c++ - 输入第一个数组出了什么问题？

Question

我是 C++ 的新手，刚刚学会了创建随机数，所以我创建了一个彩票游戏，它有 6 个生成的随机数，范围从 1 到 49，用户会猜到它，但它似乎有问题 [见下面的输出]

.

当我输入第一个数组时，该数组首先在单词 ("Your numbers are: ) 之前输出它

顺便说一句，这是我的代码

 /*int lottoNumbers[6];
  int myLotto[6];
  int ok=1;
  int money=100;
  srand(time(0));
    */
  for (int j=0; j<6; j++)
  {
      int n=1+(rand()%49);
      lottoNumbers[j]=n;
  }
  for (int i=0; i<6; i++)
  {
      for (int j=i+1; j<6; j++)
        {
            if (lottoNumbers[i] == lottoNumbers[j])
            {
                lottoNumbers[j]=(rand()%49+2)/2;
            }
        }
  }
  cout<<"Input your Lucky Numbers: "<<endl;
  for (int j=0; j<6; j++)
  {
      cin>>myLotto[j];
  }
  cout<<endl;
  for (int i=1; i<=6; i++)
  {
      for (int j=i+1; j<=6; j++)
      {
          if (myLotto[i]==myLotto[j])
          {
              ok=2;
          }
      }
  }
  for (int i=1; i<=6; i++)
  {
      if (myLotto[i]>49 || myLotto[i]<1 || ok==2)
      {
          cout<<"\nInappropriate. Lost for lottery";
          ok=0;
          break;
      }
  }
  if (ok==1)
  {
      for (int i=0; i<6; i++)
      {
          if (i==1)
          {
              cout<<"\nYour numbers are: "<<endl;
          }
          if (myLotto[i]<=49 && myLotto[i]>=1)
          {
              cout<<myLotto[i]<<" ";
          }
      }
  }
  cout<<endl;
  cout<<"\nWinning number this time: "<<endl;
  for (int i=0; i<6; i++)
  {
      cout<<lottoNumbers[i]<<" ";
  }
  int nr=0;
  for (int i=1; i<=6; i++)
  {
      for (int j=1; j<=6; j++)
      {
          if (myLotto[i]==lottoNumbers[j])
          {
              nr++;
          }
      }
  }
  cout<<endl;
  cout<<endl;

  int jk=0;

  if (jk==0)
  {
      cout<<"You hit "<<nr<<" numbers."<<endl;
      cout<<"You have "<<(nr*100)/6<<"% chances to win."<<endl;
  }else
  {
      cout<<"You GOT THE JACKPOT";
  }
 /* if (nr==1 || nr==2 )
  {
      money = money + 20;
  }
  if (nr==3)
  {
      money = money + 50;
  }
  if (nr==4)
  {
      money = money + 100;
  }
  if (nr==5)
  {
      money = money + 10000;
  }
  if (nr==6)
  {
      money = money + 100000;
  }
  if (nr==0)
  {
      money= money -10;
  }
  cout<<"Your Money: "<<money<<endl;
*/
  cout<<endl;

有没有办法让它更简单

Answer 1

在你的代码中 i == 1 在打印循环的 second 时间，所以显然 "Your numbers are" 在之后打印第一个数字。我猜你不知何故忘记了你的循环以 i == 0 开始。

这个很简单，改一下就可以了

 if (ok==1)
  {
      for (int i=0; i<6; i++)
      {
          if (i==1)
          {
              cout<<"\nYour numbers are: "<<endl;
          }
          if (myLotto[i]<=49 && myLotto[i]>=1)
          {
              cout<<myLotto[i]<<" ";
          }
      }
  }

对此

 if (ok==1)
  {
      cout<<"\nYour numbers are: "<<endl;
      for (int i=0; i<6; i++)
      {
          if (myLotto[i]<=49 && myLotto[i]>=1)
          {
              cout<<myLotto[i]<<" ";
          }
      }
  }

你在代码中的几个地方犯了类似的错误，例如这个

for (int i=1; i<=6; i++)
  {
      for (int j=i+1; j<=6; j++)
      {
          if (myLotto[i]==myLotto[j])
          {
              ok=2;
          }
      }
  }

应该是这样

for (int i=0; i<6; i++)
  {
      for (int j=i+1; j<6; j++)
      {
          if (myLotto[i]==myLotto[j])
          {
              ok=2;
          }
      }
  }

请记住，C++ 中的数组从零开始，因此您的 for 循环也应该如此。
