If (Rvalue == LValue)

Understanding lvalues and rvalues in C and C++ - rvalues are defined by exclusion, by saying that every expression is either an lvalue or an rvalue. Therefore, from the above definition of lvalue, an rvalue is an expression that does not represent an object occupying some identifiable location in memory.

lvalue and rvalue in C language - A r-value is an expression that can't have a value assigned to it which means r- value can appear on right but not on left hand side of an assignment operator(=).

Value categories - an lvalue (so-called, historically, because lvalues could appear on the left-hand side of an assignment expression) is a glvalue that is not an xvalue; an rvalue (so-called, historically, because rvalues could appear on the right-hand side of an assignment expression) is a prvalue or an xvalue.
