Self-Test Exercise 18 asked you to overload the operator >> and the operator << for a class Percent. Complete and test this exercise. Implement the default constructor and the constructor with one int parameter. Overload the + and − operators to add and subtract percents. Also, overload the * operator to allow multiplication of a percent by an integer. Write a

Each function should be coded in separate methods of the class. Give appropriate instance variables to implement the method. The user should be able to enter the string through the main function in Main class. Use a constructor to initialize the String entered by the user. Use the Main class to test all the methods in StringCheckclass. The programs should have the below given checklist: 1)Define classStringCheck with required instance variables 2)The StringCheck class should have six methods to do the below functions: *Check if the user entered string is a simple sentence? (Starts with capital letter, Ends with period, space between words). *Check if the user entered string is a question? (Check if the string starts with ac apital letter ends with a question mark, space between words) *Check if the user entered string have numbers in it? *Check if string is a valid email *Check…arrow_forwardWrite a Number class that holds a double, and add overloaded operators for +, –, *, /, and assignment.

- Write ONLY Header (No body{}) of function for each question. You can use any valid variable name for the input parameters. Assume that the following is a tester program of GameObject class, and answer the questions. int main (){ GameObject player (3, 100, 'M'); GameObject enemy (4, 100, 'F'); player.print(); } Guess the GameObject class and functions from the code above, and write the header of constructor. You can use any valid variable name for the input parametersarrow_forwardSolve This ASAParrow_forwardWrite a class Box having three private data members (width, depth, height) The class has three constructors which are having no parameter – for setting values to zero or null. having three parameters for assigning values to height, width, depth respectively. Overload the above constructor and use this keyword to set the values of width, height & depth. Provide getters/setters for data members. Write a function calculateVolume() which calculates the volume of the box. Write test Application that demonstrates the Box class by calling all the three constructors and method, creating a Create Box object, and then displaying the Box’swidth , height, length and volume .arrow_forward
- The following program contains a simple class that is designed to allow a user to enter an integer value within a specific range. The code prompts the user with a message that explains the limits of the valid range of values, but it does not force the user to enter legal values. We have examined a number of approaches for dealing with this problem. One approach is to place an assert statement in the getValue function to terminate the program when an illegal input occurs. An alternative approach is to put a loop inside the getValue function that prompts the user repeatedly until a valid value is received. Neither of these approaches is satisfactory, because they force the user to adopt a specific approach to dealing with the error. If you compare the execution of a program with the operation of a business, you will notice that both consist of a hierarchy of classes and functions. In a business, we expect the people in the upper layers of the company (managers) to set policies and the…arrow_forwardRedo Programming Exercise 3 by overloading the operators as nonmembers of the class boxType.
