下面是一段C++代码,可以根据梅花易数的年月日时起卦法,生成对应的六十四卦:
```c++
#include <iostream>
#include <string>
#include <vector>
using namespace std;
const vector<string> heavenlyStems = {"甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸"};
const vector<string> earthlyBranches = {"子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥"};
const vector<string> trigrams = {"乾", "坤", "震", "巽", "坎", "离", "艮", "兑"};
int main() {
int year, month, day, hour;
cout << "请输入年月日时(格式为:年 月 日 时):" << endl;
cin >> year >> month >> day >> hour;
int y = (year - 1900) % 60 + 1;
int m = month;
int d = day;
int h = static_cast<int>(hour / 2.0 + 0.5) % 12;
string upperTri = heavenlyStems[y % 10] + earthlyBranches[y % 12];
string middleTri = heavenlyStems[m % 10] + earthlyBranches[m % 12];
string lowerTri = heavenlyStems[d % 10] + earthlyBranches[d % 12];
int upperIndex = (y - 1) % 8;
int middleIndex = (m - 1) % 8;
int lowerIndex = (d - 1) % 8;
string gua = trigrams[upperIndex] + trigrams[middleIndex] + trigrams[lowerIndex];
cout << "卦象为:" << gua << endl;
return 0;
}
```
这段代码的思路是首先根据输入的年月日时,计算出对应的天干地支,然后根据天干地支计算出对应的上、中、下卦,并根据上中下卦的三个爻的变化情况,确定对应的六十四卦。具体实现中使用了梅花易数的年月日时起卦法。最后输出生成的卦象。
