Count words in a string

Hello,

I'm looking for a way to count a specific word in a string, here's an example of what I've written

Code:

---

char TextString[]="hello this is a test string, used used used to count specific words";
char *StringToSearch[3]={"this","a", "used"};
 int this_count=0, a_count=0, used_count=0;

---

So I want to put in a loop and look for these words, I was thinking of using strstr function, but that just looks the strings once.

Do you have a solution?

Have a moving pointer so you can search the rest of the string after you find a match. Something like:

Code:

---

char *str, *match;
int count = 0;
for(str = TextString;str;str = match == null ? match : match + strlen(StringToSearch[index]))
  if((match = strstr(str, StringToSearch[index])))
    count++;
