Program to check if given strings form an acrostic

/* program to check if given strings form an acrostic */

Write a program that checks if given set of strings form an acrostic. The set of strings is said to form an acrostic when
the strings read in any direction come in same order. For example,

ROTAS
OPERA
TENET
AREPO
SATOR

the above strings if read horizonatally from left to right and right to left, or vertically from top to bottom and from bottom to top come in same order.

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

#define MAX1 5
#define MAX2 6

void main( )
{
char str[MAX1][MAX2] ;
int i ;
int check ( char * ) ;

clrscr( ) ;

strcpy ( str[0], "ROTAS" ) ;
strcpy ( str[1], "OPERA" ) ;
strcpy ( str[2], "TENET" ) ;
strcpy ( str[3], "AREPO" ) ;
strcpy ( str[4], "SATOR" ) ;

printf ( "\nThe strings are:\n" ) ;
for ( i = 0 ; i < MAX1 ; i++ )
printf ( "%s\n", str[i] ) ;

i = check ( str[0] ) ;

if ( i == 1 )
printf ( "The given strings form an acrostic\n" ) ;
else
printf ( "The given strings do not form an acrostic\n" ) ;

getch( ) ;
}

/* checks if forms an acrostic */
int check ( char *s )
{
int i, j ;
j = ( MAX1 * MAX2 ) - 2 ;

for ( i = 0 ; i < 15 ; i++, j-- )
{
if ( * ( s + i ) == * ( s + j ) )
continue ;
else
break ;
}

if ( i == 15 )
return 1 ;
else
return 0 ;
