Consider the following program and what will be content of t? #include int main() { FILE *fp; int t; fp = fopen("DUMMY.C", "w"); t = fileno(fp); printf("%d\n", t); return 0; }

Q: Consider the following program and what will be content of t? #include int main() { FILE *fp; int t; fp = fopen("DUMMY.C", "w"); t = fileno(fp); printf("%d\n", t); return 0; }

fp = fopen("DUMMY.C", "w"); A file DUMMY.C is opened in write mode and returns the file pointer to fp t = fileno(fp); returns the handle for the fp stream and it stored in the variable t printf("%d\n", t); It prints the handle number.

size of "DUMMY.C" file
The handle associated with "DUMMY.C" file
Garbage value
Error in fileno()

Correct Answer: The handle associated with "DUMMY.C" file

Explanation:

fp = fopen("DUMMY.C", "w"); A file DUMMY.C is opened in write mode and returns the file pointer to fp

t = fileno(fp); returns the handle for the fp stream and it stored in the variable t

printf("%d\n", t); It prints the handle number.
