is it possible to create a random number generator for a given range without repeating number and without using pseudo random number generator method??
Yes it's possible:
- Pick a random number from that range
- Remove that number from the range
- Repeat until the range it exhausted
Your question now should be, how do I pick a random number from a range and keskiverto's answer should be useful for this. Specifically shuffle www.cplusplus.com/reference/algorithm/shuffle/
