[previous] 2051 [next] The 'int' type specifier has been omitted from an object declaration.
Declarations and Definitions

The type of an object has not been explicitly defined and is therefore implicitly defined as int. This is permitted in ISO:C90 but is not allowed in ISO:C99.

For example: 


/*PRQA S 506,2017,3210,3227,3408,3447,3602 ++*/

extern foo1(void);                      /* Message 2050 */

extern const va;                        /* Message 2051 */

extern int foo2(const * p)
{                                       /* Message 2051 */
    return *p;
}

extern foo3(void)
{                                       /* Message 2050 */
    const x = 10;                       /* Message 2051 */
    return x;
}
