Truncating a string while storing it in an array in c
- by Nick
I am trying to create an array of 20 character strings with a maximum of 17 characters that are obtained from a file named "words.dat". After that the program should truncate the string only showing the first 17 characters and completely ignore the rest of that string. However
My question is: I am not quite sure how to accomplish this, can anyone give me some insight on how to accomplish this task?
Here is my current code as is:
#include <stdio.h>
#include <stdlib.h>
#define WORDS 20
#define LENGTH 18
char function1(char[WORDS][LENGTH]);
int main( void )
{
char word_array [WORDS] [LENGTH];
function1(word_array);
return ( 0 ) ;
}
char function1(char word_array[WORDS][LENGTH])
{
FILE *wordsfile = fopen("words.dat", "r");
int i = 0;
if (wordsfile == NULL)
printf("\nwords.dat was not properly opened.\n");
else
{
for (i = 0; i < WORDS; i++)
{
fscanf(wordsfile, "%17s", word_array[i]);
printf ("%s \n", word_array[i]);
}
fclose(wordsfile);
}
return (word_array[WORDS][LENGTH]);
}
words.dat file:
Ninja
DragonsFury
failninja
dragonsrage
leagueoflegendssurfgthyjnu
white
black
red
green
yellow
green
leagueoflegendssughjkuj
dragonsfury
Sword
sodas
tiger
snakes
Swords
Snakes
sage
Sample output:
blahblah@fang:~>a.out
Ninja
DragonsFury
failninja
dragonsrage
leagueoflegendssu
rfgthyjnu
white
black
red
green
yellow
green
leagueoflegendssu
ghjkuj
dragonsfury
Sword
sodas
tiger
snakes
Swords
blahblah@fang:~>
What will be accomplished afterwards with this program is:
After function1 works properly I will then create a second function name "function2" that will look throughout the array for matching pairs of words that match "EXACTLY" including case . After I will create a third function that displays the 20 character strings from the words.dat file that I previously created and the matching words.
