Is it possible to generate a random 6 digit number, but only using the numbers 1,2,3,4,5,6 and not having it repeat any numbers within. Example: 345621 124356 453216 1,2,3,4,5,6 has to be used once, so its basically scrambling the 6 numbers

Though your programming language may have a library function to do so out of the box. Ex: for C++ look up the random_shuffle() function.

I just though of something.

I guess I want to scramble the number 123456, kind of like word scrambler where you take comfort and make it trofocm

I want to do the same thing with 123456, but have a whole list of it.

Again, if you want all the permutations of a set your programming language may have a library function to do it. Ex: for C++ look up the next_permutation() function.

#include <iostream>
#include <algorithm>

int main() {
char s[]="123456";

do {
std::cout << s << '\n';
} while (std::next_permutation(s,s+6));
}
