the find member function

Code:

---

#include < iostream >
#include <  string  >
using namespace std;

int main()
{
        string greeting = "hello";

        cout << greeting.find ( 'c', 0 ) << endl;

        return 0;
}

---

Since c isn't in the word hello, shouldn't that cout statement print out -1? Why is it printing out 4294967295?

Failure to find the item results in a return value of string::npos, not -1.

What's string::npos? Where did that come from?

The answer is here

Oh...and 4294967295 in hex is 0xFFFFFFFF (32 bit int) which is the same as -1.......

A good example of what can happen when you display a signed number as an unsigned int !!!
