这道题不知道为什么WA,最后换了printf函数输出就AC了。。。醉了

#include
#include
using namespace std;


void prt(double *a,int n)
{
for(int i = 0;i != n - 1;i ++)
{
printf("%.2lf ",a[i]);
}
printf("%.2lf\n",a[n-1]);
}


int main()
{
int n,m;
while(cin >> n >> m)
{
int ** array = new int *[n];


for (int i = 0;i != n;i ++)
{
array[i] = new int [m];
for (int j = 0;j != m;j ++)
{
cin >> array[i][j];
}
}


double * studentave = new double[n];
double * classave = new double[m];
double ave1;


for (int i = 0;i != n;i ++)
{
ave1 = 0;
for (int j = 0;j != m;j ++)
{
ave1 += array[i][j];
}
ave1 = ave1/m;
studentave[i] = ave1;
}


double ave2;
for (int j = 0;j != m;j ++)
{
ave2 = 0;
for (int i = 0;i != n;i ++)
{
ave2 += array[i][j];
}
ave2 = ave2/n;
classave[j] = ave2;
}


int cnt = 0;
int sig;
for(int i = 0;i != n;i ++)
{
sig = true;
for(int j = 0;j != m;j ++)
{
if(array[i][j] < classave[j]) 
{sig = false; break;}
}
if (sig) cnt ++;
}


prt(studentave,n);
prt(classave,m);
cout << cnt << endl << endl;


delete[] studentave;
delete[] classave;
for (int i = 0;i != n;i ++)
{
delete[] array[i];
}
delete[] array;
}


}

以上为WA的代码

#include 
#include 
using namespace std;
void prt(double *a,int n)
{
    for(int i = 0;i != n - 1;i ++)
    {
        printf("%.2lf ",a[i]);
    }
    printf("%.2lf\n",a[n-1]);
}
int main()
{
    int n,m;
    while(cin >> n >> m)
    {
        int ** array = new int *[n];

        for (int i = 0;i != n;i ++)
        {
            array[i] = new int [m];
            for (int j = 0;j != m;j ++)
            {
                cin >> array[i][j];
            }
        }

        double * studentave = new double[n];
        double * classave = new double[m];
        double ave1;

        for (int i = 0;i != n;i ++)
        {
            ave1 = 0;
            for (int j = 0;j != m;j ++)
            {
                ave1 += array[i][j];
            }
            ave1 = ave1/m;
            studentave[i] = ave1;
        }

        double ave2;
        for (int j = 0;j != m;j ++)
        {
            ave2 = 0;
            for (int i = 0;i != n;i ++)
            {
                ave2 += array[i][j];
            }
            ave2 = ave2/n;
            classave[j] = ave2;
        }

        int cnt = 0;
        int sig;
        for(int i = 0;i != n;i ++)
        {
            sig = true;
            for(int j = 0;j != m;j ++)
            {
                if(array[i][j] < classave[j]) 
                    {sig = false; break;}
            }
            if (sig) cnt ++;
        }

        prt(studentave,n);
        prt(classave,m);
        cout << cnt << endl << endl;

        delete[] studentave;
        delete[] classave;
        for (int i = 0;i != n;i ++)
        {
            delete[] array[i];
        }
        delete[] array;
    }

}

以上为AC的代码，不懂为什么cout输出就WA了...
