Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.
