catch (exception e) { cout << e.what() << endl; } system("pause"); return 0; } 输出结果: (2)数值转字符串 转十进制可以用to_string,但是低版本的编译器可能不支持 转多进制可以用_itoa_s,但似乎没有安全机制,导致无法捕获异常 char cstr[20]; _itoa_s(100,cstr,2); cout << cstr << ...
2)所有标准异常的根在于exception基类<exception>。 主要包含what方法返回错误描述。 exception基类不包含以string为参数的构造函数,所以,不能throw exception(“Error”);一般不从这个根类直接继承,从下面的派生类继承。 error: no matching function for call to ‘std::exception::exception(const char [4])’ 改...

② logic_error类及其子类、runtime_error类及其子类,它们的构造函数是接受一个string类型的形式参数,用于异常信息的描述; ③ 所有的异常类都有一个what()方法,返回const char* 类型(C风格字符串)的值,描述异常信息。 标准异常类的具体描述: 原文:https://blog.csdn.net/songzi1111/article/details/9299587 ...
