Yeah, i'm aware of the Yucca Mountain project. It's in my practically in my backyard, i live in Las Vegas. I think it's worth mentioning that the initial moisture tests that they ran to assure that Yucca Mountain is a dry enough environment to safely store the waste (seeing as any amount of moisture could lead to run off, and therefore possible contamination of surrounding areas and water supplies), were "inconclusive". Why? because all of their instruments suffered water damage.

I'm looking for soures now.

Don't use a double; it'll end up being a decimal instead of the integer you want. Use a long int instead (ex. long int term3 = 0;).

Otherwise, it looks pretty good. :D

Heh, i know it's silly, but a do..while loop reads more humanely than for loops do to me. Again, i'm sure it's just my inexperience speaking.

anywho, i've got another problem with the second project euler problem. (oy. at this rate, i'll NEVER get all 217 :()
The problem asks for the sum of all the even numbers that are less than 4 million that appear in the Fibonacci sequence. The following is my code.

do
{
term3 = term1 + term2;
if( term1 % 2 == 0 )
{
sum = term1 + sum;
}
else if( term2 % 2 == 0 )
{
sum = term2 + sum;
};
term1 = term2;
term2 = term3;
}while( term3 < 4000000 )

I have a feeling that my integers need to be doubles but when i do that, i get a compile-time error telling me that i cant use a binary operator (%) on double integers...

Try this instead:

for(checking = 1; checking < 1000; ++checking)
{
   if(checking%3==0||checking%5==0)sum=sum+checking;
}

I guess C++/Java doesn't agree with GS.

You have a semicolon after the end bracket of the if statement, which causes the if statement to execute a null command and causes the stuff in the brackets to execute unconditionally.

You're also using a do...while when a for loop would be better, but that doesn't affect functionality. :P

So I'm pretty new to C++, and I'm in need of a little help trying to understand the way my code is being interpreted. I'm not completely clueless, as I've read a few texts at decent length; but my problem is that i've got very little experience in application. I've successfully programmed simple things like a program to change pennies into dollars, quarters, nickels, and dimes.

Anyhow, I read about this Project Euler thing and I thought it was a perfect chance for me to get some practice. But I've failed on the very first problem many times already, and i've approached the problem in many ways, yet nothing i do seems to work. Anyone else fluent in C++ that can point out where I've screwed up?

The problem asks for the sum of all the multiples of 3 and 5 that are less than 1000. The following is my code.

do{
checking++;
     if( (checking % 3) == 0 || (checking % 5) == 0 );
          {
               sum = sum + checking;
          };
    }while(checking < 999);

Glitchspot is not agreeing with me today :(
