[心得]  0.004
判斷奇數 ,照題目說的做就好了

#include <stdio.h>
int main()
{
   int data;
   int a,b,i,sum=0,counter=1;
   scanf("%d",&data);
   while(data)
   {   
       int sum =0;                
       scanf("%d %d",&a,&b);
       for(i=a;i<=b;i++)
       if(i%2==1)
         sum = sum+ i;               
       printf("Case %d: %d\n",counter,sum);                           
       counter++; 
       data--;
                 
   }
   
  system("pause");
  return 0;
}
