我想我没有得到什么。
该类cpp_int是否boost::multiprecision应该保存与想要的一样大的整数？假设我想存储以下大得离谱的整数。我该怎么做呢？
#include <boost/multiprecision/cpp_int.hpp>
using namespace boost::multiprecision;
cpp_int n = 999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999;
以下代码返回
error: integer literal is too large to be represented in any integer type
正如文档中详细说明的，您需要使用字符串来构造：
cpp_int n{"999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999"};
