If the following structure is written to a file using fwrite(), can fread() read it back successfully? struct emp { char *n; int age; }; struct emp e = { "Sujay",15}; FILE *fp; fwrite (&e, sizeof (e), 1, fp);

Correct Answer: A typedef defines a new name for a type, and in simpler cases like the one shown below you can define a new structure type and a typedef for it at the same time typedef struct { char name[20]; int age; } emp; However, in the structure defined in this question, there is an error because a typedef declaration cannot be used until it is defined In the given code fragment the typedef declaration is not yet defined at he point where the link field is declared

Correct Answer: 1 2

Correct Answer: Use the typecast scr = (char far *) 0xB8000000;

Correct Answer: An error would be reported in the statement k++ since arithmetic on void pointers is not permitted unless the void pointer is appropriately typecasted

Correct Answer: 65486 65486

Correct Answer: DRAVID When a structure is assigned, passed, or returned, the copying is done monolithically This means that the copies of any pointer fields will point to the same place as the original In other words, anything pointed to is not copied Hence, on changing the name through e2n it automatically changed e1n

Correct Answer: struct emp { char n[20]; int age; }; main() { struct emp e1 = {"Dravid", 23}; struct emp e2; scanf ("%s %d",e2n, & e2age); if( structcmp (e1,e2) ==0) printf ("The structures are equal"); else printf ("The structures are unequal"); } structcmp ( struct emp x, struct emp y) { if (strcmp (xn,yn) ==0) if (xage == yage) return (0); return (1); } In short, if you nee to compare two structures, you'll have to write your own function to do so which carries out the comparison field by field

Correct Answer: The last line from the file "trial" would be read twice To avoid this, ues: While ( fgets (str, 80, fp) ! = NULL) puts (str);

Correct Answer: C: \SAMPLEEXE

Correct Answer: 6

Explanation:

When atoi() tries to convert argv[0] to a number it cannot do so (argv[0] being a file name) and hence returns a zero.
