Question

我有一个包含埃尔维斯普雷斯利作品唱片的文件。我需要将它输入到我的程序中，同时将：歌曲名称，发行日期，专辑名称以及分钟和秒钟分成不同的变量。我不是很多，而且我确定它充满了错误（Haven已编译）但我真的会对此有所帮助。非常感谢你提前。这就是我得到的。

编辑：我只是需要帮助输入而不是计划的其余部分

到目前为止我对这个计划的看法。

#include <iostream>
#include <iomanip>

using namespace std;

int main(){

 char songName[256];

 String AlbumName[5];
 String ReleaseDate[5];
 String SongName[5][14];\
 int hours[5];
 int minutes[5][14];
 int seconds[5][14];

 for(int i = 0; i < 5; i++){
  getline(cin,AlbumName[i]);
  getline(cin,RelaseDate[i]);
  for(int r = 0; r < 14; r++){
   cin.get(SongName[i][r], 41);
   cin.get(minutes[i][r], 42);
   cin.get(seconds[i][r], 44);
  }

 }
}

在得到第一个答案之后，我得到了一堆错误，我可以看到它是如何工作的，但它又不是。

#include <iostream>
#include <iomanip>
//#include <fstream>

using namespace std;

 struct Album
    {
      string albumName;
      string releaseDate;
      string songName;
      int minutes;
      int seconds;
      //..... other members
    };

    int main()
    {
        struct Album albums[5][14];
        // do other things
        for (int i=0; i< 5;i++){
         /// read in values like albums[i].albumName = value ...
         cin.get(albums[i][0].albumName, 22);
         cin.get(albums[i][0].releaseDate, 22);
         for(int r=0; r< 14;r++){
            char a;
            cin >> a;
            if(a == '='){
                r == 14;
            }
            get(albums[i][r].songName, 39);
            cin >> albums[i][r].minutes >> albums[i][r].seconds;
            // cin >> albums[i][r].songName >> albums[i][r].minutes >> albums[i][r].seconds;
           }
        }


        for(int i = 0; i<5;i++){
                cout<<albums[i][0].albumName<<endl<<albums[i][0].releaseDate<<endl;
                for(int r = 0; r<14;r++){
                        cout <<albums[i][r].albumName <<"       "<< albums[i][r].minutes <<" "<< albums[i][r].seconds;
                }
        }
        return 0;
    }

Answer 1

您应该使用结构（可能名为＆＃39;相册＆＃39;）来保存特定相册的所有相关数据，如专辑名称，发布日期等。然后创建一个结构数组，从文件中读取数据值并存储在结构中。

    struct Album
    {
      string albumName;
      string releaseDate;
      //..... other members
    };

    int main()
    {
        struct Album albums[5];
        // do other things
        for (int i=0; i< 5;i++){
         /// read in values like albums[i].albumName = value ...
        }
        return 0;
    }

如何输入某个文件，同时将某些部分分配到不同的变量中
