char*t="  0 _ _0 ___0 _ _   0_. (0=./_0=._*0=.\\_0_. ) 4 \\  (2.oO-1,._ 3.oO-)5 /  4< / (6 ]> 6:   6 [< )5> \\  (7 \"_ 7: _ 7 \"_ ) ";i,r,d;f(char*p){while(r++<35){d=t[i]-48;putchar(t[d<0?i:i+p[d]-48]);i+=d<0?1:5;r%7?0:puts("");}}

With newlines and whitespace for better readability:

char* t = "  0 _ _0 ___0 _ _   0_. (0=./_0=._*0=.\\_0_. ) 4 \\  (2.oO-1,._ 3.oO-)5 /  4< / (6 ]> 6:   6 [< )5> \\  (7 \"_ 7: _ 7 \"_ ) ";
i, r, d;
f(char* p)
{
    while (r++ < 35)
    {
        d = t[i] - 48;
        putchar(t[d < 0 ? i : i + p[d] - 48]);
        i += d < 0 ? 1 : 5;
        r % 7 ? 0 : puts("");
    }
}

The whole thing is fairly brute force. It uses a table that contains one entry for each of the 35 (5 lines with length 7) characters. Each entry in the table is either:

  • A constant character: , (, ). Length of table entry is 1 character.
  • Index of body part, followed by the 4 possible characters depending on the part selection in the input. Length of table entry is 5 characters.

The code then loops over the 35 characters, and looks up the value in the table.
