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; }

Consider the following program and what will be content of t?

#include<stdio.h>

int main()
{
    FILE *fp;
    int t;
    fp = fopen("DUMMY.C", "w");
    t = fileno(fp);
    printf("%d\n", t);
    return 0;
}

[A].	size of "DUMMY.C" file
[B].	The handle associated with "DUMMY.C" file
[C].	Garbage value
[D].	Error in fileno()

Answer: Option B

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.
