Finding out the system is little endian or big endian system

Here first a value 1 is stored in a int variable. Address of that variable is taken and cast as a char address which will work only on the first byte of the word. If a value one is available in the char then its little endian system otherwise its big endian

	# include <stdio.h>
	# include <conio.h>
	void main()
	{
	int i = 1;
	char *c = (char *) &i;
	if (*c)
	printf("Little endian");
	else
	printf("Big endian");
	getchar();
	}
