  例如：

  #include<stdio.h>

  int main()

  {    

      int a=1;
  

      while(a!=0)
  

      {

          print("---------菜单--------\n");
  

          printf("--------选项1--------\n");
  

          printf("--------选项2--------\n");
  

          printf("--------选项3--------\n');
  

          printf("--------结束--------\n");
  

          scanf("%d",&a);
  

          switch(a)
  

          {

          case 1:
  

                      printf("执行选项1的操作");
  

                      break ;
  

          case 2:
  

                       printf("执行选项2的操作");

                      break ;

          case 3;
  

                       printf("执行选项3的操作");

                      break ;

          case 0:
  

                       printf("结束选择");

                      break ;

          default:

                       printf("输入有错");
  

                      break ;

          }
  

      }

          eturn 0;
  

      }
