But only two objects are created (there are only two calls for constructor/destructor). // File constructors.cc #include <iostream> using std::cout; class TT { public: ~TT (void ) {cout << "D\n";} TT (void ) : c(' ') {cout << "C\n";} TT (char cc) : c(cc ) {cout << "C " << c << "\n";} char c; }; int main() { cout << "1\n"; TT(); cout << "2\n"; TT t2('a'); cout << "3\n"; TT t3(); // The object is not created!!! cout << "4\n"; TT t4; // OK! cout << "5\n"; } // EOF Output: $ ./a.out 1 C D 2 C a 3 4 C 5 D D So the object 't3' was not created.
