Write a program to get the higher and lower nibble of a byte without using shift operator?

Answer 1

#include<stdio.h> struct full_byte { char first : 4; char second : 4; }; union A { char x; struct full_byte by; }; main() { char c = 100; union A a; a.x = c; printf("the two nibbles are: %d and %d\n", a.by.first, a.by.second); }
