代码如下

#include<bits/stdc++.h>
using namespace std;
int m,fm,d,ans,maxd[15]={0,31,28,31,30,31,30,31,31,30,31,30,31};
char c;
int main()
{
	cin>>m>>c>>d;
	if(m>12 || m==0)
	{
		ans++;
		if(m<20 || m%10==0) fm=10;
		else fm=m%10;
	}
	
	if(fm!=0)
	{
		if(d>maxd[fm]) ans++;
	}
	else
	{
		if(d>maxd[m]) ans++;
		else if(d==0) ans++;
	}
	cout<<ans;
	return 0;
}
