lvalue in Technology

A reference to a location, an expression which can appear as the destination of an assignment operator indicating where a value should be stored. For example, a variable or an array element are lvalues but the constant 42 and the expression i+1 are not. A constant string may or may not be an lvalue (it usually is in C).
