Code WTF

[kot_ivanovich]

Набрёл случайно на community code_wtf. Особенно интересным оно мне не показалось, но вспомнил о замечательном WTF, который лично автор этих строк когда-то нашёл в boot-code нашей системы, и потом долго и с воплями бегал по конторе, всем показывая. Код, кстати не наш, а IBM...

/*-----------------------------------------------------------------------------+
| hex2ascii() converts a hex to ascii.
+-----------------------------------------------------------------------------*/
char hex2ascii(char in)
{
char rc = 0;

if (in <= 9)
{
rc = in + '0';
}
else if (in >= 0xa && in <= 0xf)
{
rc = in + 'a'-10;
}
else if (in >= 0xA && in <= 0xF)
{
rc = in - 'A'+ 'a'-10;
}
return rc;
}
Ну и, если уж они так настаивают, приведем заголовочек:

/* netLib/net_boot.c, openbios_common, openbios_6xx 5/19/99 08:47:07 */
