Thread: strstr Question

I'm reading through an array, and i wanted to count the number of occurences that a certain word appears for instance if the user wants to count how much times "the" appears in the array. Umm i came about the strstr function from the string library, but im not sure if it could be used for that. Can it?

The aim is to count number of occurences of a word

I was thinking something like this, cept i think my logic is crap based on it. Im reading that it returns a pointer to the current location from where the word begins. see

Code:

         if(strstr(buffer,word)!=NULL){
         ++count;}

was trying that but if its a pointer to the location, then i believe it would stop right at the first encounter right?

Yes, you'll have to add some amount to the returned pointer and keep iterating through your string.

Ok thanks. Good to know it can work, ill go work on those statements.
