没啥难度的模拟题，按规则写就是了

#include<iostream>#include<map>#include<cstring>#include<cctype>#include<cstdio>using namespace std;int main(){string S[] = { "A", "A#", "B", "C", "C#", "D", "D#", "E", "F", "F#", "G","G#" };map<string, int> M;for (int i = 0; i < 12; i++)M[S[i]] = i;M["Bb"] = 1;M["Db"] = 4;M["Eb"] = 6;M["Gb"] = 9;M["Ab"] = 11;bool flag[12];string s[3], temp;while (cin >> s[0] >> s[1] >> s[2]){memset(flag, 0, sizeof(flag));for (int i = 0; i < 3; i++){temp = s[i];if (islower(s[i][0]))temp[0] = temp[0] - 'a' + 'A';flag[M[temp]] = true;}bool major = false, minor = false;int i;for (i = 0; i < 12; i++)if (flag[i]){int mid1 = (i + 4) % 12;int mid2 = (i + 3) % 12;int end = (i + 7) % 12;if (flag[mid1] && flag[end]){major = true;break;}if (flag[mid2] && flag[end]){minor = true;break;}}if (major)printf("%s %s %s is a %s Major chord.\n", s[0].c_str(),s[1].c_str(), s[2].c_str(), S[i].c_str());else if (minor)printf("%s %s %s is a %s Minor chord.\n", s[0].c_str(),s[1].c_str(), s[2].c_str(), S[i].c_str());elseprintf("%s %s %s is unrecognized.\n", s[0].c_str(), s[1].c_str(),s[2].c_str());}return 0;}
