有没有办法在 C++ 源代码中用空格编写大量数字以使其更具可读性?
假设我有代码:
vector<int> temp = vector<int>(1 000 000 000);
以上不会编译，因为编译器会抱怨空格.是否可以指示 C++ 在编译时省略这些空格，或者以其他方式使数字更易于阅读?
The above will not compile as the compiler will complain about the spaces. Is it possible to indicate to C++ to ommit those spaces when compiling, or otherwise make the number easier to read?
推荐答案
试试数字分隔符:
int i = 1'000'000'000;
此功能是 自 C++14 引入的.它使用单引号 (') 作为数字分隔符.
This feature is introduced since C++14. It uses single quote (') as digit separator.
另见:
- 为什么没有为 C++14 数字分隔符选择空格字符?
- 泛化 C++2000 的重载(C++ 之父 4 月的笑话)
- Why was the space character not chosen for C++14 digit separators?
- Generalizing Overloading for C++2000 (April's joke by the father of C++ himself)
