n C++ Call your class quadraticExpression. • Your private data will be a, b, c. Make them doubles. • Create an enumerated list with o NO_ROOTS = 0 o ONE_ROOT = 1 o TWO_ROOTS = 2 o INFINITE_ROOTS = 3 • Write the constructor as stated in the book • Write the changeCoeeficients as stated in the book • Write the getACoeeficient, getBCoeeficient, getCCoeeficient as inline constant functions • Write evaluate function to take a double a return a double. Constant function. • Write getNumberOfRoots function to return an integer. Constant function. • Write getFirstRoot and getSecondRoot to return the first and second roots. Return a domain_error is there is no first or second root. Constant Functions. Use my .cpp file to test out your class

IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class.   Once you ask the points of any shape it will display in the terminal the points added.

IN JAVA PLEASE, need help finding an element in the list     /**     * Returns whether the given value exists in the list.     * @param value - value to be searched.     * @return true if specified value is present in the list, false otherwise.     */     public int indexOf(int value) {        //Implement this method                return -1;    }

In Kotlin, use this Employee class Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called formatPaycheck that takes a Pair and returns a String. formatPaycheck should use the two parts of the Pair to put together and return a String like this, with the paycheck amount shown to two digits past the decimal point: Pay to the order of Cathy $359.47 Use raise() to raise all the Employees' pay by 15%. Then use map with the payroll and formatPaycheck functions to get a list of the paychecks in the format shown above. Print the result. The output should look like this: [Pay to the order of Bob $1077.79, Pay to the order of Cathy $359.47, Pay to the order of Carlos $1361.09, Pay to the order of Tomas $1056.09,…
