[* For Intel x86/x86_64 Not for BM Power PC Thanks Josh for Comment]

void main()

{

int i=9;

char *p;

clrscr();

p = (char) &i ;

printf("\n First Byte : %d",*p);

p++;

printf("\n Second Byte : %d",*p);

getch();

}

You will Get Answer 

First Byte : 9

Second Byte : 0

It proves that C is using Little-Endian.
