【C++标准I/0库】错误：runtime_error was not declared

# 编译出现：runtime_error was not declared

#include <iostream>

错误：

||=== Build: Debug in Demo6 (compiler: GNU GCC Compiler) ===|

G:\C_Code black\day0404\Demo6\main.cpp||In function 'std::istream& get(std::istream&)':|

G:\C_Code black\day0404\Demo6\main.cpp|14|error: 'runtime_error' was not declared in this scope|

||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

解决方法：

加上头文件：#include <stdexcept>

拓展：若出现编译错误error: 'numeric_limits' is not a member of 'std'

加上头文件：#include <limits>
