Hello! Why I got WA?
I can't understand :| IMO this must work... Tnx all.
----------------------------------------------------
dayTotal = (LastDay - FirstDay) + 1;
   for(counter = 1; counter <= dayTotal; counter++)
      {
    n = counter % 2;
    if(n != 0)
       fuse++;
    }
-----------------------------------------------------

#include <iostream>

int main()
{
    int a,b;
    int answer=0;
    std::cin>>a>>b;
    if(a%2==0)a++;
    for(int i=a;i<=b;i+=2)
        answer++;
    std::cout<<answer;
    return 0;
}
