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;
}

Binary equivalent of 5.375 in normalized form is;
0100 -> 4
0000 -> 0
1010 -> A
1100 -> C
0000 -> 0
0000 -> 0
0000 -> 0
0000 -> 0
Since the PC's (Intel processors) use " LITTLE ENDIAN" byte order, the higher-order0 byte of the number is stored in lowest address. The result is written from bottom to top.
0100 -> 4
0000 -> 0
1010 -> A
1100 -> C
0000 -> 0
0000 -> 0
0000 -> 0
0000 -> 0

There is an option error.
Actually, the correct one is Option A.
8086 microprocessors store data in hexadecimal.
0100-4.
0000-0.
1010-A.
1100-c.
0000-0.
0000-0.
0000-0.
0000-0.

The data type of 'a' is in 'float' but the pointer variable used for that is in 'char'. So is it possible to take float type value in character data type?

Can you please give the explanation in detail?

Its because the machine in which that program executed remains a little endian machine. See this for explanation:
