Assigning Integers to an Enum Type

In C, it is valid to assign integers to an enumerated type. For example:

 
/*** valid in C but not C++ ***/

enum Status {good, bad};
void func()
{
  Status stat = 1;  /* integer assignment */
}

In C++, however, enums are strongly typed. You can only assign enumerators of the same enum type to an enum variable. Explicit type casting is required otherwise. For example:

 
//C++
enum Status {good, bad};
void func()
{
  Status stat = static_cast<Status> (1);  // stat = bad
}
