Hi KuMan

K>I'm trying to read in strings from a file and put them in an array of
K>26 different cells according to their order alphabetically.

K>#include <stdio.h>
K>#include <stdlib.h>

K>void main(){

better: int     main( void ) {

K>FILE  *input;
K>char  name[20];
K>char  *stop_word[26];

K>input = fopen("QQ.txt", "r");
K>while(!feof(input)){
K>        fscanf(input, "%s", name);
K>        stop_word[((name[0] >= 97)? name[0]-96 : name[0]%64)] = name;

Here is the problem: You can't assign a character string as any ordinary type -
you must call a special function to do that. After this assignment every assign
entry of stop_word will contain a pointer to name, which has the value of the
last string read.

To put this right, you could replace the original line by the following:

    stop_word[((name[0] >= 97) ? name[0]-96 : name[0]%64)] =     strdup(name);

K>}
printf("%s \n", stop_word[1]);
printf("%s \n", stop_word[3]);
}
fclose(input);
}
