New Contest C & C++ Welcome

[ILoveVectors]

The following is a link to the pdf containing
the outlines for the contest.


this contest is short and very basic and good for beginners.

because this contest like a two minute coding job
the due date will be Aug 31, 3pm EST.

the following is required by you in doing the coding:

winner will be based on how well the code preforms
and then method used to come about the answer.
no commenting is required, but the code should be
neat and readable.

it will also be judge on its length. (non white space character only)

code can be written in C or C++.

feel free to PM me, or Message me on a messenger
when you are ready to submit your code.

I'm guessing this is using console input and output? (ACM recently changed from console I/O to file I/O)

edit: well if so, my output's a bit different (because there's no standard way to clear the screen), so it looks like this:

10
10      30
6
6       14
7
7       18
11
11      35
15
15      55
16
16      61
100
100     945
10000
10000   942820
1000
1000    29820
21
21      91
22
22      98
0

as you can see, the input is mixed in. if that's alright, use the one I'm submitting now. if not, I'll change it up.

[ILoveVectors]

nope its perfect just liek that and is what i expected

[ILoveVectors]

woot not many replies, but we have the making of a real contest
here, already got 5 submissions!!

do me a favor guys post in here right after you submit,
so the thread get some mroe attention and we get
partitipants!

[noob2c]

Alright, here is my submission

[valis]

I know you told us to submit the files to you, but it's somewhat late over here and I will be at school till past 3 tommorrow (sorry).

My submission:

char GoldCoinCmdLine ( void )
{
	char	cpTmpBuf[255] ;

	DWORD dwTotalDays = 0 ;
	DWORD dwCurrentDays = 0 ;
	DWORD dwCoins = 0 ;
	DWORD dwPay = 1 ;
	DWORD dwTmp = 1 ;

	/* setup element 0 for _cgets */
	cpTmpBuf[0] = 255 ;

	while ( _cgets ( cpTmpBuf ) )
	{
		if ( cpTmpBuf[2] == '0' )
			break ;

		dwTotalDays = atoi ( cpTmpBuf + 2 ) ;
		do
		{
			dwCoins += dwPay ;

			/* have dwPay days elapsed? */
			if ( !--dwTmp )
				dwTmp = ++dwPay ;
		} while ( ++dwCurrentDays < dwTotalDays ) ;

		printf ( "%i %i\n", dwTotalDays, dwCoins ) ;

		/* reset */
		dwCurrentDays = 0 ;
		dwCoins = 0 ;
		dwPay = 1 ;
		dwTmp = 1 ;
	}

	return ( 0 ) ;
}

Compiled under cl shipped with vs.net studio 2003

A "beginner's" contest? Either I'm less than a beginner, or my brain has slowed down tonight. I tried and failed to create such a program. :P

[ILoveVectors]

keep trying id say this is fairly low level, use your brain.

[linkofazeroth]

Like I said, my brain is slow. It's 12 midnight where I am.

Why post the solutions here? Do you guys want enhanced version of your codes to compete with yours? Its unfair for those who submitted early..

[ILoveVectors]

yea my earlier post i didnt exactly mean post
your solutions.

i was looking mroe fo just a post that said you where
in and that you sent yoru submission.

[ILoveVectors]

hey guys ill try and have a winner posted tonight, but
somethign wonderful and unexpeced came up, so
im gonna be out most the day. stay posted though
ill be posting a new contest after i publish the winners.

[ILoveVectors]

i would like to thank everyone who participated, and i hope that
you will continue to compete in my contests.

first off everyone submission was decent, but everyone
contained at least one error or bug, or didnt complete
the assignment to what i expected.

reguardless of that, noob2c and major_smalls
were the last two standing.

major_smalls ends up being the champion here
through the 2nd rule, being number of characters long.

i did not count whitespace or comments, just code
characters.

i will post his code below, if you compile his code you
will notice you will get an error when compiling
due to the "getline" missing the std:: . it was
a obvious error and was easily fixed.

thanks once again, check back in a few i should have another
contest posted.

I do apologize to the others that participated, as for myself, I don't enter contests to compete- I'm just interested in seeing what everyone comes up with and what I come up with myself.

[noob2c]

kudos to major_smalls

here is my code anywho for anyone who wants it as reference

#include <iostream>
#include <vector>

using namespace std;

int main()
{
	int userdays=1,coin=1,total_coins=0,i=0,k=0,temp=0;
	vector<int> user_input,output;
	
	cout <<"Enter the number of days: ";
	while(userdays != 0 )
	{
		cin >> userdays;
		user_input.push_back(userdays);
	}
	
	user_input.pop_back();
	temp = user_input.size();
	for(i = 0; i < temp;i++)
	{
		while(k < user_input[i])
		{
			for(int j = 0; j < coin;j++)
			{
				total_coins += coin;
				k++;
				if(k >= user_input[i])j=coin; //if k is greater than user days, quit loop
			}
			coin++;
		}
		output.push_back(total_coins); //at this point we push the total coins into the vector
		total_coins=0; //reset the values of these vars to original
		k=0;
		coin=1;
	}
	for(int t = 0; t < temp; t++)cout<<"\nNumber of days: "<<user_input[t]<<endl<<"Number of coins at the end of those days: "<<output[t]<<"\n\n";
	return 0;
}
