    Issue with Binary Search function

    Afternoon guys. I have written the function listed below. It is a binary search function that is supposed to search through a 2d array (dict) for a word (word).

    My issue is that with both strcmp commands, I receive the error "passing argument 1 of 'strcmp' makes pointer from integer without cast." I googled it, but I didn't come up with any concrete answers. Thanks.

    Code:
    int binsearch (char dict[][19], int maxWords, char word) {
    
    int low = 0;
    int high = maxWords-1;
    int FOUND = 0;
    
    while (low <= high) {
    
        int mid = (low + high)/ 2;
    
        if ((strcmp(word,dict[mid])) < FOUND)
            high = mid-1;
    
        else if ((strcmp(word,dict[mid])) > FOUND)
            low = mid+1;
    
        else
            return 1;
    
        }
    
    return 0;
    
    }

    "word" is a character, not a null-terminated array of characters (string).

    Thanks. I have changed word to word[]. It's always something small that I've overlooked. Thanks.
