Answer #include <time.h>
#include <sys\stat.h>
#include <stdio.h>
void main()
{
struct stat status;
FILE *fp;
fp=fopen("test.txt","r");
fstat(fileno(fp),&status);
clrscr();
printf("Size of file : %d",status.st_size);
printf("Drive name : %c",65+status.st_dev);
getch();
}
+ ExplanationNot ModeratedFunction int fstat (char *, struct stat *) store the information of open file in form of structure struct stat Structure struct stat has been defined in sysstat.h as
struct stat {
short st_dev, st_ino;
short st_mode, st_nlink;
int st_uid, st_gid;
short st_rdev;
long st_size, st_atime;
long st_mtime, st_ctime;
};
Here
(a)st_dev: It describe file has stored in which drive of your computer ,it returns a number.
(b)st_mode: It describes various modes of file like file is read only, write only, folder, character file etc.
(c)st_size: It tells the size of file in byte.
(d)st_ctime:It tells last data of modification of the file in date format.Note: 65 is ASCII value of A .So after adding status.st_dev with 65 it will return appropriate drvie name as in your computer.
