这也正是C++之父的建议。 Be suspicious of non-const reference arguments; if you want the function to modify its arguments, use pointers and value return instead. ---Bjarne Stroustrup《the C++ programming language》 (6)再来看个奇怪的函数。 1 2 3 4 5 6 classa_class{ intdata1; intdata2;...
4. Using Const with Function Arguments In C++, the const keyword can be used with function arguments to indicate that a function does not modify the value of the argument. When a function argument is declared as const, it cannot be changed within the function. This helps to prevent unintenti...
Always write const in “postfix”, on the right-hand side of the type it is qualifying. That you can write const int is a quirk of the C syntax which should not exist.)How does int const differ from int? A value of type T const cannot be assigned to, except when initialized. For...
Constant is something that doesn't change. In C language and C++ we use the keyword const to make program elements constant. const keyword can be used in many contexts in a C++ program. It can be used with: Variables Pointers Function arguments and return ...
Theconstexprspecifier declares that it is possible to evaluate the value of the entities at compile time. Such entities can then be used where only compile timeconstant expressionsare allowed (provided that appropriate function arguments are given). ...

This leaves us with the question of how to pass arguments into a function. While they may not be entirely perfect, the following two rules should apply in most cases: If you just need to look at the argument: Pass by const reference. If you need to make a copy anyways, pass by ...
