Problem with strings

[Pietervd]

I need to get strings to be compared semantically, but of course this can only work with strcmp. But I don't know how to compare two strings that aren't the same.
This is what I want (but of course it doesn't work since you can't compare them with == ! )

#define NWOORDEN	267
#define NTRIALS                     200

for (i = 0; i < NTRIALS; i++) {

do { int l =ts_rint(NWOORDEN); 
strcpy(data[i].prime,woord[l].woord);}
while ( 

(data[i].prime=="chinese" && (data[i].target == "tourist" || data[i].target == "places" || data[i].target == "person" || data[i].target == "germans" || data[i].target == "flemish")) 

|| (data[i].prime=="protest" && (data[i].target == "opstand" || data[i].target == "ontslag" || data[i].target == "vakbond" || data[i].target == "sanctie"))
							
|| (data[i].prime=="climate" && data[i].target == "oerwoud"))

}

I have a whole lot of words that have to be compared like this !

Anyone has an idea??

Thank you !!

I don't see anything here that would prevent you using strcmp()

You could write another function to compare one word against a list of other words, to simplify your code.

Post up a small example perhaps? It's not clear what the problem is.

Problem is that I have 267 words.
My script will print 2 random words on the screen (for example 'chinese' and 'protest').
This all works correctly.

But problem is that I have to tell the script that certain words can't be presented together. (for example 'chinese' and 'tourist)
So it will have to get another random word if that happens.

I want to use:
do ("get a random word ") while ( (1st word == "chinese" &&
2ndword == "tourist) || (1st word == "chinese" && 2nd word == "places") || ...

It's a lot of words that can't go together so it's quite a lot of lines of data.
But of course now that I've done it like this I can see that it doesn't work.

Reason for that is that you can't compare strings with ==

But I can't use strcomp() either I think because if I say for example
do("get a random word") while ((strcomp(1stword,2ndword)== ???)

What would I have to put where the question marks are? And won't that make sure that other words are also not chosen together(other than I want) ?

Hope that is a bit more clear

First, you need to build some kind of data structure, like say

struct wordpairs {
  char *word;
  int numAllowed;
  char **allowedPairs;
};

char *pairsForFred[] = { "Wilma", "Pebbles" };
char *pairsForBarney[] = { "Betty", "BamBam" };
struct wordpairs wordlist[] = {
   { "Fred", 2, pairsForFred },
   { "Barney", 2, pairsForBarney }
}

Now you could go the other way, for each word, you have a list of words it CAN'T be matched with. Use whichever gives you the shorter lists.

Having generated the first word, you search for it in wordlist[i].word.
Then you search for your second word in wordlist[i].allowedPairs[j]





As for your comparison, strcmp() returns == 0 if they match, and != 0 if they don't.

RTFM. either by google or man page...
eg

NAME
strcmp, strncmp - compare two strings

SYNOPSIS
#include <string.h>

int strcmp(const char *s1, const char *s2);

int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION
The strcmp() function compares the two strings s1 and s2. It returns
an integer less than, equal to, or greater than zero if s1 is found,
respectively, to be less than, to match, or be greater than s2.

Edit: yes salem approach is better.
