關於測資，是否會有A>B的問題？

程式：

#include<iostream>
using namespace std;
int main()
{    
      int a,b,c,d,e;
      while(cin>>a>>b)
      {
                      d=a%2;
                if(d==0)
                {
                       e=b%2;
                       if(e==0)
                       {
                                c=(b-a)/2+1;
                                cout<<c<<endl;
                       }
                       else
                       {
                           c=(b-a+1)/2;
                           cout<<c<<endl;
                       }
               
                }
                else               
                {
                e=b%2;
                    if(e==0)
                       {
                                c=(b-a)/2+1;
                                cout<<c<<endl;
                       }
                       else
                       {
                           c=(b-a)/2;
                           cout<<c<<endl;
                       }
                   
                }
      }
return 0;
}
