By using a pseudo random number generator and a map container (really convenient for pairs and also it has some mechanism to check duplicate keys (IDs)) like this snippet. #include <map> #include <random> #include <string> //... random_device rd; mt19937 gen( rd() ); int main() { string names[10] = {"boo","doo","koo","moo","joo","foo","loo","zoo","xoo","roo"}; map <int, string> rec; uniform_int_distribution<> ID(1000, 9999); for (auto i = 0; i < 10; ++i) rec.insert( make_pair(ID(gen), names[i]) ); } insert won't replace already added keys (IDs)
