uncaught_exception.cpp

#include <iostream>
#include <string>

class Foo
{
    const std::string str;
public:
    Foo(const std::string &str_) : str{str_} {}
    ~Foo() { std::cout << str << " Foo's dtor called." << std::endl; }
};

Foo gfoo {"global"};
static Foo sgfoo {"static global"};

int main()
{
    try {
        Foo lfoo {"local stack"};
        throw int(123);
    } catch (char) { // Change to int in order to catch the exception
        std::cout << "Exception catched." << std::endl;   
    }
    return 0;
}
