Put it into a vector, then randon shiffle it, and get the first element. Here is an
example:

int doIt(){
 declare std::vector<int> variable;
 while input.isgood, put input into variable.
 call std::random_shuffle with variable;
 print variable[0], a random number from the list of inputs given.
}

You could certainly do what firstPerson has suggested. Or you could just generate independent random numbers: http://programmingexamples.net/index.php?title=CPP/RandomNumbers
