Re: To write such an expressive code D

[Dennis Ritchie via Digitalmars-d-learn]

Please help.

import std.stdio;
import std.stdio;
void main()
{
        /* return (a xor b xor c) */
        int nobitxor(int a, int b, int c) {
                return (a + b + c == 2 || a + b + c == 0) ? 0 : 1;
        }
        
        int a, b, c;
        
        a = b = c = 0;
        
        foreach (i; 0 .. 8) {
                if (i > 3)
                        a = 1;
                if (i == 2 || i == 3 || i == 6 || i == 7)
                        b = 1;
                if (i % 2)
                        c = 1;
                writeln(a, b, c, ' ', nobitxor(a, b, c));
                a = b = c = 0;
        }
}

Output:

000 0
001 1
010 1
011 0
100 1
101 0
110 0
111 1

You need to function nobitxor(int a, int b, int c) not used 
bitwise/logical and mathematical operations.
