    Code:
    #include <iostream>
    #include <limits>
    using namespace std;
    int main(void)
    {
    numeric_limits<double> doubleLim;
    cout<<doubleLim.max()<<endl;
    cout<<numeric_limits<double>::is_signed;
    //...etc
    }

    Show us the errors. Our psychic abilities do have limits. And you might want to add an } at the end.
