思路：

用数组存对应月份的日期

代码：

#include<bits/stdc++.h> using namespace std; #define rpn(i,n) for(int i=1;i<=n;i++) int cal[13]={0,31,0,31,30,31,30,31,31,30,31,30,31}; int main(){ int y,d; cin>>y>>d; if((!(y%4)&&y%100)||!(y%400)) cal[2]=29; else cal[2]=28; int mon=1; rpn(i,12){ if(d>cal[i]){ mon++; d-=cal[i]; }else break; } cout<<mon<<'\n'<<d; return 0; }
