Testing Endianness Of A Platform

A small code to find the endianness of the current platform for which the code will be compiled & where the executable from the code will be run:

#include

#define BIG_ENDIAN 0

#define LITTLE_ENDIAN 1

int TestByteOrder(void);

int TestByteOrder(void)

{

short int word = 0x0001;

char *byte = (char *) &word;

return (byte[0] ? LITTLE_ENDIAN : BIG_ENDIAN);

}

int main(void)

{

printf("The Endianness of the platform is: %s\n", TestByteOrder() ? "LITTLE Endian" : "BIG Endian");

return 0;

}
