Question 2: Struct and Union

What is the size of the following data structures in bytes.

a) Size of point3D (2 pts)

struct point3D {

signed short x;

unsigned int y;

char *z;

};

b) Size of val (2 pts)

union val {

long long llval;

char str;

short ival[2];

float fval;

double dval;

};

c) Size of compound (2 pts)

struct compound {

char mystring;

long *y;

union {

char *c;

short i;

char f;

} u;

};

d) Size of more_compound (2 pts)

struct more_compound {

char name;

int *age;

short pay;

long height;

union {

char short_id;

short normal_id;

char my_id;

} id;

union {

char *text_data;

int *numeric_data;

long *l_numeric_data;

} data;

};
