Hey folks,
Got an exam tomorrow and need these done in C++ in a short time. They're very easy exercises and I'm just too busy with my websites and other projects :). I'd be glad to reward the one who'll finish these for me with a domain ;) (www.thetechtalks.com)...
I need those finished in 2 hours:

Thanks
Welcome to the board. Please read our homework policy. In other words, write some code and post whatever questions you have here, if you get stuck. ;)
Cheers.
What a load of rubbish - pathetic excuse.
Even for a beginner, this is only a couple of hours work I would imagine! It's pretty much all the same code. You'd better get some caffeine in!
Im offering a domain in exchange for this...Quote:

Perhaps something like this would be more appropriate, then? Point is, this just isn't the forum for such a thing. Good luck.
Someone should just write the ugliest code they can imagine, that still fulfill those extremely simple criteria.:devil:
Ok Ive started to do those on my own...
I dont understand the second one at all: Write a program to calculate the sum of N numbers.
Can anybody explain what does that mean?
'N numbers' means any given number.Quote:

Here's the first one. I'll be expecting my domain in two hours.
Code:#include <iostream>
using
namespace
std
;
int
main
(
){int
x =
0
,
n
=
51
;
for (
int
i =
0
/*Carefully note this section*/
; i <
n ; ++
i
) {
cout <<
i
<< endl ;
}
return 0;
}
I think that's it, thanks.Quote:

Looking at his assignment he is required to use loops, but yes Gauss's equation would be simpler!Quote:

system ("pause");
return 0;
}
OK take a look at this:
Write a program that calculates the sum of squares of numbers from 1 to N.
Heres what Ive done but the result (when i run) its not correct.
Code:#include <iostream>
//Write a program that calculates the sum of squares of numbers from 1 to N.
using namespace std;
int main()
{
int N = 0;
int sum = 0;
cout << "Enter a number...>" << endl;
cin >> N;
for( int i = 1; i <= N; i = i + 1){
sum = sum*sum + i;
}
cout << "The total sum of of squares of numbers from 1 to N is: " << sum << endl;
system ("pause");
return 0;
}
Instead of multiplying the 'sum' with itself and then adding 'i', you should be adding the product of 'i' with itself to 'sum'.Quote:

Ok thanks I fixed that and its working :). THanks a lot.Quote:

Write a program that calculates an average of n scores entered by user (dont understand it)
Write a program to create a countdown from N to 1 and display a text as a fire (need some serious help on this)
1) Set up a loop as you did in your previous problems. Apply the modulo operator to the increment variable. If it's zero, then X divides it evenly, so print it.Quote:

Each iteration, add it to the running total, and increment a counter that keeps track of the number of entries thus far (alternately, you can prompt the user for the number of scores to be entered, beforehand, but this is a bit less flexible). After the data entry phase is complete, divide the running total by the number of entries to obtain the average.
3) Not clear on the meaning of that one.
Thanks all of you.
Finished.
Right, so you were publicly offering a bribe for others to help you break the rules?Quote:
