学会用函数strtok，功能：函数返回字符串str1中紧接“标记”的部分的指针, 字符串str2是作为标记的分隔符。如果分隔标记没有找到，函数返回NULL。为了将字符串转换成标记，第一次调用str1 指向作为标记的分隔符。之后所以的调用str1 都应为NULL。

例如:

    char str[] = "now # is the time for all # good men to come to the # aid of their country";

    char delims[] = "#";

    char *result = NULL

   result = strtok( str, delims )

  while( result != NULL ) {

        printf( "result is \"%s\"\n", result );

         result = strtok( NULL, delims );

    }

以上代码的运行结果是：

    result is "now "

    result is " is the time for all "

    result is " good men to come to the "

    result is " aid of their country"

  for(i=0;i<t;i++){
   cout<<a[i];
   if(i==t-1) cout<<endl;
   else cout<<' ';
  }
 }
 return 0;
