Solved in 2 steps with 1 images
- Create a class Distance having a member meter. Now create a friend function named convert() that increments meter by 5 and then convert that meter in kilo meters and return the answer. Call the function in main. Note: use OOP and C++Assume that class B is derived publicly from class A. Class A has two functions, f1() and f2(). Function f2() is virtual. Assume the following statements statements:A* ptr=new B; ptr->f1(); ptr->f2(); Fill in the blank.The function f1() as defined in class ____ will be used. The function f2() as defined in class _____ will be used. In question 1, the call to ptr->f2() is an example of _______________________.Write a code in the main function that would call Function 1 and Function 3 of the Lab class. You can use values of your choice for function arguments (if required). Please write the output of these function calls. class Lab { int time; public: Lab(){ //Function 1 time = 120; cout << "Duration of lab is " << time << “minutes” << endl; } void Demonstration(){ //Function 2 cout << "Lab Demonstration started." << endl; } Lab(int duration){ //Function 3 time = duration; cout << "Duration of lab is " << time << “minutes” << endl; } ~Lab(){ //Function 4 cout << "Thanks. Lab has ended." << endl; } };
- Describe scenarios where passing function objects as arguments can be beneficial.task1: write a void function divisor that receives an integer number and display its divisor on screen including 1 and itself. write the main function to test your function. task2: You are required to create a conversion program. First ask the user his choice and then convert. • Conversion from Pound to Kg. (1 Pound = 0.453 Kg) • Conversion from Feet to centimeter (1 Foot = 30.48 cm) • Convert Hours & minutes in DaysShould define a main function and end by invoking it
- The return type ________ indicates that when a function completes its task, it does not return (i.e., give back) any information to its calling function. Question 5 options: A) virtual B) null C) nullptr D) voidEach function inside the class A(n)_ is a virtual function. Provide your thoughts by filling in the blanks.14. Assume that class B is derived publicly from class A. Class A has two functions, f1() and f2(). Function f2() is virtual. Assume the following statements statements: A* ptr=new B; ptr->f1(); ptr->f2(); Fill in the blank. The function f1() as defined in class ____ will be used. The function f2() as defined in class _____ will be used. 15. In question 14, the call to ptr->f2() is an example of _______________________.
- Using C++ Create a class named employee with name(type string) and points (type double). Include a two-argument constructor for initializing the name and points. create a static function named getBest that receive array of 5 objects and find and return the object with maximum points.Create Class Date with variables day,month,year and a function display() and another class Time with variables hour,minutes,seconds and a function display(). Now create a third class named Time_Date it will inherit from both Classes Date and Time it should have a function display() which will display time and date.Question No. 2 Write a program that takes input values as integer, checks the number is not less than 10 (otherwise take input again) and prints the previous 10 numbers i.e. 10, 9, 8, … Concatenate the integer and string values and print as a string Write code to create a class named as ‘Employee’ with attributes i.e. ID, Name, Designation, Qualification, Salary, Taken-Leaves, Allowed-Leaves and the functions applyLeave(). This function will take number of leaves as an input and check Allowed-Leaves to see whether the employee can take leaves or not. If he can take, deduct these leaves from Allowed-Leaves and add in Taken-Leaves. Otherwise show message ‘you cannot take leave’. Create another class ‘Intern’ and inherit ‘Employee’ as super class.
