Thread: Returning two-dimensional array in C++

You should be able to return a pointer to an array in a class. Let me work on it for few minutes.

Not very pretty:

Code:

#include <iostream>

typedef int myarray[5][5];

class myclass
{
    myarray arr;

public:
    myclass() {
	for(int i = 0; i < 5; i++)
	{
	    for(int j = 0; j < 5; j++)
		arr[j][i] = i * j;
	}
    }
    friend std::ostream &operator<<(std::ostream &os, const myclass &c);
    myarray * getArray()
	{
	    return &arr;
	}


};

std::ostream &operator<<(std::ostream &os, const myclass &c) 
{
    for(int i = 0; i < 5; i++)
    {
	for(int j = 0; j < 5; j++)
	    os << c.arr[j][i] << " ";
	
	os << std::endl;
    }
    
    return os;
}



int main()
{
    myclass c;
    int (*p)[5][5];
   
    std::cout << c;
  
    p = c.getArray();
    for(int i = 0; i < 5; i++)
    {
	for(int j = 0; j < 5; j++)
	    std::cout << (*p)[j][i] << " ";
	std::cout << std::endl;
    }
    return 0;

}
