Holy shit who's teaching you C++? The man should be fired.

#include<iostream.h>
#include<string.h> 

should be

#include<iostream>
#include<string> 

main()

should be

int main()

Also you either need using namespace std; after your includes or put a std:: before all identifiers from the standard library.

As to your specific problem - this should probably be

rev_str(str+1);

But C strings are the devil anyways. We have std::strings for that. Also, put {} braces around your two statements, else you will cout the \0 character as well - that probably won't break anything, but that's not a printable character anyways.

rev_str(str+1);


Undefined symbol in 'str' function rev_str(char *)

whats up with that line how can i define it . .

Change that to s.
