ls

The ls Command

ls lists the contents of a directory, sorted alphabetically. By default it skips hidden files — those whose names begin with a dot:

$ ls
Makefile  README.md  src  tests

Files like .git and .env are present on disk but not shown without the -a flag.

Your Implementation

Write void my_ls(const char *entries) that takes a newline-separated list of filenames (unsorted, may contain hidden files), skips any that start with ., sorts the rest, and prints them one per line.

This combines two operations you have already built:

1. Filter — skip entries whose first character is .
2. Sort — print the remaining entries in alphabetical order

void my_ls(const char *entries) {
    char lines[64][256];
    int count = 0;

    // Parse lines, skipping hidden files
    while (*entries) {
        char *out = lines[count];
        const char *start = entries;
        while (*entries && *entries != '\n') { *out++ = *entries++; }
        *out = '\0';
        if (*entries == '\n') entries++;
        if (start[0] != '.') count++;  // keep only non-hidden
    }

    // Bubble sort
    ...

    for (int i = 0; i < count; i++) printf("%s\n", lines[i]);
}

Your Task

Implement my_ls that filters hidden entries and prints the rest sorted alphabetically.
