Structures, Unions, Enums

What will be output for the following code?

Consider the following C declaration

struct (
short s[5];
union {
float y;
long z;
}u;
}t;

Assume that the objects of the type short, float and long occupy 2 bytes, 4 bytes and 8 bytes, respectively. The memory requirement for variable t, ignoring alignment consideration, is

Which of the following cannot be a structure member?

Size of a union is determined by size of the.

The correct syntax to access the member of the ith structure in the array of structures is?

Assuming: 
struct temp
{
  int b;
}s[50];

Pick the best statement for the below program snippet:

struct {int a[2];} arr[] = {1,2};

What is the output of this program?

#include 
int main()
{
    enum days {MON=-1, TUE, WED=4, THU, FRI, SAT};
    printf("%d, %d, %d, %d, %d, %d", MON, TUE, WED, THU, FRI, SAT);
    return 0;
}

Predict the output of following C program

#include
struct Point
{
  int x, y, z;
};
 
int main()
{
  struct Point p1 = {.y = 0, .z = 1, .x = 2};
  printf("%d %d %d", p1.x, p1.y, p1.z);
  return 0;
}

What will be the output of the following C code?

#include
enum sanfoundry
{
    a,b,c=5
};
int main()
{
    enum sanfoundry s;
    b=10;
    printf("%d",b);
}

What will be the output of the following C code?

#include
enum sanfoundry
{
    a=1,b,c,d,e
};
int main()
{
    printf("%d",b*c+e-d);
}
