Write a c program to know the last date of modification of any file

#include "time.h"
#include "sys\stat.h"
#include "stdio.h"
int main(){
    struct stat status;
    FILE *fp;
    printf("Last date of modification : %s",ctime(&status.st_ctime));
    return 0;

Function int fstat(char *, struct stat *) store the  information of open file in form of  structure struct stat

Structure struct stat has been defined in sys\stat.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;

(e)st_dev: It describe file has stored in which drive of your computer.

(f)st_mode:  It describes various modes of file like file is read only, write only, folder, character file etc.

(g)st_size: It tells the size of file in byte.

(h)st_ctime:It tells last data of modification of the file in date format.

Function ctime convert date type in string format 

2.  Write a c program to delete a file.
3. Write a c program to copy a file from one location to other location.
6. Write a c program which writes string in the file.
