C Programming - Typedef - Discussion

In this structure variables act as int (all variables). So output is 1.

#include<stdio.h>
typedef struct error {int warning, err, exception;} ERROR;

/* typedef is used to rename. Here the name of the struct is changed from error to ERROR.............. */
int main()
{
ERROR e;
/* e is the object of ERROR structure ... */
e.err=1;
/* the value of err has been initialized with the help of object to the value 1 */

printf("%d\n", e.err);
/* 1 is the output............ */

return 0;
}

@ALL.

As per my knowledge;

#include<stdio.h>

typedef struct error {int warning, err, exception;} ERROR;
int main()
{
ERROR e; /*typedef is used to rename. So (ERROR) as changed to (struct error) */
/* the above line code (ERROR e;) as changed to (struct error e;)*/

e.err=1;
printf("%d\n", e.err);
return 0;
}

Can we write the semicolon inside a closing curly braces? Please tell me.
