C++ exception Handling

Hello all expert C++ programmer, sorry to post here. I have a stupid question about C++ exception handling.

How many types of exception handling in C++?

Below is my code :
Code:
// Exception Handling Program
// Exception Specification

#include<iostream>
#include<exception>

using namespace std;

int add(int, const int &

throw (const char *);
int main(int argc, char *argv[])
{
int number = 5, user;
const int &reference = number;
// Reference must be initialized

while(1)
{
try
{
cout << "\nEnter a integer : ";
cin >> user;
cout << "The result is " << add(user, reference);
}
catch(const char * msg)
{
cout << cout << "Oops, caught: " << msg << endl;
}
}

return 0;
}

int add(int user, const int &reference)throw (const char *)
{

if (user == 0 )
throw(const char *)"Cannot enter zero";

return user + reference;
}
I got a warning message from the MS visual studio 2005 compiler as below.

I dont't understand what it's mean. Thanks for your explanation.
