Hexadecimal number Addition

#include <stdio.h>intMain () {__int64 A, B; //because the defined number has a maximum length of 16 bits, it is defined as int64     while(SCANF ("%i64x%i64x", &a,&b)! =EOF) printf (a+b>=0?"%i64x\n":"-%i64x\n",a+b>0? a+b:-a-b);//It is the perfect application of the three-mesh operator to examine the output format of the problem.     return 0;}
