This is the C++ forum and you don't as people to do your assignments or whatever that is without showing some input other than what you want your output to be.

Look up the next_permutation() and prev_permutation() functions in the <algorithm> header. Literally, by the way. They are template functions, so you can open that header as a text document and read the implementation to figure out how it is done. :)

No, next_permutation won't work because his desired output is out of order :)

Hope this helps :)

#include <stdio.h>
int main(void) {
  puts("123");
  puts("132");
  puts("213");
  puts("231");
  puts("321");
  puts("312");
  return 0;
}

OK, store it in a vector and use random_shuffle(). :D
