二维数组赋值

列的大小必须指定。

正确 char eth[][8]={"p32p1","p33p1","p34p1","p35p1"};

报错 char eth[4][]={"p32p1","p33p1","p34p1","p35p1"};

     char eth[][]={"p32p1","p33p1","p34p1","p35p1"};

ts.c: In function ‘IP’:
ts.c:65:7: error: array type has incomplete element type
char eth[4][]={"p32p1","p33p1","p34p1","p35p1"};
