Question

error C2100: illegalindirection

#include<iostream>
using namespace std;
int main()
{
int a[3][4]={{1,2,3,4},{5,6,7,8},{9,10,11,12}};
int i,j,*p;
p=a;
for (i=0;i<3;i++)
{
for (j=0;j<4;j++)
cout<<*(*(p+i)+j);
cout<<endl;
}
return 0;
}

结果是C:\Program Files\Microsoft Visual Studio\MyProjects\klx\d11.cpp(11) : error C2100: illegal indirection
哪里错了?

Answer 1

已改，看注释

#include<iostream>
using namespace std;
int main()
{
    int a[3][4]={{1,2,3,4},{5,6,7,8},{9,10,11,12}};
    int i,j,(*p)[4];  // p应该是一个指向数组的指针
    p=a;
    for (i=0;i<3;i++)
    {
        for (j=0;j<4;j++)
            cout<<*(*(p+i)+j);
        cout<<endl;
    }
    return 0;
}
