buzz - March 4, 2004 10:51 PM (GMT)

here is a lil program that i made in like 2 min.
its an age finder!

CODE

// age finder
#include <iostream.h>

int main()
{
int a, b;
cout << "Enter year of birth: ";
cin >> a;

b = 2004 - a;
cout << "You are " << b << " or you are going to turn " << b << " this year!";

return 0;
}

I guess we've all made one of these at some point... :lol: Anyway the only thing that's even sorta wrong with it is

CODE

#include <iostream>
using std::cout;
using std:: cin;

Would be better than what you have.

buzz - March 4, 2004 11:05 PM (GMT)

ok ill do that cept il just use

CODE

#include <iostream>
using namespace std;

that should work just fine eh

KTC - March 4, 2004 11:24 PM (GMT)

Yeah.

Sam Fisher vs Solid Snake - March 5, 2004 10:35 PM (GMT)

i agree

buzz - March 5, 2004 10:37 PM (GMT)

thats good u all agree lol

Sam Fisher vs Solid Snake - March 5, 2004 10:52 PM (GMT)

well im glad u thinks so j/k
:wacko:

buzz - March 5, 2004 11:15 PM (GMT)

i have a problem w/ my .EXE file on my age finder. every time i push enter after i enter my birth date, the window closes. isnt ther something i can put into the code to make it pause, like a different library instead of iostream?

KTC - March 6, 2004 12:03 AM (GMT)

Read the bloody FAQ !!!

Sam Fisher vs Solid Snake - March 6, 2004 01:33 AM (GMT)

QUOTE

system("pause");
return 0;

there do that

buzz - March 6, 2004 06:51 AM (GMT)

yup lol i figured that out like an hour after it wasnt workin. at first i thought it was like
#include <conio.h>
_getch();
or something like that
lol thanx newaz

absolute n00b - March 6, 2004 10:36 PM (GMT)

Well here's point from a n00b also:)
I think hard coded stuff is bad, i'm thinkin of that year 2004, that way u'r program won't work next year, so i would like some of the C++ experts to somehow extract system time into aditional variable so this program works allways, next year and everyother year for that matter. I'm i making any sense? :)

something maybe with

#include <ctime>
time (year)

Dunno if i'm making any sense this was just an idea....

Sam Fisher vs Solid Snake - March 6, 2004 11:33 PM (GMT)

in a bit i will sned a post to u explaining time, u wanty current time right? And u want it to constantly update?

Sam Fisher vs Solid Snake - March 6, 2004 11:49 PM (GMT)

CODE

//Clock.cpp
#include <iostream>
#include <ctime>

//main() function
int main()
{
std::time_t now = std::time(0);
std::cout << std::asctime(std::gmtime(&now));

system("pause");
return 0;
}

this takes the current time it loaded on and displays it in gmtime, i will make a better one (that updates) soon

buzz - March 7, 2004 12:18 AM (GMT)

hey good idea!!

absolute n00b - March 7, 2004 12:52 AM (GMT)

Well if i'm not mistaken thats a prog for a GMT time, but what he needs here is current year (extracted in a similar way from the system maybe?)
How to do that?
(even thou it wasn't a bad thing to learn a clock either :)

buzz - March 7, 2004 01:00 AM (GMT)

hey what if you could make the time and once it hits a certain date it changes the code to b = 2005 - a and keeps doing that

absolute n00b - March 7, 2004 01:10 AM (GMT)

Well that is the point of all of this. But i never worked in C++ (just last few days).
So i just know that u must do following in order that to be nice little GuessAge program:
1.) extract year from a sistem somehow (somebody will write this i'm sure, here people RULE!)
2.) store a year into the variable (let's say we called it currentYear)
3.) put variable into your formula
b = currentYear - a

That way year would be allways read from system and would allways be properly updated.
Somebody more expirienced plz act soon!
I hope i'm not mistaken.

Sam Fisher vs Solid Snake - March 7, 2004 01:23 AM (GMT)

edit: oops bad post sry

Sam Fisher vs Solid Snake - March 7, 2004 01:25 AM (GMT)

i didnt quite figure out what u said earlier sry

buzz - March 7, 2004 01:35 AM (GMT)

or we could just do this right

CODE

// age finder
#include <iostream.h>
using namespace std;
int main()
{
int a, b,c;
cout << "Enter current year: ";
cin >> a;
cout << "Enter year of birth: ";
cin >> b;
c = b - a;
cout << "You are " << c << " or you are going to turn " << c << " this year!";

return 0;
}

Sam Fisher vs Solid Snake - March 7, 2004 05:04 PM (GMT)

uh an error in that is iostream.h dont use that since not all comilers understand it, just put <iostream>

absolute n00b - March 7, 2004 06:24 PM (GMT)

OK Snake :)
My question is this: by executing u'r gmt program i get this result:

CODE

Sun Mar 07 18:14:57 2004

That's nice, but i need to extract ONLY year from that (2004 at the end of prog result) and store it into variable currentYear?

