C++笔记之enum class和emun的区别

code review!

代码,使用 enum class 的示例：

#include <iostream>enum class Month { January, February, March, April, May, June, July, August, September, October, November, December };int main() {Month currentMonth = Month::August;if (currentMonth == Month::August) {std::cout << "It's August!" << std::endl;}// Uncommenting the following line will result in a compilation error// if (currentMonth == December) {//     std::cout << "It's December!" << std::endl;// }return 0;
}

代码,使用普通的 enum 的示例：

#include <iostream>enum Month { January, February, March, April, May, June, July, August, September, October, November, December };int main() {Month currentMonth = August;if (currentMonth == August) {std::cout << "It's August!" << std::endl;}// The following line compiles successfully, but it's not type-safeif (currentMonth == December) {std::cout << "It's December!" << std::endl;}return 0;
}
