a, b) Public method defines that other methods can directly access the elements in the method. In other words, functions declared as public will be used, through calling, by clients to manipulate the class data, they cannot directly access the data hour, min, second because they are declared as private…
A constructor is constructed by the class in case it is not written by the programmer. In this case time() is the default constructor which will be used in case time( int hh, int mm, int ss) is not used.
a) Time ( ) and Time (int hh, int mm, int ss) are both constructors. Time() is the default that initializes random values in case Time (int hh, int mm, int ss) is not defined by the user in the program.
a) Encapsulation in object oriented programming is a technique that integrates data and operations to make an object. The benefits of encapsulation are abstraction and security. Abstraction in the sense that the operations and properties of an object are hidden from the outside world who is not bogged down with the inner workings of the object and security because the outside world can access the object only through its interface and does not have access to the inner workings of the object the outside world therefore cannot mess with the object.
d) Inheritance allows reusing previously defined classes. There are three benefits of inheritance use: (i) reuse of existing code from the base class, (ii) all children of the base class have the same methods and (iii) the programmer can redefine in the child class methods from the parent class.
e) "Signature" defines parameters overloading of the parents class. Functions' signature has to be unique to avoid confusion of overloaded parent class parameters.
Linear programming can be used for solving aggregate planning problem as the linear programming determines the optimal solution, minimizing the total costs, when the production capabilities, constraints on requirements, overtime, permitted workforces changes, sub-contracting limits and all the other related costs are given.
Programming languages Comparison and History. A computer program is simply is the process of abstraction of complexity to a user from a process. The program interface makes it easy for a user to be involved into a process and achieve his desired objectives.
Up till year 1974, The Department of Defense has used embedded software system applications to manage operations. In this scenario, an embedded software system is one in which the technology based computer hardware is implemented in the systems it controls.
There are two main skills that this software developer requires to have. These include the skills of Programming and that of Non-Programming. The skills associated with programming reflect on how good a software developer can design, code and test. The programming skills enable achievement of better performance and results.
The object oriented programming refers to a form of programming style or paradigm whose foundation is the representation of the programming concepts as objects. Each object in this form of interaction is referred to as an instance of a particular class of objects. In this paradigm, objects are those instances that are used to represent concepts.
A program or a comprehensive set of instructions that is designed to achieve a particular objective is referred to as a function or a method. These functions always work on related data. There are two paradigms that are followed to write computer programs: ‘procedural’ or
Computer codes developed through phases namely first generation code (machine language), second-generation code (assembly language) and third generation code (high level language). This discussion explores the history of computer programming over the years up to the
