C 的初级水平，所以问题可能很简单，但就是不知如何解决。
问题我写在程序注释里了。。
#include <stdio.h>
#include <stdlib.h>

struct CD
       {
       char name[20];
       char description[40];
       char category[12];
       float cost;
       int number;
       }/*disc={"Best Hits",
                    "Pop crazy music",
                    "POP MUSIC",
                    24.99, 21
                    }*/
       disc;
main()
      {
      puts("Enter disc information\n\n");
      printf("Enter the name:\n");
      gets(disc.name);
      printf("Enter the description:\n");
      gets(disc.description);
      printf("Enter the category:\n");
      gets(disc.category);
      printf("Enter the price:\n");
      scanf("%f", &disc.cost);
      printf("Enter the location:\n");
      scanf("%d", &disc.number);
     /*问题在于程序运行到这里，就自动关闭，好像我的问题大多是此类的*/
      puts("The information on the CD is:\n\n");
      printf("Name          %s\n", disc.name);
      printf("Description   %s\n", disc.description);
      printf("Category      %s\n", disc.category);
      printf("Price         %.2f\n", disc.cost);
      printf("Location      %d\n", disc.number);
      
      }

#include <stdio.h>

       {

       }/*disc={"Best Hits",

                    "POP MUSIC",
                    24.99, 21
                    }*/
       disc;
main()
      {
      puts("Enter disc information\n\n");
      printf("Enter the name:\n");
      gets(disc.name);
      printf("Enter the description:\n");
      gets(disc.description);
      printf("Enter the category:\n");
      gets(disc.category);
      printf("Enter the price:\n");
      scanf("%f", &disc.cost);
      printf("Enter the location:\n");
      scanf("%d", &disc.number);
     /*问题在于程序运行到这里，就自动关闭，好像我的问题大多是此类的*/
      puts("The information on the CD is:\n");
      printf("Name          %s\n", disc.name);
      printf("Description   %s\n", disc.description);
      printf("Category      %s\n", disc.category);
      printf("Price         %.2f\n", disc.cost);
      printf("Location      %d\n", disc.number); getch();
      
      }

程序最后加一个getch()试试，我已测试可以运行出来

你说大多是此类情况，可能也是缺少那个
