Hex is the easiest representation of binary. It is very easy to read if you
know
how the hex digits are structured:
0 - 0000
1 - 0001
2 - 0010
3 - 0011
4 - 0100
5 - 0101
6 - 0110
7 - 0111
8 - 1000
9 - 1001
A - 1010
B - 1011
C - 1100
D - 1101
E - 1110
F - 1111
You can also make a little C program to translate every hex digit you read
into the
equivalent binary digits.
#include <stdio.h>
main()
{
unsigned int y;
while ((x = getchar()) != EOF)
{
switch (x)
{
case '0': printf ("0000"); break;
case '1': printf ("0001"); break;
case '2': printf ("0010"); break;
case '3': printf ("0011"); break;
case '4': printf ("0100"); break;
case '5': printf ("0101"); break;
case '6': printf ("0111"); break;
case '7': printf ("1111"); break;
case '8': printf ("1000"); break;
case '9': printf ("1001"); break;
case 'A': printf ("1010"); break;
case 'B': printf ("1011"); break;
case 'C': printf ("1100"); break;
case 'D': printf ("1101"); break;
case 'E': printf ("1110"); break;
case 'F': printf ("1111"); break;
default: printf ("%c", x); break;
}
}
}
