no solution here your code didn't work either. although much better. I seem to start with some sort of structure but I end up hacking it to make it fit, making it less user friendly.

What about the lack of a newline after printing sum
Code:

`cout << sum;`
Try
Code:

`cout << sum << endl;`

nope that didn't work either.

Here's a link to the C++ problem: Sum of Naturals divisible by 3 and 5 | Programr It only has an 11.5% success rate.

Here's another "easy" one with a low success rate (6%).
Sum of Odd Numbers | Programr
Sum all odd numbers less than or equal to a given maximum.
E.g., Given 10 the answer is 25 because 1 + 3 + 5 + 7 + 9 = 25. Given 15 the answer is 64 because 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64

The code below fails.
Code:

```#include <iostream> #include <string> using namespace std; int main(int argc, char* argv[]) {     long max = 0;              //GIVEN     long sum = 0;              //GIVEN     cout<<"Enter Maximum No:";  //GIVEN     cin>>max;                  //GIVEN     for(long i=1;i<=max;i+=2)         sum += i;     cout<<"Sum of Odd no. is:"; //GIVEN     cout<<sum<<endl; }```
You should report these problems. It's possible it's due to capitalization differences or something idiotic like that.

Hmm, shame that seems a bit discouraging I was enjoying the site. I sent some feedback to them and will advise if I hear anything. Thanks for the help, at least their wasn't any obvious issues with my code.

Okay, no reply from the website but I found the solution to sum of odd numbers + sum of naturals + others. It was very idiotic.
Remove the last line of code that they give you so that you only output the answer. so in oogabooga example. Just remove line 13.
