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;
}

Hi, i have a doubt
in the statement
p=(char *)&a;
why we are used (char *) here

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

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