PROBLEM:
Add to the time class of Exercise 5 the ability to subtract two time values using theoverloaded (-) operator, and to multiply a time value by a number of type float, usingthe overloaded (*) operator.
PROGRM:
#include "stdafx.h"
#include "iostream"
using namespace std;
/////////////////////////////////////////////////////////////////////////////////////////
class time
{
private:
inthrs, mints, secs;
public:
time( ) :hrs(0), mints(0), secs(0)
{ /*Empty Body*/ }
time(int h, int m, int s):hrs(h), mints(m), secs(s)
{ /*Empty Body*/ }
void display( ) const
{
cout<<hrs<< ":" << mints << ":" <<secs<<endl;
}
time operator - (time) const;
time operator * (float) const;
};
//---------------------------------------------------------------------------------------
time time::operator - (time t2) const
{
inthr, min, sec;
if(hrs>= t2.hrs)
hr = hrs - t2.hrs;
else
hr = t2.hrs - hrs;
if(mints >= t2.mints)
min = mints - t2.mints;
else
min = t2.mints - mints;
if(min > 59)
{
min -=60;
hr++;
}
if(secs>= t2.secs)
sec = secs - t2.secs;
else
sec = t2.secs - secs;
if(sec > 59)
{
sec -=60;
min++;
}
return time(hr, min, sec);
}
time time::operator * (float num) const
{
inthr=hrs, min=mints, sec;
sec=secs*num;
if(sec > 59)
{
sec -=60;
min++;
}
if(min > 59)
{
min -=60;
hr++;
}
return time(hr, min, sec);
}
/////////////////////////////////////////////////////////////////////////////////////////
void main( )
{
const time time1(10,25,2), time2(5,59,59);
time time3,time4;
cout<< "Time1 is: ";
time1.display( );
cout<< "Time2 is: ";
time2.display( );
time3 = time1 - time2;
cout<< "Time3 is: ";
time3.display( );
time4 = time1 * 32.14;
cout<< "Time4 is = Time1*32.14 = ";
time4.display( );
system("pause");
}
OUTPUT:
