Compiler Warning (level 1, Error) C4430

  • Artikel

missing type specifier - int assumed. Note: C++ does not support default-int

This error might be generated due to compiler conformance work done for Visual Studio 2005: all declarations must explicitly specify the type; int is no longer assumed.

C4430 is always issued as an error. You can turn off this warning with the #pragma warning or /wd. For more information, see warning or /w, /W0, /W1, /W2, /W3, /W4, /w1, /w2, /w3, /w4, /Wall, /wd, /we, /wo, /Wv, /WX (Warning Level).

Example

The following sample generates C4430:

// compile with: /c
struct CMyClass {
   CUndeclared m_myClass;  // C4430
   int m_myClass;
};

typedef struct {
   someFunction();   // C4430
   unsigned x;
   unsigned y;
} POINT;

The following addresses C4430:

// compile with: /c

#include "CUndeclared.h" // for `CUndeclared`

struct CMyClass {
   CUndeclared m_myClass;
   int m_myClass;
};

typedef struct {
   int someFunction();
   unsigned x;
   unsigned y;
} POINT;
