当然,类型保存也可以扩展到模板的使用,Clang保留了关于特定模板特殊化(如 std:::vector)在源代码中如何拼写的信息。比如说: $ clang -fsyntax-only t.cpp t.cpp:12:7: error: incompatible type assigning 'vector', expected 'std::string' (aka 'class std::basic_string') str = vec; ^ ~~~ 修复提...
string a="abc"; cout<<3+a; //将一个整数与一个string类型的变量相加,这是+运算不允许的 2.在使用自己定义的类时,尝试使用系统默认的运算符 比如: class Integer{ public: int a; Integer(int aa):a(aa){} }; Integer a(1),b(2); cout<<a+b; //因为系统的+运算没有对自定义的类的运算方...
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int_ error C4772: #import referenced a type from a missing type library; '__missing_type__' used as a placeholder error C4996: 'strcpy': This function or variable may be unsafe. error code 0x80040200...
the duplication across attribute-specifiers are to support cases where macros are used to conditionally add attributes to an attribute-specifier-seq, however it is rare for macros to be used to generate attributes within the same attribute-list. Thus, removing the limitation for that reason is unn...
template <class T> // alternatively, could be 'template <typename T>'; 'typename' is not elaborating a type specifier in this case class container; 初始值设定项列表中数组的类型推断 早期版本的编译器不支持对初始值设定项列表中的数组进行类型推断。 编译器现在支持这种形式的类型推断,因此调用使用初...
