Or, search for the error or warning number on the Visual Studio C++ Developer Community site. You may find additional assistance for errors and warnings in Microsoft Docs Q&A forums. In Visual Studio, go to the menu bar and choose Help > Send Feedback > Report a Problem, or submit a suggestion by using Help > Send Feedback > Send a Suggestion. You can also send feedback and enter bugs within the IDE. If you think the error or warning is wrong, or you've found another problem with the toolset, report a product issue on the Developer Community site. You can use the feedback buttons on this page to raise a documentation issue on GitHub. If you landed on this page when you used F1 and you think the error or warning message needs additional explanation, let us know. In many cases, the diagnostic message provides all of the information that's available. Yet, if a is an object of class Array, most people think that a = 7 makes sense even though a is really just a function call in disguise (it calls Array::operator(int), which is the subscript operator for class Array).Not every Visual Studio error or warning is documented. For example, no one thinks the expression f() = 7 makes sense. The function call can appear on the left hand side of an assignment operator. In compiler writer lingo, a reference is an “lvalue” (something that can appear on the left hand side of an assignment operator). Remember: the reference is the referent, so changing the reference changes the state of the referent. You change the state of the referent (the referent is the object to which the reference refers). What happens if you assign to a reference? There is no C++ syntax that lets you operate on the reference itself separate from the object to which it refers. It is neither a pointer to the object, nor a copy of the object. A reference is the object, just with another name. Important note: Even though a reference is often implemented using an address in the underlying assembly language, please do not think of a reference as a funny looking pointer to an object. In other words, a C programmer will think of i as a macro for (*p), where p is a pointer to x (e.g., the compiler automatically dereferences the underlying pointer i++ is changed to (*p)++ i = 7 is automatically changed to *p = 7). If you used the C style pass-by-pointer, with the syntactic variant of (1) moving the & from the caller into the callee, and (2) eliminating the *s.
In particular, the address bits that the compiler uses to find x are not changed. But when the programmer says i++, the compiler generates code that increments x. Underneath it all, a reference i to object x is typically the machine address of the object x. Now, at the risk of confusing you by giving you a different perspective, here’s how references are implemented. That’s how you should think of references as a programmer. Anything you do to i gets done to x, and vice versa. In other words, i is x - not a pointer to x, nor a copy of x, but x itself. Here i and j are aliases for main’s x and y respectively.
References are frequently used for pass-by-reference: void swap(int& i, int& j) An alias (an alternate name) for an object.
