Title: A date writer simple...

Shonoby - December 30, 2006 09:22 AM (GMT)

Well, i was bored like i always am so i decided to write this code just to see if i could with 'class', and yes it worked i made 2 versions one at 'randome' and the other a 'user input'
public: void printsetUP() is also univerisal time, its needed so printDate knows if it is PM or AM, hences printsetUP
Here is the randome one:

CODE

// Times In a Day
// By: Darwin Aguirre
#include <iostream>

using std::cout;
using std::endl;

#include <iomanip>

using std::setfill;
using std::setw;

#include <cstdlib>
#include <ctime>

class Time {

public:
Time();
void setTime( int, int, int, int );
void printsetUp();
void printDate();

private:
int month;
int day;
int hour;
int minute;

};

Time::Time()
{
month = day = 1;
hour = minute = 0;
}

void Time::setTime( int m1, int d, int h, int m2 )
{
month = ( m1 >= 0 && m1 <= 12 ) ? m1 : 0;
day = ( d >= 1 && d <= 31 ) ? d : 0;
hour = ( h >= 0 && h < 24 ) ? h : 0;
minute = ( m2 >= 0 && m2 < 60 ) ? m2 : 0;
}

void Time::printsetUp()
{
cout << setfill( '0' ) << setw( 2 ) << hour << ":"
<< setw( 2 ) << minute;
}

void Time::printDate()
{
const char *month1[ 13 ] =
{ "WONT HAPPEN", "January", "Febuary", "March", "April", "May", "June", "July", "August",
"September", "October", "December" };

cout << "On " << month1[month] << '/' << day << "/92 at ";
cout << ( ( hour == 0 || hour == 12 ) ? 12 : hour % 12 )
<< ":" << setfill( '0' ) << setw( 2 ) << minute
<< ( hour < 12 ? " AM" : " PM" ) << endl;
}

int main()
{
Time T;
srand( time( 0 ) );
int m1;
int d;
int h;
int m2;

cout << "Base time without change is: ";
T.printDate();

cout << "Base time changed to my birthday is: ";
T.setTime( 8, 16, 19, 20 );
T.printDate();

cout << "Base time changed to randome is: ";

m1 = ( 1 + rand() % 11 );
d = ( 1 + rand() % 30 );
h = ( rand() % 23 );
m2 = ( rand() % 59 );

T.setTime( m1, d, h, m2 );
T.printDate();

return 0;
}

Heres the one with user input:

CODE

// Times In a Day, User Input
// By: Darwin Aguirre
#include <iostream>

using std::cout;
using std::cin;
using std::endl;

#include <iomanip>

using std::setfill;
using std::setw;

class Time {

public:
Time();
void setTime( int, int, int, int );
void printsetUp();
void printDate();

private:
int month;
int day;
int hour;
int minute;

};

Time::Time()
{
month = day = 1;
hour = minute = 0;
}

void Time::setTime( int m1, int d, int h, int m2 )
{
month = ( m1 >= 1 && m1 <= 12 ) ? m1 : 0;
day = ( d >= 1 && d <= 31 ) ? d : 0;
hour = ( h >= 0 && h < 24 ) ? h : 0;
minute = ( m2 >= 0 && m2 < 60 ) ? m2 : 0;
}

void Time::printsetUp()
{
cout << setfill( '0' ) << setw( 2 ) << hour << ":"
<< setw( 2 ) << minute;
}

void Time::printDate()
{
const char *month1[ 13 ] =
{ "WONT HAPPEN", "January", "Febuary", "March", "April", "May", "June", "July", "August",
"September", "October", "December" };

cout << "On " << month1[month] << '/' << day << "/92 at ";
cout << ( ( hour == 0 || hour == 12 ) ? 12 : hour % 12 )
<< ":" << setfill( '0' ) << setw( 2 ) << minute
<< ( hour < 12 ? " AM" : " PM" ) << endl;
}

int main()
{
Time T;
int m1;
int d;
int h;
int m2;

cout << "Base time without change is: ";
T.printDate();

cout << "Base time changed to my birthday is: ";
T.setTime( 8, 16, 19, 20 );
T.printDate();

cout << "\nNow Enter Your Time\n";

cout << "Enter month( number according to month ): ";
cin >> m1;
cout << "Enter day: ";
cin >> d;
cout << "Enter hour: ";
cin >> h;
cout << "Enter minute: ";
cin >> m2;

cout << "Base time changed to your settings are: ";
T.setTime( m1, d, h, m2 );
T.printDate();

return 0;
}

Thats about it... Both are simple, not hard at at only a couple of diffences
If you want to get PM in the user input u have to use unversial time like this:
if i want to get 9:20 PM i will do this:
21 for hour
20 for min ( minutes are the same universial and standared )
Universial is decribed as such:
0 hr ( this is the same for unviersial && standared time, up till 12)
1 hr
2 hr
3 hr
4 hr
5 hr
6 hr
7 hr
8 hr
9 hr
10 hr
11 hr
12 hr (AM)

13 hr ( 1 PM )
14 hr ( 2 PM )
15 hr ( 3 PM and so on )
16 hr
17 hr
18 hr
19 hr
20 hr
21 hr
22 hr
23 hr

This is universial time....
K hope u like it!
