It outputs 41 because, funny enough, that's it's default output. To set a range: rand() % size; //where size is your range. This will return a number between 0 and size inclusively. I do recommend using srand(time(NULL)); along with is to aid in the randomization. So try something like: #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main () { srand(time(NULL)); cout << rand() % 100 + 1 << endl; return(0); } by adding the one we change the inclusion to 1 and 100, (instead of 0 to 99) like your above request.

#include <iostream> #include <cstdlib> using namespace std; int main() { { cout << rand() << endl; } }
