C++中如何访问多维数组
在C/C++语言中，如果想返回一个多维数组的指针，则使用如下的方法:
#include <iostream>
using namespace std;
typedef struct {
int a;
int b;
} BASE;
class Test {
BASE* base[2][2];
BASE base2[10];
public:
Test() {
base2[0].a = 1;
base2[1].a = 2;
base2[2].a = 3;
base2[3].a = 4;
base[0][0] = &base2[0];
base[0][1] = &base2[1];
base[1][0] = &base2[2];
base[1][1] = &base2[3];
}
BASE* (&GetBase())[2][2] {
return base;
}
};
int main()
{
Test t;
BASE* (&a)[2][2] = t.GetBase();
cout << a[0][0]->a << "," ;
cout << a[0][1]->a << "," ;
cout << a[1][0]->a << "," ;
cout << a[1][1]->a << "," ;
return 0;
}
