Lvalue and Rvalue Overloads of a Template

Write two overloads of a function template identify:

- identify(T& value) prints Lvalue and a newline - identify(T&& value) prints Rvalue and a newline

An lvalue is an expression that names a place you could assign to, such as a variable; an rvalue is a temporary result, such as a literal or the value of an addition. When both overloads could match, the T& version wins for lvalues, and the T&& version is the only match for rvalues. The tests start with int x = 5; and call identify with x, with 10, with x + 1, with ++x (pre-increment gives back the variable itself) and with x++ (post-increment gives back a temporary copy), then print x, so six lines are printed.

Do NOT write a main function.

Expected Output:

Lvalue↵
Rvalue↵
Rvalue↵
Lvalue↵
Rvalue↵
7↵

= newline. The output ends with a newline — print one after the last line.
