I'm trying to make A code for my AI to search a database of predetermined code snippets that it can use to write its own code. Maybe @ZahirSher or @shmoo or @DiDA could help please. Like where did I mess up? The error said- invalid code and didn't give me a line. Here is the code:

 

const char *kmp_search(const char *text, const char *pattern)
{
    int *T;
    int i, j;
    const char *result = NULL;
 
    if (pattern[0] == '\0')
        return text;
 
    /* Construct the lookup table */
    T = (int*) malloc((strlen(pattern)+1) * sizeof(int) );
    T[0] = -1;
    for (i=0; pattern != '\0'; i++) {
        T[i+1] = T + 1;
        while (T[i+1] > 0 && pattern != pattern[T[i+1]-1])
            T[i+1] = T[T[i+1]-1] + 1;
    }
 
    /* Perform the search */
    for (i=j=0; text != '\0'; ) {
        if (j < 0 || text == pattern[j]) {
            ++i, ++j;
            if (pattern[j] == '\0') {
                result = text+i-j;
                break;
            }
        }
        else j = T[j];
    }
 
    free(T);
    return result;
}
