i'm working through chapter 18 of stroustrup's principles , practice , stuck on 1 part related copy constructors. i have copy constructor defined as: x(const x& x) { out("x(x&)"); val = x.val; } x struct. val int value of x. 'out' is: void out(const string& s) { cerr << << "->" << s << ": " << val << "\n"; } i have following 2 functions defined: x copy(x a) { return a; } and x copy2(x a) { x aa = a; return aa; } in main have: x loc(4); x loc2 = loc; loc2 = copy(loc); loc2 = copy2(loc); when call copy, copy constructor called twice: once copy's parameter scope , once return call. makes sense me. however, when call copy2, copy constructor still called twice: once function argument , once 'x aa = a.' why isn't called return? there's no guarantee copy constructors called in c++. in case of return, it'...
