1.Rename a file upon the user's request. If the file exists, prompt the user for confirmation before renaming the file. The screen should prompt the user for
a.“Name of file you want to rename.” Use the “\c” escape character.
b.“New name of file” Use the “\c” escape character.
Why use \c? It is not supported in many shells or systems.
Use printf instead.

c.“File Exist” to avoid overriding a file.
d.“File $oldname changed to $newname”
e.“Do you want to rename another file?” If the user selects “yes” the system should refresh the screen and if the user selects “no” the system should exit to the prompt sign.
f.Refresh the screen to go back to the menu until the user selects the exit option.
so far this is what i got so far, but im stuck and i dont know how to approach the rest of it.
If you can't do better than this, you'd better take the course over.
Did it not cover while loops?

load_dat_font
load_dat_font(3alleg4) Allegro manual load_dat_font(3alleg4)
NAME
load_dat_font - Loads a FONT from an Allegro datafile.
SYNOPSIS
#include <allegro.h>
FONT *load_dat_font(const char *filename, RGB *pal, void *param)
DESCRIPTION
Loads a FONT from an Allegro datafile. You can set param parameter to point to an array that holds two strings that identify the font and
the palette in the datafile by name. The first string in this list is the name of the font. You can pass NULL here to just load the first
font found in the datafile. The second string can be used to specify the name of the palette associated with the font. This is only
returned if the pal parameter is not NULL. If you pass NULL for the name of the palette, the last palette found before the font was found
is returned. You can also pass NULL for param, which is treated as if you had passed NULL for both strings separately. In this case, the
function will simply load the first font it finds from the datafile and the palette that precedes it.
For example, suppose you have a datafile named `fonts.dat' with the following contents:
FONT FONT_1_DATA
FONT FONT_2_DATA
FONT FONT_3_DATA
PAL FONT_1_PALETTE
PAL FONT_2_PALETTE
Then the following code will load FONT_1_DATA as a FONT and return FONT_1_PALETTE as the palette:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_1_DATA", "FONT_1_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If instead you want to load the second font, FONT_2, from the datafile, you would use:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_2_DATA", "FONT_2_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If you want to load the third font, but not bother with a palette, use:
FONT *f;
char *names[] = { "FONT_3_DATA", NULL }
f = load_dat_font("fonts.dat", NULL, names);
RETURN VALUE
Returns a pointer to the font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to
avoid memory leaks.
