Difference between Interface and Class : Interface supports multiple inheritance whereas a Class does not support multiple Inheritance.

(b) Convert the following infix expression to postfix form: P * Q / R + (S + T) [2]

(b) Infix to postfix :

P*Q/R+(S+T)

= P*Q/R+ ST+

= PQ* /R + ST+

= PQ*R/ + ST+

= PQ*R/ST++
