What will be the output of the following C++ code?

#include <iostream>
#include <string>
#include<typeinfo>
using namespace std;
int main( )
{
    try
    {
        string strg1("Test");
        string strg2("ing");
        strg1.append(strg2, 4, 2);
        cout << strg1 << endl;
    }
    catch (exception &e)
    {
        cout << "Caught: " << e.what() << endl;
        cout << "Type: " << typeid(e).name() << endl;
    };
    return 0;
}
