How to reference **ptr_xx to ptr_yy [xx][xx]

[KevinHall]

This works:

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char* argv[])
{
#if 1
	/***** try out Kevin method ****/
	typedef char char_array_50[50];
	typedef char char_array_500[500];

	char_array_500 *zz = (char_array_500*) malloc(sizeof(char_array_500)*2000); // allocate char[2000][500]
	
	char_array_50 xx[30];
	char_array_50* yy=(char_array_50*)&xx;
#else
	/**** try out sef method ****/

	char (*zz)[500] = (char (*)[500]) malloc(sizeof(char)*500*2000); // allocate char[2000][500]
	
	char xx[30][50];
	char (*yy)[50] = (char (*)[50])&xx;
#endif

	xx[3][5] = 7;
	xx[7][8] = 11;
	printf("A test... The next line should print '7, 11'\n");

	printf("%d, %d\n", yy[3][5], yy[7][8]);

	return 0;
}
