[section References]
|
|
|
|
References are functions. They hold a reference to a value stored somewhere.
|
|
For example, given:
|
|
|
|
int i = 3;
|
|
char const* s = "Hello World";
|
|
|
|
we create `references` to `i` and `s` this way:
|
|
|
|
ref(i)
|
|
ref(s)
|
|
|
|
Like `val`, the expressions above evaluates to a nullary function; the first one
|
|
returning an `int&`, and the second one returning a `char const*&`.
