One day when I was little, I had to write a cycle, but I did not know how to do it, and I did not have internet. So I tried to find a solution in the book. I only had a Delphi book (Pascal). And I found the piece of code that suits me:

begin
    repeat
        Sum := Sum + start;
        start := start + 1;
    until(start>=finish);
end;

And put it in the code. But it does not work. I found out that instead of := on C++ you need to put =. And I replaced it, but it still did not work. Could you help me to adapt the code to C++. But I have one condition: You can not change the code that is written in Pascal. In the test, the code should also work.
