If the binary eauivalent of 5.375 in normalised form is 0100 0000 1010 1100 0000 0000 0000 0000, what will be the output of the program (on intel machine)?
#include<stdio.h>
#include<math.h>
int main()
{
float a=5.375;
char *p;
int i;
p = (char*)&a;
for(i=0; i<=3; i++)
printf("%02x\n", (unsigned char)p[i]);
return 0;
}

@satish & @megha : in exp p=(char *)&a;
p is a pointer of type char and a is a interger but a pointer is always of type unsigned constant interger so what we are doing is typecasting the address so that so that the compatability remains........

If little endian prints from bottom to top, then why D is not correct.

How do we decide whether to use big endian or small endian?

p=(char *)&a;
satish i thik (char*)this is for type casting as
a is float and p is char
