In C++ the declaration of floating point variables starts with the type name float or double, followed by the name of the variable, and terminates with a semicolon. It is possible to declare multiple variables separated by commas in one statement. The following statements present examples, float z; double z, w; The following partial grammar represents the specification for C++ style variable declaration. In this grammar, the letters z and w are terminals that represent two variable names. The non-terminal S is the start symbol. S=TV; V=CX X = , VIE T = float double C = z w 1 - Determine Nullable values for the LHS and RHS of all rules. Please note, your answer includes all Nullable functions for LHS and RHS, in addition to the resulting values. (25 points)

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
