Thread: Returning Array from Function

can any one please explain me this code :-

Code:

#include<stdio.h>
#include<conio.h>

#define ROW 3
#define COL 4

int main()

{
	int i,j;
	int(*c)[ROW][COL];
	int (*fun3())[ROW][COL];
	

	c=fun3();
	printf("Array c[][] in main():\n");
	for(i=0;i<ROW;i++)
	{
	for(j=0;j<COL;j++)
		printf("%d\n",(*c)[i][j]);
	printf("\n");
	}
	_getch();
	return 0;
}

int (*fun3())[ROW][COL]
{
	static int c[ROW][COL]={ 
								6,3,9,1,
								2,1,5,7,
								4,1,1,6

							};

int i,j;
printf("Aray c[][] in fun3():\n");
for(i=0;i<ROW;i++)
{
	for(j=0;j<COL;j++)
	{
		printf("%d",c[i][j]);
	printf("\n");
	}
}
return (int(*)[ROW][COL])c;
}

i am not getting
1.

Code:

int (*fun3())[ROW][COL];

2. working of this :-

Code:

 for(i=0;i<ROW;i++)
	{
	for(j=0;j<COL;j++)
		printf("%d\n",(*c)[i][j]); 

3.

Code:

 return (int(*)[ROW][COL])c;

please explain and suggest some site/blog/book where i can read on this
