When using the scanf function, we cannot simply specify the variable name. Rather, we have to prefix the variable name with an ampersand, e.g. int a; ...
Consider a C++20 program where in function foo there is a structured binding auto [y]. The function returns y, which is converted in object of type A. ...
In C++ it is impossible to bind an r-value argument to a non-const l-value reference. But I noticed that when I call on the r-value object the method ...
My code is as follows: When I compile the code shown above, I got some compile errors: It seems that the str in B::send function has been changed ...
I am not sure about some rvalue/lvalue non-trvial examples. are std::vector<int>({1,2,3})[0] and std::vector<int>() expressions below lva ...
We are creating a class designed to send information out from the current module (the specifics are not relevant to this question). An object of this ...
The compiler wants my lvalue to be a rvalue reference and I dont see why. My questions are: Why is "dataLen" const, even though it was declared n ...
The question related to this one. By tracing slt_pair. h and move. h, it's seems that the difference between Clang and G++ is internally. I have tried ...
Practically every example of lvalue-to-rvalue conversion I've seen on the web relates to fundamental types like int etc. I couldn't find an example o ...
From 6.3.2.1 (emphasis mine) If the lvalue designates an object of automatic storage duration that could have been declared with the register stor ...
I'm writing a C compiler which follows this standard, and if I parse statements like this: my compiler will report an error which point out that (i ...
Lets say you have 2 vectors passed to a function as lvalue references. Later you realize, you can use recursion and pass slices of these vectors using ...
Is a C implementation required to ignore undefined behaviors occurring during the evaluation of void expressions as if the evaluation itself never too ...
So I've been learning about rvalues and rvalue references and have run into some code while experimenting that I can't wrap my head around the errors ...
I need some reassurance about whenever, assigning or list initializing an auto typed named variable, with A a std::move()ed returned reference to ...
This is a question of terminology. If I have this: then what type is v? If you are talking about calling f0, you'd say "f0 takes an rvalue referenc ...
I am working on a project that deals with lots of atomic operations. Till now I didn’t knew about atomic_load() and was only relying on assignment ope ...
I encountered a problem where gcc compiler moved local variable (not temporary) as rvalue argument to a function. I have a simple example: The outp ...
EDIT: Sorry, I asked this question without a thro understanding of references... I seem to be getting this error when I run this code... error: inv ...
