reading from a text file

[slickn_sly]

I'm trying to read a text file and storing each line to a specific
array.
so if i define an array - name, address,... and in my text file I have
something like:

John Doe
Seattle, Washington

Julie Walsh
New York, New York

I wanna store the names into the name array and the addresses into the
address array. Anybody have any ideas?

Hmmm, that sounds like a question from an introductory programming
class.

Is there a given maximum size for the number of name/address pairs?
Is there a given maximum size for each name? For each address?

Generally speaking, you start by allocating the name and address
arrays. There will be several entries for each, and each -entry-
is a string. But a string is an array of characters, so you are in
effect going to need a pair of two-dimensional arrays. You can put
that into effect in more than one way, one of which is conceptually
simple and the other of which is much more efficient.

First, get and compile the source to ggets, which is available at:

<http://cbfalconer.home.att.net/download/ggets.zip>

and contains only portable standard C. Then you can write your
code and link in ggets.o. The code will probably be something like
(untested):

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

#define MAXGUYS 25 /* or whatever floats your boat */

int main(void)
{
int ix, iy;
char *name[MAXGUYS]
char *address[MAXGUYS];
char *blankline;

ix = 0;
while ((0 == ggets(&name[ix]) && (0 == ggets(&address[ix]))) {
if (++ix >= MAXGUYS) break;
if (0 == ggets(&blankline)) free(blankline);
else {
puts("Badly formatted input file");
break;
}
}
for (iy = 0; iy < ix; iy++) {
printf("%s\n%s\n\n", name[iy], address[iy]);
free(name[iy]); free(address[iy]);
}
return EXIT_SUCCESS;
} /* main, untested */
