Objective

The objective of this assignment is:

 

  • To give you the idea of practical implementation of class with attributes and functions

 

For any query about the assignment, contact at CS304@vu.edu.pk

 

GOOD LUCK

Problem Statement:

 

Consider the following attributes and functions of the class Time:

Attributes:

  • int hour
  • int minute
  • int seconds

Functions:

  • void setTime(int, int, int);
  • void show12Hour();
  • void show24Hour();

 

Write a program to instantiate the object of a class Time from the main() function and constructor is called of the class Time automatically to initialize the private data members of the class with 0. Time is printed on the screen in 12 hours format and 24 hours format as follows:

 

Initial Time:

 

Time display in 12 hours format: 12:00:00 AM

Time display in 24 hours format:  00:00

 

After that use the setTime() function to set the time  by passing the 3 attributes of time i.e setTime(13,55,23) and show the time again after setting:

 

After set:

 

Time display in 12 hours format: 01:55:23 PM

Time display in 24 hours format: 13:55

 

Now try to use setTime() function for setting invalid values i.e setTime(25,67,98) . Your program should not set invalid values of time and show finally the time as initial.

 

Time display in 12 hours format: 12:00:00 AM

Time display in 24 hours format: 00:00

friends dont wory its easy start discussion !

WOW!

Very easy assignments, students should have to hear the lectures and follow the handouts, after that download the instructions from your LMS download section and follow the instructions. I hope you will be able to solve your assignments. If you still have any query please post here, I will try to solve your queries.

To install software you can ask for me Teamviewer session.

Note: Do not copy past any material from here, just get idea from here and implement it. Other wise you will get zero marks.

Thanks!

#include <iostream>

using name space std;

class Time 

{

private :int hour;

int minute;

int seconds;

publice:

void setTime(int, int, int);

void show12Hour();

void show24Hour();

};

here is the idea and algo to solve the problem,, please read and study and understand as much as you can,, copying without learning is wastage of time,,, enjoyyy
