Count from 1 to 1000

[Soldier . . .]

Most popular compilers for c/c++ accept the 0b prefix.

Code:

    int i = 0;

    i = 42;                 // decimal
    i = 0x2a;             // hex
    i = 052;               // octa
    i = 0b00101010;   // binair

It's a bit of a habit to write in bytes and not in nibbles or even smaller like 11.
