scan.cpp

次界面好用但是也可能有许多不足还希望有贤人志士指点迷津！

#include"traffic.h"
step Scan(ALGraph G)
 {
   char c = '0';
   while(c == '0')
   {
   openfile("scan");
   c = NEXTSTEP;
   switch(c)
    {
      case '1':
      c = Scanall(G);break;
      case '2':
      c = Scandes(G);break;
      case '3':
      c = Scanstart(G);break;
      case 'e':case 'i':case 'q':
      break;
      default:c = '0';
    }
  }
  return c;
 }
