DESCRIPTION
1.1
Write a program that uses a class.
1.2
Your project will contain files CTime.h, CTime.cpp and TimeApp.cpp.
1.2.1 (Class declaration)
* Place the class declaration and inline functions in a seperate header file, CTime.h.
* Class declaration:
declare CTime as a class
public:
declare a defualt constructor
define an inline destructor with an empty code body
declare getHours as a member function
declare getMinutes as a member function
declare getSeconds as a member function
declare setHours, setMinutes, setSeconds as a member function
declare add as a member function with CTime return and a CTime parameter
private:
declare hours, minutes and seconds as an integer
make the constructor, destructor, get- and set- functions inline.
1.2.2 (Implementation CTime.cpp)
* #include file CTime.h
* place the noninline member function add in a separate file, CTime.cpp
-convert the time values to total seconds before adding them
example:
CTime tm;
long t1Seconds;
t1Seconds = (long)tm.hours*3600 + tm.minutes*60 + tm.seconds;
-add the total seconds together:
t3Seconds = t1Seconds + t2Seconds;
-divide them back out to make the new time hours, minutes and seconds.
- store them in a class CTime variable before returning it.
1.2.3 (member function add)
Module add
Return: CTime
Paramaters: define t2 as a CTime
Data:
define t1Seconds, t2Seconds and t3Seconds as long integers
Processing:
convert hours, minutes and seconds to a long and assign to
t1Seconds
convert t2.hours, t2.minutes and t2.seconds toa long and assign to t2Seconds
SET t3Seconds to t1Seconds + t2Seconds
derive values from t3Seconds to assign to temp.hours, temp.minutes and temp.seconds
return temp
END add
1.2.4 (Application file TimApp.cpp)
this is where the prgoram asks the user for 2 times entered in this format:
12:59:59
the program adds the 2 times and displays the sum
Here's the code I've done:
CTime.h file:
Code:
/******************************* FILE: CTime.h* PROGRAMMER: * DATE: 01/14/09** Declaration of class CTime.*******************************/#ifndef CTime_H#define CTime_H #include <iostream.h> class CTime { public: CTime(); ~CTime() {} int getHours(); int getMinutes(); int getSeconds(); int add(); void setHours(); void setMinutes(); void setSeconds(); private: int hours; int minutes; int seconds; }; inline int CTime::getHours() { return hours; } inline int CTime::getMinutes() { return minutes; } inline int CTime::getSeconds() { return seconds; } inline int CTime::add(CTime) { return CTime } inline void CTime::setHours(int hr) { hours = hr; } inline void CTime::setMinutes(int min) { minutes = min; } inline void CTime::setSeconds(int sec) { seconds = sec; } #endif
Code:
/******************************
* FILE: CTime.cpp
* PROGRAMMER:
* DATE: 01-14-09
*
* Implementation of class CTime.
*******************************/
#include "CTime.h"
#include <iostream>using namespace std;int main(int argc, char *argv[])
{
int t1Seconds;
int t2Seconds;
int t3Seconds;
int CTime::time()
{
t1Seconds = (long)time.hours*3600 + time.minutes*60 + time.seconds;
system("PAUSE");
return EXIT_SUCCESS;
}
