statement in Java like int primitive.

The solution is very simple. You need an enumeration and a std::map , and that’s it. The enumeration defines the numeric values use in the switch statement. The std::map contains the link between the valid string values you want to compare some runtime data against, and the numeric enum values you can make a switchon.

switch is only for integral types , if you want to branch depending on a string you need to use if/else .

Use Custom Defined Function to Convert an Enum to a String in C++ Alternatively, we can define our own function, which takes an integer as a parameter and returns a string value. The string variable is initialized with a const char* value from enum_str array inside the function.

Here we will see how to map some enum type data to a string in C++. There is no such direct function to do so. But we can create our own function to convert enum to string . We shall create a function that takes an enum value as the argument, and we manually return the enum names as a string from that function.

In C++, enums are permitted to have values other than the explicit enumerators. … After execution falls through the switch statement, it reaches the end of the function without returning a value, which is undefined behavior for a function with a non-void return type.
