数组循环移位出现不确定的值

[simon_夏]

#include <iostream>
#include <vector>

using namespace std;

int main()
{	
	int n,T,m,place,temp;
	size_t i,j,k = 0;

	cout << "input the number of people( 0<=n<=20 ) and number of group(T)" << endl;
	while ((cin >> n >> T) && (n < 0 || n > 20))
	{
		cout << " 0<=n<=20" << endl;
	}
	int peo[n-1],peonew[T-1][n-1];
	vector<int> mm;
	for (j = 0;j != n; ++j)
		peo[j] = j + 1;

	for (j = 0;j != n; ++j)
		cout << peo[j] << " " ;

	cout << endl;

	cout << "input " << T << " groups of m( 0<=m<=100) " << endl;
    for (i =0; i != T; ++i)
	{
		cin >> m;
		mm.push_back(m);
	}
	vector<int>::size_type ix = 0;
	for (i = 0;i != T; ++i )
	{
		place = mm[ix] % n;
		++ix;
		for (j = (n - place); j != n; ++j,++k)
		{
			temp =  peo[j];
			peonew[i][k] = temp;
		}
		for (j = 0,k = place; j != n - place; ++j,++k)
		{
			temp = peo[j];
			peonew[i][k] = temp;
		}
		
			
	}
	for (i = 0;i != T; ++i)
	{	
		for (j =0;j != n; ++j)
			cout << peonew[i][j] << " ";
		cout << endl;
	}
	cout << endl;		


	return 0;
}

运行结果如下：
input the number of people( 0<=n<=20 ) and number of group(T)
20 8
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
input 8 groups of m( 0<=m<=100)
1 2 3 4 5 6 7 8

20 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
19 -1081969020 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

13 14 15 16 17 18 19 1 2 3 4 5 6 7 8 9 10 11 12 13

其中第2，7，8组出现错误

求问各位大神

我改了一个地方：

for (j = (n - place), k = 0; j != n; ++j,++k)

你的：

for (j = (n - place); j != n; ++j,++k)

照你的测试数据，我用　２０　４，都正常，２０，５以上，最后一行出错，开头对，后面全是２０，一时想不到什么问题！

你试试看，看看你的是怎样，有问题再联系，我其实不懂向量，猜的。

一定是数组越界了，仔细检查下

楼主什么编译器？
