下列程序段的执行结果是( )。
Dim A(3,3)
For M=1 To 3
For N=1 To 3
If N=M Or N=3-M+1 Then
A(M,N)=1
Else
A(N,N)=0
End If
Next N
Next M
For M=1 To 3
For N=1 To 3
Print A(M,N)
Next N
Next M
A.1 0 0 0 1 0 0 0 1

第1题:
A)(仕兰微面试题目)
#i nclude
void testf(int*p)
{
*p+=1;
}
main()
{
int *n,m[2];
n=m;
m[0]=1;
m[1]=8;
testf(n);
printf("Data v alue is %d ",*n);
}
------------------------------
B)
#i nclude
void testf(int**p)
{
*p+=1;
}
main()
{int *n,m[2];
n=m;
m[0]=1;
m[1]=8;
testf(&n);
printf(Data v alue is %d",*n);
}
下面的结果是程序A还是程序B的?
Data v alue is 8
那么另一段程序的结果是什么?
