windows XP SP3，VC6.0.

代码如下：
#include <iostream.h>

#define N 8
static char q[N][N];
static int a[N];
static int b[2N-1];
static int c[2N-1];
int s,t;
for(s=0; s <N; s++){
    a[s] = 0;
    for(t = 0; t <N; t++)
        q[s][t] = ’*’;
}
for(s=0; s <2N-1; s++){
    b[s]=c[s]=0;
}
void queen(int n){
    for(int i=n; i>=0; i--){
        if(a==0 && b[N-n+i-1]==0 &&c[n+i-1]==0){
            q[n] = ’Q’;
            a = 1;
            b[N-n+i-1] = 1;
            c[n+i-1] = 1;

            if(n-1>=0){
                queen(n-1);
            }else{
                for(s=0;s <N;s++){
                    for(t=0;t <N;t++)
                        cout < <q[s][t] < <’ ’;
                    cout < <’\n’;
                }
                cout < <’\n’;
            }
            q[n] = ’*’;
            a = 0;
            b[N-n+i-1] = 0;
            c[n+i-1] = 0;
        }
    }
}
错误如下： Compiling...

2N应该是2*N，自己改了过来了，但是还是有错，
