Hi, this questions puzzles me the last days and I hope I do not overlook the obvious... but when we create a setter (also with the "create getter and setter" quick fix) we write
void setFoo(int foo); but not void setFoo(CONST int foo); Why? If int would not be a POD, we would pass a const reference mainly to avoid the costs of passing by value. This, of course, is not necessary for an integer. The second aspect, however, is that we promise the caller, we wont change the argument, - which is also not needed if we pass the argument by value - but it also protects us from accidentally changing the argument's value. With setFoo(int foo) we forgo this aspect. Additionally when we create a local variable in a function, we declare it const. Again, to protect us from accidentally changing it, but also that the compiler can put this variable into the read only section to gain speed/performance etc. Does that not also apply to an argument?
