OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step
Solved in 2 steps
- The this pointer is accessible (i) Within all the member functions of the class (ii) Only within functions returning void (iii) Only within non-static functions (iv) Within the member functions with zero argumentsA(n)_ is a class that only has pure virtual functions. Fill in the blanks with your response.To overload the pre-increment operator for a class as a member function, how many arguments are required? b.When overloading the pre-increment operator for a class as a friend function, how many arguments are required?
- C++ The class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class. Input should be format month day year with each separated by a space. If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a message indicating that it is not a leap year. Header file: #ifndef date_H #define date_H class dateType { public: void setDate(int month, int day, int year); //Function to set the date. //The member variables dMonth, dDay, and dYear are set //according to the parameters…Functions that take no parameters by default need a description of the applicable rules.True or false? Only instance member functions can be defined as constant functions.
- The distinction between a class's static and non-static data members is as follows: Give an example of real-world application where you think a static data member would be useful.State if true or false: Dynamic binding with virtual functions occurs only with pointers and referencesC++ The class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class. Input should be format month day year with each separated by a space. If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a message indicating that it is not a leap year. header file should have bool isLeapYear();
- Local declarations are those that are kept in the memory of the computer; but, how exactly are they kept in memory? If reaching one's objective can be done without making use of local declarations, then doing so is a waste of time. Why bother using value parameters when you can just use references as your arguments in any function? How crucial are value parameters when it comes to the processing of programmed data?Both child class and its parent class have same function signature. Which version of function will be called by the object pointer of parent class that is pointing to the child class’s object? Explain the reason. When do we need to use virtual function? Explain with example programThe static data members and static member functions aren't quite what I'm going for in this particular instance.
