Structures, Unions, Enums

Assume that size of an integer is 32 bit. What is the output of following program?

#include
struct st
{
    int x;
    static int y;
};
 
int main()
{
    printf("%d", sizeof(struct st));
    return 0;
}

Which operator connects the structure name to its member name?

What is the output of this program?

#include 
 struct 
{
 int i;
 float ft;
}decl;
int main(){
    decl.i = 4;
 decl.ft = 7.96623;
 printf("%d %.2f", decl.i, decl.ft);
 return 0;
}

Which of the following accesses a variable in structure *b?

Consider the following declaration :

struct addr {
     char city[10];
     char street[30];
     int pin ;
};

struct {
char name[30];
int gender;
struct addr locate;
} person , *kd = &person ;

Then *(kd -> name +2) can be used instead of

Point out the error( if any) in the following code.

#include
enum sanfoundry
{
    a,b,c
};
enum sanfoundry g;
main()
{
    g++;
    printf("%d",g);
}

User-defined data type can be derived by___________

String handling functions such as strcmp(), strcpy() etc can be used with enumerated types.

Can we have enum containing enum with same contestant?

#include "stdio.h"

enum Yenum{
       C, CPP, Java
};

enum Xenum{
    C, CPP, Java, Yenum
};

int main()
{
  enum Xenum var;
  printf("%d",sizeof(var));
  return 0;
}

What is the output of this program?

#include 
struct result{
  char sub[20];
  int marks;
};
void main()
{
      struct result res[] = { {"Maths",100},
      {"Science",90},
      {"English",85}
      };
    printf("%s ", res[1].sub);
    printf("%d", (*(res+2)).marks);
}
