How to cast int to enum in C++?

Question

How do I cast an int to an enum in C++?

For example:

enum Test
{
    A, B
};

int a = 1;

How do I convert a to type

Answer 1

Test castEnum = static_cast(a-1); will cast a to A. If you don't want to substruct 1, you can redefine the enum:

enum Test
{
    A:1, B
};

In this case Test castEnum = static_cast(a); could be used to cast a to A.
