Question

*** please the answer in C language , and please type it NOT hand writing .

Answer 1

c program that prints properties and contents of a directory:

#include <stdio.h>
#include <dirent.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
void printFileProperties(struct stat stats);
int main(void)
{
   struct dirent *de;
   DIR *dr = opendir(".");
struct stat stats;
   if (dr == NULL) {
       printf("Could not open current directory" );
       return 0;
   }
   while ((de = readdir(dr)) != NULL){
           printf("Name: %s\n", de->d_name);
if (stat(de->d_name, &stats) == 0){
printFileProperties(stats);
}
   }
   closedir(dr);
   return 0;
}

/**
* Function to print file properties.
*/
void printFileProperties(struct stat stats)
{

// File permissions
printf("\nFile access: ");
if (stats.st_mode & R_OK)
printf("read ");
if (stats.st_mode & W_OK)
printf("write ");
if (stats.st_mode & X_OK)
printf("execute");
printf("\n File inode: %d \n",stats.st_ino);
printf("File size: %d \n\n", stats.st_size);

}
