This post What are rvalues, lvalues, xvalues, glvalues, and prvalues? provides the definitions of rvalue, lvalues, xvalues, glvalues, and prvalues, but I don't see examples.
I think I have a solid understanding of lvalues and rvalues, but not so much of xvalues, glvalues, and prvalues. Examples (code) of each and their differentiation would really help.
