Differenciate the below codes

Hi,

What's the difference between these two declarations?

struct x1 { ... };
typedef struct { ... } x2;

Thanks,

hey,

The first structure is named by a tag, the second by a typedef name.

In the first code if you want to create a variable(s) of type x1 you should use the following notation

struct x1 a,b,c;

where as in the second example to create a variable(s) of type x2 you can use the shortest notation like the following since it is a typedef

x2 a,b,c
