- It should print on the terminal, the names of all the files within the same directory and indicate the state of each file (each one on a separate line). The state can be ‘ASCII' or ‘Undefined’. Assume ASCII is 7 bits.
- All ASCII files should be encrypted using shift cipher and the provided key . The result of each encryption should be saved to a new file called
filename.cipher
Here is what I have tried
#include <stdio.h>
#include <dirent.h>
int main(void)
struct dirent *de; // Pointer for directory entry
// opendir() returns a pointer of DIR type.
DIR *dr = opendir(".");
if (dr == NULL) // opendir returns NULL if couldn't open directory
printf("Could not open current directory" );
return 0;
// for readdir()
while ((de = readdir(dr)) != NULL)
printf("%sn", de->d_name);
closedir(dr);
return 0;

Good to see what you have tried. Can you tell us a little more about what you are trying to do? And does it have to be inC?

You have more than one question here. You seem to be stuck on iterating through the files.

Do one thing at a time. What is the next useful thing that the program could do? You seem to be stuck on iterating through the files. Write a program that does this, and displays the names, and test it. Then ask “what is the next useful thing that this program should do?” etc etc

The question is clear, but there are too many. (one question per question)

The next step is to open each file and read every character and check if any character has its 8th bit on. Do you know how to start that?
