31. Find the output of the following program:
void main()
{
struct xx
{
int x=3;
char name[]="hello";
};
struct xx *s;
printf("%d", s->x);
printf("%s", s->name);
}
void main()
{
struct xx
{
int x=3;
char name[]="hello";
};
struct xx *s;
printf("%d", s->x);
printf("%s", s->name);
}32. Consider the following code.
struct account{
int acno;
}svar, *pv = &svar;
then the acno can be accessed by
struct account{
int acno;
}svar, *pv = &svar;then the acno can be accessed by
33. Consider the following declarations:
union id
{
char color;
int size;
};
struct{
char country;
int date;
union id id;
}flag;
To assign a color to a flag, the correct statement would be
union id
{
char color;
int size;
};
struct{
char country;
int date;
union id id;
}flag;To assign a color to a flag, the correct statement would be
34. For the following structure declaration, find the correct statement.
struct person{
char name[20];
int age;
struct person lady;
};
struct person{
char name[20];
int age;
struct person lady;
};35. The restriction with union is
36. How many union members can be initialized?
37. What will be the output of the following C code?
#include <stdio.h>
int main()
{
typedef struct p *q;
struct p
{
int x;
char y;
q ptr;
};
struct p p = {1, 2, &p};
printf("%d\n", p.ptr->x);
return 0;
}
#include <stdio.h>
int main()
{
typedef struct p *q;
struct p
{
int x;
char y;
q ptr;
};
struct p p = {1, 2, &p};
printf("%d\n", p.ptr->x);
return 0;
}38. Can the following C code be compiled successfully?
#include <stdio.h>
struct p
{
int k;
char c;
float f;
};
int main()
{
struct p x = {.c = 97, .f = 3, .k = 1};
printf("%f\n", x.f);
}
#include <stdio.h>
struct p
{
int k;
char c;
float f;
};
int main()
{
struct p x = {.c = 97, .f = 3, .k = 1};
printf("%f\n", x.f);
}39. What will be the output of the following C code?
#include <stdio.h>
int *(*(x()))[2];
typedef int **(*ptrfoo)())[2];
int main()
{
ptrfoo ptr1;
ptr1 = x;
ptr1();
return 0;
}
int *(*(x()))[2]
{
int (*ary)[2] = malloc(sizeof * ary);
return &ary;
}
#include <stdio.h>
int *(*(x()))[2];
typedef int **(*ptrfoo)())[2];
int main()
{
ptrfoo ptr1;
ptr1 = x;
ptr1();
return 0;
}
int *(*(x()))[2]
{
int (*ary)[2] = malloc(sizeof * ary);
return &ary;
