    So you basically want to stop using std::string and std::vector, and instead use c-style strings and arrays?

    Well it will work. But why on earth would you want to do that? Stay with std::vector...

    Re: pointer question in C

    p[0] != p but *p

    p[1] != p+sizeof(data_type) but rather *(p+1).

    Also... p+sizeof(data_type) would only be the same address as p++ if data_type is char....

    The obious thing to do, would be to simply move the definition of a into the for-loop's curlies. That way it will be constructed/destructed each iteration. (Giving you an empty stream each time)

    Re: Thank everyone

    Is there any perticular reason you are using a char[10] and not a std::string?
    std::string Result;
    std::string Str("Hello Gurus, good day!");
    int n = 10;

    Result = Str.substr(Str.size() - n , n);

    array[i] = i;
