Merge 3 files in 1 file in an ordered way
Hi, I have a question that I cannot solve.
if I have a file like this (lets say "x-values.dat"):
x1
x2
x3
another file like this (lets say "y-values.dat"):
y1
y2
y3
y4
and another file like this (lets say "p-values.dat"):
p1
p2
p3
...
p12
How can I get this output?
x1 y1 p1
x1 y2 p2
x1 y3 p3
x1 y4 p4
x2 y1 p5
x2 y2 p6
x2 y3 p7
x2 y4 p8
x3 y1 p9
x3 y2 p10
x3 y3 p11
x3 y4 p12
Any help would be much appreciated

load_datafile
load_datafile(3alleg4) Allegro manual load_datafile(3alleg4)
NAME
load_datafile - Loads a datafile into memory. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
DATAFILE *load_datafile(const char *filename);
DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate
key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example:
/* Load the resources for our game. */
DATAFILE *dat = load_datafile("game.dat");
if (!dat)
abort_on_error("Couldn't load sound resources!");
/* Use resources. */
...
/* Destroy them when we don't need them any more. */
unload_datafile(dat);
RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks.
