Answer / raj
Little Endian ->LSB at lower address
Big Endian -> MSB at lower address
e.g:
if the value is 0x0A0B0C0D then
in case of LE storage will be
Address 1000 0D
Address 1001 0C
Address 1002 0B
Address 1003 0A
in case of BE storage will be
Address 1000 0A
Address 1001 0B
Address 1002 0C
Address 1003 0D
Marco to convert(this will convert from LE to BE or BE to
LE--> one for all :) )
#define CON(NUM) (NUM&0x000000FF)<<24|(NUM&0x0000FF00)<<8
|NUM&0x00FF0000)>>8 |(NUM&0xFF000000)>>24

Answer / amit
the endianness of a bus determines whether the MSB is put
into the lowest address
(big-endian) or in the highest address (little-endian).

Small correction in above macro.
'(' was missing in second line.

I need testPalindrome and removeSpace #include <stdio.h> #define SIZE 256 /* function prototype */ /* test if the chars in the range of [left, right] of array is a palindrome */ int testPalindrome( char array[], int left, int right ); /* remove the space in the src array and copy it over to the "copy" array */ /* set the number of chars in the "copy" array to the location that cnt points t */ void removeSpace(char src[], char copy[], int *cnt); int main( void ) { char c; /* temporarily holds keyboard input */ char string[ SIZE ]; /* original string */ char copy[ SIZE ]; /* copy of string without spaces */ int count = 0; /* length of string */ int copyCount; /* length of copy */ printf( "Enter a sentence:\n" ); /* get sentence to test from user */ while ( ( c = getchar() ) != '\n' && count < SIZE ) { string[ count++ ] = c; } /* end while */ string[ count ] = '\0'; /* terminate string */ /* make a copy of string without spaces */ removeSpace(string, copy, ©Count); /* print whether or not the sentence is a palindrome */ if ( testPalindrome( copy, 0, copyCount - 1 ) ) { printf( "\"%s\" is a palindrome\n", string ); } /* end if */ else { printf( "\"%s\" is not a palindrome\n", string ); } /* end else */ return 0; /* indicate successful termination */ } /* end main */ void removeSpace(char src[], char copy[], int *cnt) { } int testPalindrome( char array[], int left, int right ) { }
