十六进制的运算,虽然可以转换成十进制进行运算,但是太麻烦,去搜了一下发现可以直接用%X进行运算,长知识了,不过需要注意的是%X不能输出负数
#include<stdio.h> #include<string.h> #include<math.h> #include<algorithm> using namespace std; int main() { __int64 a,b; while(scanf("%I64X %I64X",&a,&b)!=EOF) { if(a+b<0) { printf("-%I64X\n",-a-b); } else { printf("%I64X\n",a+b); } } return 0; }
