Determining the Largest number??

Where Can i found information on determining the largest positive, whole value that a int, unsigned int, long, unsigned long, float, and double can hold?

In limits.h.

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
}

---

does not compile in linux

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;

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