How do you generate a random number without duplicates in C++?

6 Answers. Just generate the numbers 1 to 9, then shuffle them randomly using std::random_shuffle . int nums[9] = {1, 2, 3, 4, 5, 6, 7, 8, 9}; std::random_shuffle(nums, nums + 9); This will leave nums with the numbers from 1 to 9 in random order, with no repetitions.
