C :

#include<stdio.h>
int main()
{
    int x,y,t,i,s=0;
    scanf("%d\n%d",&x,&y);
    if(x>y)
	{
	   t=x;
	   x=y;
	   y=t;
	}
	for (i=x+1; i<y;i++)
	{
	   if (i%2)
	   {
	   	s+=i;
	   }
	}
	printf("%d",s);
    return 0;	
}

C++ :

#include <iostream>
#include <algorithm>

using namespace std;

int main()
{
    int x,y;

    cin>>x>>y;

    if(x>y) swap(x,y);

    int sum=0;

    int i=x+1;

    while (i<y)
    {
        if ( i%2 ) sum+= i ;

        i++;
    }

    cout << sum << endl;

    return 0;
}
