new and delete
int **a;
a=new int*[3];
for(int i=0;i<3;i++)
a[i]=new int[3];
for(int i=0;i<3;i++)
delete[]a[i];
delete[]a;
or replace line 6 with:
int(*a)[3] = nullptr;
a = new int[3][3];
It's not as hard as you think.
#includeif(min>a[i]) min=a[i];
}
cout << "和为" << sum << endl;
cout << "最大值为" << max << endl;
cout << "最小值为" << min;
}
这家伙很懒，什么都没留下...
