我正在创建一组枚举值,但我需要每个枚举值为64位宽.如果我没记错的话,枚举通常与int的大小相同; 但是我认为我读过某个地方(至少在GCC中),编译器可以使枚举成为保持其值所需的任何宽度.那么,有可能有一个64位宽的枚举？

这是一个C++面试测试题而不是作业.

#include <iostream>
using namespace std;
enum months_t { january, february, march, april, may, june, july, august, september,    
  october, november, december} y2k;

 int main ()
  {
    cout << "sizeof months_t is  " << sizeof(months_t) << endl;
    cout << "sizeof y2k is  " << sizeof(y2k) << endl;
    enum months_t1 { january, february, march, april, may, june, july, august,    
       september, october, november, december} y2k1;
    cout << "sizeof months_t1 is  " << sizeof(months_t1) << endl;
    cout << "sizeof y2k1 is  " << sizeof(y2k1) …
