int error_leg(int leg_num)

  int checkE;

  if (leg_num <= NUMLEG)
    {
      checkE=2;
      return checkE;
    }
  else
    {
      printf("%d Invalid number of legs(min 1 and max of 10 legs).\n", leg_num);
      checkE=1;
      return checkE;
    }
}   

char error_leg_type(char leg_type)
{
  char A, R, B, C, F, S, M, Y, T, D, O;
  int checkF;
    checkF;
  if ( (leg_type == 'A') || (leg_type == 'R') || (leg_type == 'B') ||(leg_type == 'C') ||(leg_type == 'F') ||(leg_type == 'S') || (leg_type == 'M') ||(leg_type == 'Y') || (leg_type == 'T')|| (leg_type == 'D') || (leg_type == 'O') )
    {
      checkF = 2;
      return checkF;
    }
  else 
    {
      printf("%c Invalid leg type. Please Select from above.\n", leg_type);
      checkF = 1;
      return checkF;
    }
}

由于某种原因，我认为我的leg_num 失去了它的价值，并且没有进入打印循环。我确信我将值分配给了数组，因为我在分配它后打印它以确保。奇怪的是，如果我输入 0，它会打印数组中的第一个值，但不会打印超出 1 的任何值。不确定我是否犯了错误，或者只是我没有看到的东西。 （请原谅凌乱）

尝试删除 for( col = 0; col 上的 ;

去过那里，做到了:-)
