Textbook Question
Chapter 15.1, Problem 3STE
Is the following a legal definition of the member function isCrazy in the derived class SmartBut discussed in Self-Test Exercise 2? Explain your answer. (Remember, the question asks if it is legal, not if it is a sensible definition.)
bool SmartBut::isCrazy( ) const { if (a > b) return false; else return true; } |

Write down code that can declare a class of an employee with the properties, name and salary, and the methods, getSalary and getName, that return the salary and name of the employee respectively. Function members should be declared as prototypes only andinclude a parameterised constructor prototype to initialise with the name and salary.
In three sentences, explain why it's preferable to have accessors for private types rather than public types.

- This chapter uses the class rectangleType to illustrate how to overload the operators +, *, ==, !=, >>, and <<. In this exercise, first redefine the class rectangleType by declaring the instance variables as protected and then overload additional operators as defined in parts 1 to 3. Overload the pre- and post-increment and decrement operators to increment and decrement, respectively, the length and width of a rectangle by one unit. (Note that after decrementing the length and width, they must be positive.) Overload the binary operator – to subtract the dimensions of one rectangle from the corresponding dimensions of another rectangle. If the resulting dimensions are not positive, output an appropriate message and do not perform the operation. The operators == and != are overloaded by considering the lengths and widths of rectangles. Redefine the functions to overload the relational operator by considering the areas of rectangles as follows: Two rectangles are the…arrow_forwardExplain why it is better to have accessors for private types rather than public types in no more than three sentences.arrow_forwardExplain why accessors to private types are preferable than make the types public for the following three reasons.arrow_forward
- Justify why it is desirable to have accessors to private types rather than making the types public for the following three reasons.arrow_forwardCan you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"arrow_forwarda. Extend the definition of the class complexType so that it performs the subtraction and division operations. Overload the operators subtraction and division for this class as member functions. If (a, b) and (c, d) are complex numbers, (a, b) - (c, d) = (a - c, b - d), If (c, d) is nonzero, (a, b)/(c, d) = ((ac + bd)/(c ^2+ d ^2 ), (-ad + bc)/(c ^2 + d^ 2 )) b. Write the definitions of the functions to overload the operators – and / as defined in part a. c. Write a test program that tests the various operations on the class complexType.
