Thanks for the question Nagasanthoshi, Lvalue is something that can stand on the left side of an assignment. In most of the cases it is the variable name where the value gets stored. Thanks, Team DishaaPro www.dishaapro.com

Hi Nagasanthoshi, see this statement; a = b. Here, we have assigned 'b' to 'a'. Since 'b' is coming on right hand side it is called as rvalue and 'a' is coming on right hand side, it is called as rvalue.

Lvalue is the value which appears to the left side of the mathematical expression

Pretty simply, an rvalue is when the expression result will not survive past the end of said expression. An lvalue will. This basic principle is what enables move semantics and rvalue references- that you can modify them without issue, because you know that object's life is over.
