ikun真好用

#include <bits/stdc++.h>
#define kun using
#define jinitaimei namespace
#define zhi std
#define kunj int
#define ikun main
#define zhiyin cin
#define nanshenkunkun cout
#define xiaoheizi return
kun jinitaimei zhi;
kunj ikun(){
    kunj a,b;
    zhiyin>>a>>b;
    nanshenkunkun<<a+b;
    xiaoheizi 0;
}
