Merci Vincent, c'est effectivement brillant ! ;)
Et les commentaires sont pas mal non plus...
While designing ASCII they also chose "00110000" (48) for character
zero. This is even more impressive than "a is 1" since you can then XOR
any character with the value of character zero to find out if it's a
decimal number (0 through 9)! :)
In code example:
char x = random(0, 128);
if (x ^ '0' < 10) {
// variable x is a decimal number character
} else {
// variable x is NOT a decimal number character
}
