Purpose and Aim

3.

The aim of this assignment is to provide a learner an opportunity to apply the knowledge and skills gained in class to analyze and design a real world object oriented solution to the problems.

Scenarios

4.

Apply Object Oriented concepts and solve all the given problems.

4.1

Problem No.1

Imagine a tollbooth at a motorway. Cars, trucks, coasters, wagons, containers and oil tankers are passed from this booth. When cars, wagons and coasters are passed they pay Rs100/- and when trucks, containers and oil tankers are passed they pay Rs 200/-. Keep the record that how many cars, wagons, coasters, containers, trucks and oil tankers are passed and how much total money is collected for one day. Model this tollbooth with a class. Design the data members that hold the total no of cars, wagons, coasters, trucks, containers and oil tankers are passed and a data member that hold the total amount of money. Finally design the member functions that will perform the function of counting and totaling of money. Cars, coasters, wagons =100 Containers, trucks, oil tankers =200 in one day total number of cars …………………………... coasters …………………………… wagons …………………………… containers …………………………… trucks …………………………… oil tankers Total amount of cars ……………..coasters ……………..wagons ……………..containers …………….. trucks ………………oil tankers

4.2

Problem No.2

Design a class that holds the data member to record the input in the form of 7/9 from the user and output is also in the same form. Design the member functions that will add the two fractions and also subtract the two fractions. Write a main program that allows the use to input the two fractions repeatedly and then display their sum and difference. Hints: For Addition:

a / b + c / d = (a*d + b*c) / (b*d) a / b - c / d = (a*d – b*c) / (b*d) Calculate the fowling 7/9 + 6/5 = 3/5 + 7/2 = Objects 1st object as function 2nd object as argument 3rd object as result Or 2 object as argument And one for storage of result

4.3

Problem No.3

class employee { private: char name[30]; long num; public: void get() { cout<<”\n Enter your name: “; cin>>name; cout<<”\n Enter employee number:”; cin>>num; } void show() { cout<<”\n Name is: “<
