How can we access the elements in structure,where structure present in union?

Answer 1

You either have to use an anonymous struct inside a union like so

typedef union {
struct {
int a;
double b;
};
} un;

and access the members of the struct as

int main() {
un x;
x.a = 5;
x.b = 1.5;
}

or create an object of a regular struct right after the struct definition inside the union like this

typedef union {
struct str {
int a;
double b;
} s;
} un;

and access the members of the struct as

int main() {
un x;
x.s.a = 5;
x.s.b = 1.5;
}
