Consider the following C declaration

struct{short s[5];union{

float y;long z;}u;}t;

Assume size of short,float,long as 2,4,8 bytes respectively. predict size of t ignoring alignment considerations

struct node{

   int i;float j;};

struct node *s[10];

The above C declaration define ‘s’ to be

• an array ,each element of which is a pointer to a structure of type node

• structure of 2 fields,each field being a pointer to an array of 10 elements

• A structure of 3 fields,an integer,a float,and an array of 10 elements

• an array ,each element of which is a structure of type node

• No compile time error,generates an array of structure of size 3

• No compile time error,generates an array of structure of size 9

• Compile time error, illegal declaration of a multidimensional array

• Compile time error, illegal assignment to members of structure

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

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

• s.b.[i]

• s[i].b

• s.b[i]

• s.[i].b
