 Observe the following program segment, and choose the appropriate  printf()  statement
from the options to print the value: 

  struct month
 {
  char *month;
 }; 

 int main()
 {
  struct month m={“March”};
  —-
 }
  
printf (“\n Month : %s”, m.month);
Which of the following operators can be applied on structure variables? 
Assignment ( = )
 
A structure variable can be assigned to other using =, but cannot be compared with other using ==
Given the following program, choose the answer:
#include ‹stdio.h›
int main()
{
    struct site
    {
        charname[] = “HKr web site”;
        intno_of_pages = 200;
    };
    struct site *ptr;
    printf(“%d “, ptr->no_of_pages);
    printf(“%s”, ptr->name);

    return 0;
}

Compiler Error
 
When we declare a structure or union, we actually declare a new data type suitable for our purpose. So we cannot initialize values as it is not a variable declaration but a data type declaration.

Bit fields provide the exact amount of bits required for storage.
True
 pnt= (int *)calloc(4,2);
this statement allocates 
  
4 blocks with 2 bytes each
Union have common storage space for all its members. 
True

Predict the output of above program. Assume that the size of an integer is 4 bytes and size of character is 1 byte. Also assume that there is no alignment needed.

The enum keyword is used to define enumerated data type.
True
What will be the value of  m  displayed on execution of the following program? 
  struct bit
 {
  unsigned int m :3;
 };
 int main()
 {
  struct bit b={8};
  
  printf (“\n m = %d”,b.m);
  return 0;
 }

 A memory leak happens when we allocate memory usingmalloc() and then free it using free().
False
The union holds 
  
 one object at a time
The function used to allocate the memory is   
malloc()
The singly linked list is  
  
moves forward only
 Consider the following C declaration
struct{
    short s[5];
    union{
         float y;
         long z;
    }u;
} t;
 
Assume that 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 considerations
  
18 bytes
