[previous] 1041 [next] [E] Empty aggregate initializers are a language extension.
Language extensions

An empty initialiser "{ }" has been used to initialize a struct or a union. This is a language extension.

Empty "aggregate initializers" are supported by some compilers as a shorthand for "{ 0 }". They are also sometimes interpreted as a placeholder initialiser for empty structs or zero length arrays.

For example: 


/*PRQA S 1314,2017,2213,3132,3211,3408,3603 ++*/

extern int ea [2] = { };           /* Message 1041 */
extern int eb [0] = { };           /* Message 1041 and 1037 */

struct st1
{
    int n;
    struct st2 { } sa;             /* Message 0633 */
};

extern struct st1 xs = {1, { }};   /* Message 1041 */
