Answer Posted / vignesh1988i

here the error is the variable declaration of struct xx is not permitted inside struct yy. since this is nested structures ,so according to the braces for each structures the variables for that particular structure should be assigned (OR)
if this is written as code given below this will be correct.
THIS IS THE CORRECT CODE WHICH WILL GIVE NO ERROR.
struct xx
{
int a;
}
struct yy
{
char c;
struct xx *p;
}
struct yy *q

THE SAME CODE GIVEN IN THE QUESTION CAN BE CORRECTED AS :

struct xx
{
int a;
struct yy
{
char c;
}*q // for struct yy
}*p // for struct xx
