use rand() % 2 + 1
store the return value in a variable, then put statements like if value == 1 then rock, else if value == 2 then paper else scissors,

That would be rand() % 3 + 1 ... and be warned that the low bits of rand() aren''t that random.

(int)(3 * ((double)rand() / (double)RAND_MAX)) + 1

Slower, due to the * and / though.
