When were Lvalue C ++ references introduced?
A google search on this subject returns articles for me with an emphasis on Rvalue links. My question is about Lvalue links (one, etc.).
In which version of C ++ were they introduced?
Links were presented in the first edition of the C ++ Programming Language in 1985, before the language was standardized.
But they have existed since it was renamed from "C with classes" to "C ++" in 1983.
