In this program, we will read the name of the empty directory, and then will remove the given empty directory using the system() function by specifying the "rmdir" command.

Program:

The source code to remove an empty directory using the system() function is given below. The given program is compiled and executed using GCC compile on UBUNTU 18.04 OS successfully.

//C program to remove an empty directory
// using the system() function

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char dirName[16];
    char cmd[32] = { 0 };

    int ret = 0;

    printf("Enter directory name: ");
    scanf("%s", dirName);

    sprintf(cmd, "rmdir %s", dirName);

    ret = system(cmd);

    if (ret == 0)
        printf("Given Empty directory deleted successfully\n");
    else
        printf("Unable to delete directory %s\n", dirName);

    return 0;
}

Output:

RUN 1:
Enter directory name: empty
Given Empty directory deleted successfully

RUN 2:
Enter directory name: hello
rmdir: failed to remove ‘hello’: No such file or directory
Unable to delete directory hello

Explanation:

Here, we created a character array dirName. Then we read the name of the directory from the user. And, we removed the empty directory using the system() function. The system() function is used to execute the command. Here we created a command using the sprintf() function. Then we pass the created command in the system() function and removed the given empty directory. After that, we printed the appropriate message on the console screen.
