can tell me what wrong i did?
There is no variable called 'count' in main().
oh yes thanks... i solved it.. thanks though.. btw can i ask how to assign a string to a variable???
You would need to #include <string> first, then you can just do something like:
std::string my_string = "some string data";
ok thanks
