简单枚举(用k来记录经过的天数)

#include<bits/stdc++.h>
using namespace std;
bool is_ren(int n)
{
	if(n % 400 == 0 || (n % 4 == 0 && n % 100 != 0))return true;
	return false;
}
int m[13] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
int main()
{
	int y = 2000;
	if(is_ren(y))m[2] = 29;
	int k = 0, flag = 0;
	for(int i = 1; i <= 5; i ++)
	{
		for(int j = 1; j <= m[i]; j ++)
		{
			k ++;
			if(i == 5 && j == 4)
			{
				cout << k;
				flag = 1;
				break;
			}
		}
		if(flag)break;
	}
	return 0;