Can u show me how to do that?
thx

Sam Fisher vs Solid Snake - March 7, 2004 07:38 PM (GMT)

here it is 12:35 and im going to be gone quite awhile in a few minutes so ill try and make u one when i get back ok, so u just want the year?, no time, no date just year?

absolute n00b - March 7, 2004 09:21 PM (GMT)

Well, in this particular case year is more than enough :)
BUT, if u'r willing i'm ready to learn and listen how to take out all these values separately from gmt time:
Sun Mar 07 18:14:57 2004 (day separately, date, clock, year of course everytihng separately and how to store them into separate variables)
Do u get me? I want to know how to extract any part of the gmt time?
Year for starters.
Thx man.

Sam Fisher vs Solid Snake - March 7, 2004 09:24 PM (GMT)

i will work on it, i would give a week at max to figure it out

this is what i have so far

std::cout << " on ";
today.DisplayAllSeperately();
std::cout << '\a' << std::endl;

system("pause");
return 0;
}

but im getting there, im looking for ways to extract all of it seperatly, i am really close, im thinking of inserting the time/date into the function then display it seperately. ALMOST DONE

KTC - March 7, 2004 10:29 PM (GMT)

emmm guys ... what's the problem with just extracting the year from gmtime() ?

CODE

#include <iostream>
#include <ctime>

int main()
{
time_t rawtime;
tm *ptm;

time( &rawtime );

ptm = gmtime( &rawtime );

std::cout << (ptm->tm_year)+1900 << '\n';

return 0;
}

Sam Fisher vs Solid Snake - March 7, 2004 10:32 PM (GMT)

nothing anyways i figured it out, its a bit longer about 85 lines of code

Here is the console clock finished, the time wont change unless u keep opening it, this was just meant to recieve the time it opened the app, it displays the date too, the only reason it has that
3
7
2004

look is because it shows how to seperate the date and time, it wasnt hard

coool!!!!!

absolute n00b - March 8, 2004 08:18 PM (GMT)

Concidering all that is written here, this is the way i choose:

CODE

#include <iostream>
#include <ctime>
using namespace std;

int main()
{
time_t rawtime;
tm *ptm;
time( &rawtime );
ptm = gmtime( &rawtime );

int currentYear = 0;
currentYear = (ptm->tm_year)+1900;

int a = 0, b = 0;
cout << "Enter year of birth: ";
cin >> a;

b = currentYear - a;
cout << "You are " << b << " or you are going to turn " << b << " this year!" << endl;

return 0;
}

Maybe this way it's a bit more efficient 'cause u don't have to type in years twice and current year is allways updated from the GMT clock.

Sam Fisher vs Solid Snake - March 9, 2004 02:00 PM (GMT)

thats cool, the reson minen is so long is im gonna make a win32 app for it and actually have a clock/date

buzz - March 10, 2004 04:14 AM (GMT)

thats pretty cool cept there is no reason for the time/clock

Sam Fisher vs Solid Snake - March 10, 2004 01:44 PM (GMT)

for u maybe but my app's gonna have both

ih8censorship - March 10, 2004 03:00 PM (GMT)

yeah well mine is gonna be connected to a speaking robot---a GIRL robot ^_^

wait what are we talking about?:lol: ;)

lol an age finder. he wants the time and date.

micster - March 13, 2004 09:34 PM (GMT)

Hi im new here. Earlyer on someone said about executing and it comes on and off. if PAUSE isnt avalible to use then open the exe in a command prompt it wont close it when it finishes

Micster

Days using C= 1

C-Man - March 14, 2004 08:57 AM (GMT)

Type EXIT

micster - March 14, 2004 11:17 AM (GMT)

i know <_<

micster

days using c= 2

FrozenKnight - March 14, 2004 09:28 PM (GMT)

i ws just wondering why we need a program to find something we already know. unless you want to know how many seconds / minutes / hours / days you have lived. i have no need to know how meny years i have lived.
