Consider the following grammar and the semantic actions to support the inherited type declaration attributes. Let X1, X2, X3, X4, X5 and X6 be the placeholders for the non-terminals D, T, L or L1 in the following table: Production rule Semantic action D → T L X1.type = X2.type T → int T.type = int T → float T.type = float L → L1, id X3.type = X4.type addType(id.entry, X5.type) L → id addType(id.entry, X6.type)   Which one of the following are the appropriate choices for X1, X2, X3 and X4?

Consider the following grammar (that admits a series of declarations, followed by expressions) and the associated syntax directed translation (SDT) actions, given as pseudo-code: P → D* E* D → int ID {record that ID.lexeme is of type int} D → bool ID { record that ID.lexeme is of type bool} E → E1 + E2 {check that E1.type = E2.type = int; set E.type := int} E → !E1 {check that E1.type = bool; set E.type := bool} E → ID {set E.type := int} With respect to the above grammar; which one of the following choices is correct?
A water tank has two types of inlet pipe viz. Type A and type B. 5 inlet pipes of type A and 25 pipe of type B are opened, the tank is filled in 30 minutes.

Kha-kha is an obscure island which is inhabited by two types of people: the "Yes" type and the "No" type. A native of type 'yes' ask only questions and right answer to which is 'Yes' while those of type 'No' ask only questions the right answer to which is 'No'.
