请问大大有谁会用goto loop 吗？

我朋友的code需要用到。（虽然很冒险）

他的code:

不明白为什么要用到goto，无论如何， syntax 如下

#include <iostream>
using namespace std;
int main()
{
int input;
cout << "goto : ";
cin >> input;
switch(input)
{
case 1:
goto ab;
case 2:
goto ac;
case 3:
goto ad;
case 4:
goto af;
}
ab:
cout << "ab" << endl;
ac:
cout << "ac" << endl;
ad:
cout << "ad" << endl;
af:
cout << "af" << endl;
return 0;
}

我的朋友想让user key-in 'y' 之后，回去前面再run过，有想过要用do-while loop, 可是因为前面已经用了do-while loop，两个do-while loop 混淆了

我的问题：

我现在的program是当其中一个player打'Q'的时候，整个program就停了，所以我想改成就算某某player quit 了，其他的player还是可以continue玩下去。

想过放do-while，可是因为之前已经有一个do-while了，所以行不通。。。
有什么建议吗?

另一个无礼取闹的error:

for (int x=0; x<n; x++)
{
cout<<"Please enter player "<<(x+1)<<"'s name.\n"; //records players' name
cin.getline (name[x], 100);
}
for (int x=0; x<n; x++)
{
cout<<"Player "<<(x+1)<<"'s name is "<<name[x]<<".\n";
}
for (x=0; x<n; x++) // save players' position into array "player"next = number;
{
next=x+1；
if (next==n+1)
next=0;
cout<<"\n\n\n\n"<<name[next]<<"'s turn!!!\n\n\n\n\n\n";
}

复制代码

括弧那些应该没问题，第一次looping的时候没问题，可是要loop第二次的时候，就会出现
Thread stopped.
Fault: access violation at 0x407c01:write of address 0X18
之前的是
next = x+2;
      if (next==n+1)
            next=1;
            cout<<"\n\n\n\nPlayer "<<next<<"'s turn!!!\n\n\n\n\n\n";

本来没有问题的，value一改问题就来了

谁能帮我看看？

你是不是要说

before

next = x+2;
if (next==n+1)
next=1;

复制代码

after

next = x+1;
if (next==n+1)
next=0;

复制代码

而新的code run不到？？？

差不多是酱啰，之前可以的，换一换value就不行
了。。。。

logic error

n 是多少个玩家, 比如两个
n = 2,

慢慢来分析

for (x=0; x<n; x++) // save players' position into array "player"next = number;
      {
      next=x+1；
            if (next==n+1)
            next=0;
            cout<<"\n\n\n\n"<<name[next]<<"'s turn!!!\n\n\n\n\n\n";
      }
----------------------
n = 2,

x = 0 的时候,
x<n // true 0 < 2

next =  0 + 1 // next == 1

            if (next==n+1) // 1 !=  2 + 1

cout<<"\n\n\n\n"<<name[next]<<"'s turn!!!\n\n\n\n\n\n"; // cout << name[1] ?? 应该是 cout << name[0] 吧

x = 1 的时候
x < n // true 1 < 2

next = 1 + 1 // next

            if (next==n+1) // 2 !=  2 + 1

cout<<"\n\n\n\n"<<name[next]<<"'s turn!!!\n\n\n\n\n\n"; // cout << name[2] ??????? 你只有 name[0] 与 name[1] ,
name[2] 的话当然是memory violation 啊。。。

继续

x = 2,
x < n // false 2 < 2

quit loop，

所以你看，你的
            if (next==n+1)
            next=0;

毫无用处，因为 next 永远不可能 == n + 1 的。

你要的应该是这个.

将

for (x=0; x<n; x++) // save players' position into array "player"next = number;
{
next=x+1；
if (next==n+1)
next=0;
cout<<"\n\n\n\n"<<name[next]<<"'s turn!!!\n\n\n\n\n\n";
}

复制代码

换成

next = x+1;
if (next>=n)
next=0;
cout << "\n\n\n\n" << name[next] << "'s turn!!!\n\n\n\n\n\n\n";
}

小弟新来，请大家多多指教
