Declare an array of N pointers to functions returning pointers to functions returning pointers to characters?

main() { struct student { char name[30]; struct date dob; }stud; struct date { int day,month,year; }; scanf("%s%d%d%d", stud.rollno, &student.dob.day, &student.dob.month, &student.dob.year); }

main() { struct date; struct student { char name[30]; struct date dob; }stud; struct date { int day,month,year; }; scanf("%s%d%d%d", stud.rollno, &student.dob.day, &student.dob.month, &student.dob.year); }

There were 10 records stored in “somefile.dat” but the following program printed 11 names. What went wrong? void main() { struct student { char name[30], rollno[6]; }stud; FILE *fp = fopen(“somefile.dat”,”r”); while(!feof(fp)) { fread(&stud, sizeof(stud), 1 , fp); puts(stud.name); } }

Is there any difference between the two declarations, 1. int foo(int *arr[]) and 2. int foo(int *arr[2])

What is the subtle error in the following code segment? void fun(int n, int arr[]) { int *p=0; int i=0; while(i++ 1 5275

What is wrong with the following code? int *foo() { int *s = malloc(sizeof(int)100); assert(s != NULL); return s; }

What is the hidden bug with the following statement? assert(val++ != 0);

void main() { int *i = 0x400; // i points to the address 400 *i = 0; // set the value of memory location pointed by i; }

#define assert(cond) if(!(cond)) \ (fprintf(stderr, "assertion failed: %s, file %s, line %d \n",#cond,\ __FILE__,__LINE__), abort()) void main() { int i = 10; if(i==0) assert(i < 100); else printf("This statement becomes else for if in assert macro"); }

Is the following code legal? struct a { int x; struct a b; }

Is the following code legal? struct a { int x; struct a *b; }

Is the following code legal? typedef struct a { int x; aType *b; }aType

Is the following code legal? typedef struct a aType; struct a { int x; aType *b; };

Is the following code legal? void main() { typedef struct a aType; aType someVariable; struct a { int x; aType *b; }; }
