LAB 2: In this lab we will focus on use of Classes. Example 1: Write C+ code to create class called car. The private data members for this class are price (float), name (string) and model (int). The member function for this class is: (Constructor) that accepts price, name and model as arguments (inside the class). Write a main() that create two objects (hl) with initially data members (price :13000, name:"accent" and model :2019), (kl) with initially data members (price :16000, name:"cerato" and model :2018). Finally print the name of the expensive car for these two objects using string expansive friend function:

LAB 2: In this lab we will focus on use of Classes. Example 1: Write C++ code to create class called car. The private data members for this class are price (float), name (string) and model (int). The member function for this class is: (Constructor) that accepts price, name and model as arguments (inside the class). Write a main() that create two objects (h1) with initially data members (price :13000, name:"accent" and model :2019), (kl) with initially data members (price :16000, name:"cerato" and model :2018). Finally print the name of the expensive car for these two objects using string expansive friend function: #include<iostream using namespace std; class car { private: float price; string name; int model; public: car(float p, string n, int m) { price p; name-n; model=m; friend string expensive(car, car); }; string expensive(car a,car b) string s; iffa.price> b.price) s=a.name; else s-b.name; return s; int main(){ car h1(13000, "accent", 2019); Object-Oriented Programming LAB. 2 asst. Lec. :Sura Nasser car kl(16000, "cerato", 2018); cout<< expensive(hl,kl); return 0; Exercise: 1- Modify the friend function in the example 1 to print the most expensive car among four cars 2- Define a class named Train' representing following members: Data members :- - Train Number - Train Name - Source - Destination - Journey time - Capacity Member functions - Initialise members - Input Train data - Display data Write C++ program to test Train class
