String tokenizer function doubt

#1

why do we use a pointer while calling string tokenizer function. whereas we call other functions normally ???

#2

hey @chahatkumar, this is declaration of strtok function
char * strtok ( char * str, const char * delimiters );

You can clearly see that return type of this function is pointer, so it will return pointer only. Thatswhy we used pointer here.

#3

okay
but my question is that why the return type has to be pointer ??
can we use simply char as return type ??

#4

hey @chahatkumar, this is predefined function in c++ library, so we cannot change this.

#5

okay thanks :slight_smile:
