Explain the Interfaces in Ruby
Recall that in object-oriented programming, an interface is a collection of abstract operations that cannot be instantiated. Even though Ruby is object-oriented, it doesn't have interfaces. Interface-like classes can be constructed in Ruby by creating classes whose operations have empty bodies. These pseudo-interface classes can be used as super-classes of classes which implement the interface. Pseudo-interface classes can still be instantiated and their operations can still be known as without overriding them, so they are only a bit like real interfaces. One way to make them more like interfaces, though, is to implement the operations in pseudo-interface so that they raise exceptions if they are called. This forces sub-classes to override the operations in these pseudo-interface classes before they can be used.
Explain the Assertions in Ruby Ruby offers no support for assertions whatever. Moreover, because it's weakly typed, Ruby doesn't even enforce rudimentary type checking on opera
an electrical student designed a circuit in which the impedence in one part of a series circuit is 2+j8 ohms and the impedent is another part of the circuit is 4-j60 ohm mm program
Determine about the logic gates Many electronic circuits operate using binary logic gates. Logic gates essentially process signals that represent true or false or equivalent i.
