Dit is dus c, en geen c++

string1 en string2 zijn in feite const char*, en strok wil de " " in string1
(beter gezegd: de string waarnaar char* string1 verwijst) vervangen door een
NULL en probeert dus in read-only memory te schrijven met het bekende gevolg. 
Je kan misschien iets als strdup gebruiken om de string eerst te kopieren

dit moet f (isin(a,b) == 1) zijn
