@…ontribute for Hackertoberfest,Thanks

How It Works:

1. The progressbar_new function initializes the progress bar with a default width.

2. The progressbar_set_width function allows setting a custom width for the progress bar.

3. The progressbar_inc function increments the progress and displays the progress bar in the terminal.

4. The progressbar_finish function frees the memory used for the progress bar and finalizes the display.

Compile and Run:

1. Save the code in a file, e.g., progressbar.c.

2. Compile with:

gcc -o progressbar progressbar.c

3. Run the program:

./progressbar
